I run an education-focused YouTube channel watched by curious minds of every age, so each video must speak to children, teenagers, and adults alike without ever sounding dull or overly academic. For that reason, I need well-researched scripts that read like a friendly conversation, sprinkle in a dash of humor, and still stand on solid, verifiable facts.
What you’ll be writing
– Topics span Science & Technology breakthroughs, History & Culture stories, Health & Wellness insights, plus the occasional deep dive into AI, machine learning, robotics, geopolitics, sci-fi thought experiments, spirituality and even politics. Variety keeps the channel fresh, so an eagerness to explore any field is essential.
How the scripts should feel
– Conversational, engaging and periodically humorous entertaining, yet always educational. Think accessible language that a 10-year-old grasps while an adult still learns something new.
Core deliverable
• One complete video script (about 1,200–1,500 words for an 8–10-minute runtime) formatted for easy voice-over narration, including:
– A hook that pulls viewers in within the first 15 seconds
– Structured sections that flow like a story, each backed by credible sources
– A concise outro with a question or CTA to encourage comments and shares
– A reference list of articles, journals or data sets used
Acceptance criteria
• Zero plagiarism and properly cited facts
• Clarity and storytelling flow validated by a readability tool (Grade 6–8 target)
• Delivered as a Google Doc or Word file, ready for on-screen presenter notes
If you can blend solid research with approachable storytelling, let’s make learning irresistible together.

I have a Cube+ running Ardupilot on a small marine platform and all of the hardware—autopilot, power rails, laptop with Mission Planner, and the custom PWM-driven servos—is already wired and bench-tested. The remaining work is strictly on the software side: Mission Planner and Ardupilot parameters must be tuned so the Cube+ drives each servo correctly, and a few bespoke servo behaviours need to be scripted.
What’s needed
• Configure all relevant Mission Planner and Ardupilot settings so the servos arm safely, respond to commands, and survive power-cycle tests.
• Program the custom servo functions (Lua scripting or equivalent) that translate navigation commands into the exact control movements we require.
• Validate everything first on the bench, then on-water here in Seattle.
This wraps when each servo tracks its programmed logic, Mission Planner shows a clean status screen, and I have the final .param file plus the script with a short usage note.
All work must be done locally—hardware stays in my Seattle workshop and the final water trials are on Lake Union—so the ability to drop by in person is essential. If you’re comfortable with Ardupilot, Cube+, and Mission Planner and enjoy hands-on testing, let’s sync up and finish this integration.

Do you excel at science and technology communication? Do you strive to communicate complex topics simply like SmarterEveryDay, Physics Girl, Carl Sagan, Bill Nye, or Andrew Ng? If you're a science and tech nerd with a gift for analogies, metaphors, and synthesis that turns the obscure into easy-to-understand ideas, then this is the project for you.
We're an AI startup that has built a world model and platform for applied physics. Applications range from construction to satellites to robotic navigation. Our architecture is the first of its kind. We don't use vision or language models, for instance. We've found that investors and customers are slow to grasp our technology. As technologists and physicists, we're not experts in communicating our technology in ways the average person can understand. That's where we need your help.
We are looking for someone who is immediately available to digest the technical and scientific concepts of our technology (we'll provide the materials and can have calls to explain everything). Using your technical and scientific communication skills, we want you to come up with easy to understand terms, phrases, and metaphors. For example, instead of talking about how we can predict the viscosity and flow rates of Bingham materials with our physics, we could use the example of a robot making a cake and knowing if the batter is too thin or thick. Or, how our system cannot hallucinate like LLMs because we are causal and deterministic, which might translate to something like language models make the best guess but our system does the math to get a definite answer.
This will help us with our investor pitch deck and website materials. For us a clever analogy is 10x better than a well-written description. This isn't about number of words. It's about compelling ideas accessible to the average investor.
Deliverables: 5-10 compelling ways to communicate our core concepts and advantages.
For top consideration, please send 1-2 examples of a highly complex idea that you made simple - ideally in just a couple of sentences.
Those with technology or science backgrounds are highly desired.
Looking for an experienced Youtube script writer. You will be creating 15 minute long scripts about AI/Robotics.
Here is an example of the type of content - https://www.youtube.com/watch?v=tjFHRVr7aNE
You will be required to do the writing + clip selection/sourcing for the videos that appear.
The pay is $60 per script to start. I will need 2 scripts a week. If you meet deadlines and perform well, the pay can increase upwards of $100+ per script.
Please send scripts that are similar for me to review.

Unmatched Mobile Firepower: Tanks are equipped with large-caliber cannons (e.g., 120mm) that can fire a variety of powerful ammunition, including armour-piercing and high-explosive shells, enabling them to destroy enemy tanks, fortifications, and other hard targets from long distances.
Superior Protection: The heavy, specialized armor (like composite or reactive armor) of a main battle tank provides significant protection for the crew against most small arms fire, shrapnel, and many anti-tank weapons, making them highly survivable on the battlefield.
Battlefield Mobility: Utilizing tracks rather than wheels gives tanks excellent cross-country mobility, allowing them to traverse rugged terrain, cross trenches, and overcome obstacles better than most other vehicles, ensuring forces can be quickly positioned where needed.
Shock Effect and Intimidation: The physical presence of a massive, heavily armed tank has a significant psychological impact on enemy troops, boosting the morale of friendly forces while intimidating the opposition.
Versatility in Combined Arms Operations: While vulnerable when alone, tanks are a crucial part of a combined arms approach, working in concert with infantry, artillery, and air support. They can spearhead assaults, provide direct fire support to advancing infantry, or act as mobile defensive strongpoints.
Breaching Defenses: Historically, tanks were

I’m preparing two motivated 7th- and 8th-grade students for an upcoming Robotics Olympiad. They already understand the basics of coding and can assemble and drive a simple robotic car, but they now need a mentor who can take them to the next level.
The core of the engagement is hands-on, challenge-driven coaching delivered online (preferred) or in person if you are nearby. Sessions should steadily deepen their knowledge while producing small, demonstrable projects they can refine into a competition-ready solution.
Focus areas
• Advanced programming techniques (efficient C/C++ for embedded systems)
• Sensor integration—ultrasonic, IR, line-tracking, IMU, or similar modules
• Working confidently with Arduino Uno and Nano boards using the Arduino IDE
If you can weave in elements of mechanical design or strategy for competition scoring, even better, but the items above are mandatory.
What I’d like to see from you
• A brief outline of a 3 week training roadmap with milestones
• Examples (video or repo links) of student projects you have supervised that involve multiple sensors and clean, well-commented code
• Your availability for 1- to 1.5-hour sessions
• Any suggestions for low-cost components or kits that keep parts sourcing simple
Other Technical Requirements:
The training will focus specifically on the Arduino Nano microcontroller. The trainer must be proficient in working with the following components and sensors:
Microcontroller: Arduino Nano.
Sensors: Dual IR Sensors (Line Following), Ultrasonic Sensor HC-SR04 (Obstacle Avoidance), and LDR (Light Intensity Detection).
Actuators: DC Motors with L298N/L293D Motor Drivers.
Concepts: PWM Speed Control, Sensor Fusion, and Nested Conditional Logic.
Key Learning Objectives:
The students need to master complex tasks where multiple sensors work simultaneously. The trainer must be able to teach:
Advanced Line Following: Smooth navigation and T-junction detection.
Obstacle Detour Logic: Detecting an obstacle, navigating around it, and successfully recovering the line.
Environmental Adaptation: Using LDR sensors to trigger actions (like turning on headlights or adjusting speed in tunnels).
Integrated Missions: Combining Line Following + Obstacle Avoidance + Auto-Lighting + Parking into one seamless code.
Troubleshooting & Calibration: How to adjust sensor thresholds and motor speeds based on competition floor conditions.
The students learn quickly and enjoy experimenting, so I value a coach who is patient, encouraging, and willing to push them with real debugging tasks rather than pre-baked solutions. If this sounds like a good fit, let’s discuss your approach and timeline.

At the time of hiring, the job was described as 8 hours per day with flexible timing. Later, the contract was changed to “on-demand,” but the expectation of 8 hours per day was repeated, which caused some ambiguity.
Tasks were short (2–5 minutes each) and unpredictable, with rare periods of larger batches. This made scheduling difficult, as availability was expected even when tasks were limited. While I did my best to remain present and follow the instructions given, there were differences in expectations regarding logged hours, which ultimately led to disputes.

My experience with this client was deeply concerning. After successfully completing the agreed-upon work and delivering it on time, the client attempted to manipulate the situation by demanding a refund. When I respectfully declined—since the work was completed as requested—he resorted to threats and intimidation tactics in an effort to force a refund.
This behavior is highly unprofessional and unethical. It's clear that the client was trying to exploit the Upwork refund system. I strongly recommend documenting everything if you choose to work with this client, and be prepared for potential disputes even after successful delivery. Freelancers deserve to be paid fairly for their time and expertise—this client does not seem to respect that.

Embedded Engineer — XM125 (A121) Radar + IMU Sensor Fusion for Precision Linear Travel Tracking
Project Overview
I am building a handheld device that requires high-precision linear travel distance tracking over uneven surfaces using:
• XM125 (A121) radar or similar
• IMU (accelerometer + gyroscope, possibly magnetometer)
• Real-time embedded sensor fusion
The radar provides surface-relative displacement via Doppler/phase-based measurement. However, surface curvature and handling introduce tilt and rotation, which can cause angular motion to be falsely interpreted as linear travel. The IMU must continuously estimate orientation and angular velocity so that:
• Linear translation is preserved
• Rotational motion is rejected or compensated
• Radar measurements are gated or nulled during excessive tilt
The goal is robust, drift-minimized linear displacement output under real-world motion, vibration, and micro-slip conditions.
⸻
Scope of Work
You will design and implement:
1. Radar displacement extraction from XM125 (A121) or equivalent
2. IMU orientation and angular motion estimation
3. Sensor fusion pipeline (Kalman/EKF/complementary or similar)
4. Tilt-aware gating and correction of radar measurements
5. Fully integrated embedded firmware running on target hardware
6. Calibration and validation on uneven surfaces
⸻
Hardware Environment
• Radar: XM125 (A121) or similar
• IMU: To be selected jointly
• MCU: STM32 / ESP32 / similar
• Interfaces: SPI / I2C / UART
You will collaborate directly with the project’s electrical engineer for hardware integration, timing, sensor selection, and validation.
⸻
Deliverables
• Fully working embedded firmware running on target hardware
• Integrated radar + IMU sensor fusion system
• Calibration and filtering routines
• Test results demonstrating reliable linear displacement tracking
• Clear technical documentation
Preferred Experience
• XM125 / A121 or similar radar modules
• Motion tracking / odometry systems
• Robotics perception or inertial navigation
• Wearable or handheld embedded systems
⸻
Proposal Requirements
Please include:
1. Relevant radar or IMU fusion projects
2. Your approach to separating linear translation from angular motion
3. Estimated timeline
4. Example code or GitHub (if available)

Goal: Tune and validate autonomous flight control behavior for small autonomous blimps in simulation.
Project Overview
We are developing autonomous blimps (2 m³, 4 m³, 20 m³) using a Cube Orange ArduPilot-based controller. Blimps have slow dynamics and high wind sensitivity, and off-the-shelf multirotor tuning does not work well. We already have a Gazebo-based blimp simulator set up using open-source code. We need a controls-focused engineer to build an effective controls strategy, tune and validate flight behavior in simulation. The all blimps have the same architecture, with a tri-fin tail and dual independently thrust vectoring fans in an underslung gondola.
Primary Tasks
• Configure and tune Gazebo + ArduPilot (SITL) for 3 blimp sizes (2 m³, 4 m³, 20 m³)
• Adjust vehicle parameters (mass, buoyancy, drag, thrust, control authority)
• Tune control loops for:
• stable vertical takeoff and landing
• steady forward flight and circling
• bounded drift in wind
• Test performance in simulated wind:
• ~20 mph steady wind
• gusts up to ~35 mph
• Identify viable flight mode(s) and control loops (Plane / Copter / VTOL) for stable operation
Deliverables
• Working Gazebo models for all 3 blimp sizes
• ArduPilot parameter sets for each size
• Short writeup summarizing:
• recommended flight mode(s)
• control limits and wind envelope
• known limitations
Required Experience
• Gazebo + ArduPilot or PX4 SITL experience
• Practical PID tuning for slow, high-drag vehicles
• Comfortable modifying sim parameters and autopilot configs
• Ability to reason about wind disturbance and control authority
• Tilt-rotor or thrust-vectoring control experience
Nice to Have
• Experience with airships, balloons, or unconventional UAVs
Time / Budget
• Delivery within one week
• Immediate start preferred
Existing Functionality
• Paperspace instance of gazebo with open source blimp simulator already running, credentials will be provided.

I am a co-founder at Common Labs. I need a Senior Outbound Partner to work directly with me to build our initial sales pipeline.
We sell a "Glass Box" Operating System for industrial robotics. We help MedTech and Aerospace manufacturers automate complex assembly tasks using off-the-shelf hardware.
Deal Size would be $45K to $100K. We'd be selling to Operations Directors in the regulated manufacturing sector.
This is not a script-reading role. I need a "Hunter" who can navigate consultative conversations.
- Identify high-probability targets through manual research and tools like Apollo.
- Execute multi-channel outreach (Email, LinkedIn, Cold Calls) to open new doors.
- Book the meeting for me & co-founders to take the call and close the deal.
What We Need From You:
Seniority: 5+ years of B2B outbound experience (SaaS/Industrial preferred).
No "Spray and Pray": We are in the Seed stage. We need sniper-focused outreach to the top 50 accounts, not mass automation.
US Market Focus: Impeccable English and experience selling to US-based executives is required.
To Apply: Please answer the screening questions below. NO AGENCIES.
Client's questions:
Have you ever sold to industrial, manufacturing, or deeply technical buyers before?
Are you comfortable setting up and working inside our internal Apollo/CRM instance (vs. using your own external tools)? We require full data ownership.
Which sales tools do you prefer for building a high-quality prospect list?

Keeps invoking the presence of a 3rd entity in the contract who's name I've never known. The explanation changes from it being a client of his or his boss, then a partner. Ultimately, he uses this in a way to avoid taking any accountability. He seems more interested in making drama than making a book, as to date, the last draft has an added 100 pages since the previous draft, we're under budget, and ahead of deadline -yet the client closed the contract without logic. He has access to all his master files that I give to all clients at the beginning of a contract in our shared & synced Dropbox archive.

I’m hosting a school seminar for students in Classes 4 to 8 and I need a lively, age-appropriate PowerPoint that explains how to get into our new Robotics stream. The presentation should focus on Admission for Robotics and leave the audience with a clear understanding of what the programme offers and how to sign up.
Here’s what I need the deck to cover, in language that ten- to fourteen-year-olds can easily grasp:
• Curriculum outline – the main modules, hands-on projects, and any cool tech they’ll touch (sensors, LEGO SPIKE, Scratch, Python basics).
• Admission requirements – eligibility, key dates, and a simple step-by-step application guide.
• Class schedule – weekly breakdown, term lengths, and how robotics integrates with their existing computer period.
Design cues: bright colours, big icons, minimal text per slide, plenty of images or diagrams that show robots in action. Animations are welcome if they reinforce a point but please avoid anything that distracts.
Practicalities
– Roughly 12 slides, delivered as an editable .pptx.
– All visuals must be free-to-use or original.
– Include brief speaker notes so any teacher can present confidently.
I’ll supply the school logo; everything else comes from you. Looking forward to seeing a draft that keeps our young tech enthusiasts engaged from the first slide to the last.

Deliverables:
Arduino Mega DB-19 Control Shield (6 units)
Passive shield routing Mega pins to 2× DB-19 connectors (one per leg pair)
Each DB-19: 6× PWM, 3× EN, 3× IS, 3× POT, VCC, GND, 2× spare
2× 3-pin serial headers for inter-MCU communication (TX/RX/GND, crossed cables)
Standard Mega shield footprint; keep unused pins accessible
Combined 3-Actuator H-Bridge PCB (12 units)
Integrate 3× BTS7960-class drivers per board
Connectors: 1× DB-19 (control), 3× 5-pin actuator, 1× 2-pin battery (Molex)

I built a bluetooth carbon dioxide sensor with JLCPCB (4-layer PCB), and the following main components:
— Sensirion STCC4 carbon dioxide sensor with Sensirion SHT40-CD1B for temp/humidity regulation of CO2 readings
— Ai-thinker PB-03F bluetooth module, which has an included PhyPlus PHY6252 chip. This is the chip which has 64 KB SRAM, 256KB flash, 96 KB ROM and will be used for all of the programming, data storage, transmission, etc.
— Powered by one CR2450 battery with 100uF main capacitor, smaller 100nF point of source capacitors, and various resistors/etc.
The job requires programming the PHY6252 to perform the following results:
— Background Mode: Put the Sensirion sensors into sleep mode, waking them for periodic measurements every ~5 minutes. Store the carbon dioxide values until synced with the mobile app (iOS/Android)
— Active Mode: When a bluetooth connection is active, put the Sensirion sensors into continuous measurement mode.
— Syncing/Searching: By default, the BLE broadcasts every 2 seconds until it's connected with the mobile app.

Saimon was not serious as a student, and he wanted us to complete his master's thesis. At first, he told a lot of things that portray him as a victim, and his professor is not giving him enough time to complete his course. We told him we can help him under one condition that he works along with us to complete the work. Later, it was clear he did not want to spend any time to even understand how we are doing the things. We knew it will be a big problem later on, as he will ask us to explain everything from scratch to defend his thesis. We are a consultancy firm we can help him but cannot afford to unethically make someone defend his thesis if he has not put any hours of work in real. It will be immoral to help people like him who will get a degree without putting any work from his end.
