Hi! I’m building an early-stage MVP for a battery-powered wearable bracelet designed to support emotional connection between young children and caregivers during transitions (e.g., daycare drop-off).
I’m looking for an experienced embedded / firmware engineer to help me build two working physical prototypes (not manufacturing-ready) that demonstrate the core interaction.
This role is firmware + embedded hardware only. I am not looking for mobile app development at this stage.
⸻
🔧 What we’re building (MVP scope)
• A small wearable bracelet (prototype form factor)
• Bluetooth Low Energy (BLE)
• One large physical button
• Haptic vibration and/or LED light feedback
• Button press on one bracelet triggers vibration/light on the paired bracelet
• Communication via BLE (phone will act as gateway later)
• Focus on low power / battery operation
• No screen, no GPS, no cellular, no audio, no cloud dashboards
The goal is to prove the interaction works and test with real families.
⸻
📦 What I expect as deliverables
• Firmware running on a suitable BLE dev board (ESP32, nRF52, or similar)
• Two physical, wearable prototype units I can hold and use
• Basic enclosure or wearable mounting suitable for testing (3D-printed or off-the-shelf is fine)
• Clean, documented firmware
• A simple BLE protocol that a future iOS app can integrate with
This is not a manufacturing or mass-production project yet.
⸻
🧠 What I’m looking for in you
• 5+ years experience in embedded systems / firmware
• Prior work with BLE, battery-powered devices
• Experience with wearables, IoT, or medical devices is a plus
• Comfortable prototyping quickly using dev boards
• Thoughtful about power usage and simplicity
• Open to collaborating with a separate mobile app developer later
⸻
🚫 What this project is NOT
• Not robotics
• Not AI / ML
• Not full IoT cloud platforms
• Not web dashboards
• Not mobile app development
• Not GPS tracking
If you prefer large, complex systems, this probably isn’t the right fit.
⸻
⏱ Timeline & budget
• Target: working prototype within ~6–8 weeks
• Budget: open to discussion, looking for a clear proposal and breakdown
• This may evolve into a longer-term engagement if the MVP is successful
⸻
❓ To apply, please answer briefly
1. Have you built BLE, battery-powered wearable devices before?
2. Which platform would you recommend for this prototype (ESP32 vs nRF52, etc.) and why?
3. Would you deliver physical prototypes, not just firmware code?
4. Rough timeline and cost estimate to reach a working proof-of-concept
Thank you — I’m excited to work with someone who values simplicity, thoughtful design, and real-world usability.

We are a lidar perception startup at an early stage. We are looking for a local engineer to support our demo's and deployments. Additional work will be around perception development and improving our product usability.
We already have developed a DBSCAN lidar rules based algo. however its not consistent in its ability to detect objects. we currently have 8 classes we look for. our tracking algo and prediction algo are also in place. I need help refining and making this lidar perception class leading for non GPU applications. This can even be a weekend and evening side gig for a pro working for someone else in the region. The rate is Initially low at $60/hr but we are willing to also provide project based commissions. Once we lockin our seed round we will be looking to bring people on full time.
Being in the Seattle area is mandatory.
Client's questions:
what experience do you have with CPU based 3d lidar detection?
Are you based in Seattle?
if given the opportunity to join as a permanent full time employee would you be able to?

After agreeing to do the work, they struggled to extract the data required to do the job. So I ended up having to extract the point clouds for them. No big deal.
Freelancer then went silent for a week and a half upon checking in with them they told me that they were no longer doing the job. This sets us back tremendously on our timeline and I'm admittedly pretty upset.
Normally I would have a formal recommendation with a lot of praise but I for the first time can't form a recommendation because I don't know the quality of their work. Literally zero hours were billed for this job.

We’re looking for experienced PCB designers (Altium/KiCad) who work with hardware clients and can introduce projects that need PCB fabrication or turnkey PCBA after layout.
What we need:
* Warm introductions to clients who are building hardware (commercial / non-ITAR)
* Ideal situations: tight lead times, parts constraints, second-source/backup supplier needs, cost-down builds
* Optional: ongoing PCB layout/DFM support if you also want design work
What we offer:
* Fast quoting + DFM feedback, reliable manufacturing + supply chain (15+ years serving clients)
* We will not bypass you — we’re happy to keep you involved and can sign a simple non-circumvent agreement
* Referral compensation to be discussed and agreed after a quick call (case-by-case)
To apply, please share:
* The types of clients you work with (IoT/industrial/medical/audio/etc.)
* Your location/time zone and typical project volume (how often clients need builds)
I am refining a shared-control medical robotics platform that steers an echographic probe while the clinician teleoperates it. The immediate task is to craft, tune, and validate the control algorithms that keep the probe stable on a virtual human phantom surface and react safely to operator inputs.
My overriding focus is on control algorithms, with impedance control taking center stage. All development and testing happen inside CoppeliaSim, and the controller must rely on Pinocchio for accurate rigid-body dynamics. Once the algorithm behaves as expected in simulation, we will migrate it to the real robot.
What I need from you:
• A fully working impedance controller coded for easy integration with our existing CoppeliaSim scene
• Direct calls to Pinocchio for real-time dynamics, including mass matrix, Coriolis, and gravity terms
• A short stability and performance report (plots and key metrics) demonstrating safe surface interaction and smooth operator hand-over
• Clean, well-commented source files plus a brief setup guide so my team can reproduce every result on our end
I am open to your choice of C++ or Python as long as it runs at control-loop rates inside the simulator. If you have prior experience coupling CoppeliaSim with Pinocchio or have published impedance or hybrid position-force controllers, let’s talk—your expertise will accelerate this project’s clinical impact.
The robot is Kuka iwa7 R800 with 7 dof

About CloudChef
CloudChef is a robotics startup building robotic cooking systems capable of performing real kitchen tasks end-to-end. We’re developing learning-based manipulation policies (ACT / VLA-style) and need a strong simulation foundation to train and validate these systems before deploying on real hardware.
Role
We’re looking for a Robotics Simulation Engineer to build and maintain a kitchen manipulation simulation environment for 6-DoF robotic arms (including bimanual setups). The simulator will be used to generate trajectories + camera observations, and to evaluate policy performance in simulation.
What you’ll do
• Build a scalable kitchen simulation environment (Isaac Sim preferred; MuJoCo / PyBullet acceptable if justified)
• Integrate our robot models (URDFs provided) and common kitchen objects/tools
• Implement trajectory generation pipelines (scripted, IK-based, motion planning, or hybrid)
• Generate synthetic datasets with multi-camera observations (wrist + overhead cameras; RGB required, depth optional)• Add domain randomization (object layout, lighting, camera pose noise, materials/texture variation, etc.)
• Design and implement task evaluation criteria:Define what “success” means for a given task
• Implement robust metrics and automatic success/failure labeling
• Provide evaluation reports across large batches of episodes
What we care about
This is not a one-off demo — we need a simulator that can reliably produce thousands of episodes, clean data, and repeatable evaluation results for model training and benchmarking.
Deliverables
• Runnable simulation project + documentation
• Episode generator scripts (seeded/reproducible)
• Dataset output per episode:robot states (joints, actions, timestamps)camera streams (wrist + overhead) metadata (randomization parameters, seeds, task config)
• Evaluation harness producing:metrics per episode success/failure labels aggregate summaries across runs
Required experience
• Robotics manipulation simulation IK / motion planning / controller integration
• Camera simulation + dataset generation
• Python engineering + clean tooling
Nice to have
• Isaac Sim / Omniverse experience
• Synthetic data pipelines + domain randomization
• Familiarity with imitation learning datasets (ACT-style, LeRobot-style, etc.)
When applying, include
• Which sim stack you propose and why
• Past manipulation sim work (video, repo, screenshots)How you’d approach large-scale trajectory generation
• How you’d design evaluation metrics that generalize across tasks
Optional (tiny add-on line that improves candidate quality)
Bonus: Experience building evaluation metrics that correlate with real-world success (sim-to-real).
I am setting up a UAV operation and warehouse in Turkey focused on inspection, mapping, and advanced aerial data collection. I am looking for a UAV software specialist to support flight control integration, mission planning, and payload integration for both multirotor and fixed-wing VTOL platforms.
The work includes configuring and customizing autopilot systems (PX4/ArduPilot), integrating EO/IR cameras, gimbals, and sensors, and ensuring reliable mission execution, telemetry, and data capture. Future phases may include AI-based analysis and advanced inspection or disaster-response features.
We are developing a manipulation pipeline using an Elephant Robotics myCobot 320 Pi (2022) running on ROS 2 Humble. The robot is equipped with a custom end-effector setup including a "Pro Force" adaptive gripper and a custom 3D-printed vertical mount for an Intel RealSense camera.
We have successfully generated a MoveIt configuration and edited the URDF to include our custom geometry. However, we are facing persistent "initialization collisions" and stability issues where the planner detects self-collisions immediately upon spawning, likely due to "ghost" states (robot collapsing to 0,0,0) or improper ACM (Allowed Collision Matrix) configuration.
Hardware & Software Stack
Robot: myCobot 320 Pi (2022 version)
OS/ROS: Ubuntu 22.04 / ROS 2 Humble
Planner: MoveIt 2 (OMPL, RRTConnect)
End-Effector: Pro Force Gripper + Custom Vertical Camera Mount (Box geometry: 10cm x 4cm x 12cm)
Current Status
URDF: We have manually updated the URDF to include ros2_control tags (using mock_components/GenericSystem), fixed joint offsets, and added collision geometry for the camera mount.
SRDF: We have manually edited the SRDF to disable collisions between the gripper internals and the camera mount.
Visualization: The robot appears correctly in RViz (grey model, correct custom geometry orientation).
The Specific Problem (The "Ghost" Collision) Despite the robot appearing visually correct in RViz, the MoveGroup node frequently aborts planning requests immediately upon launch or execution. The logs indicate a collision between the Gripper Assembly and the Robot Base, suggesting the robot momentarily initializes with all joint angles at 0.0 (collapsed state) before the controller takes over.
Overarching goal is to get simple detection of object, and have the robot move and pick it up.
We are looking for an experienced network engineer with strong expertise in secure tunneling, proxy systems, and censorship-resilient configurations.
The scope of work includes:
• Setting up a secure proxy/tunneling solution (e.g., V2Ray/Xray or equivalent) that can reliably bypass restrictive network filtering.
• Providing a subscription link or configuration that can be imported into standard clients (e.g., v2rayN on Windows).
• Ensuring the setup uses modern obfuscation protocols (e.g., VLESS + REALITY or VLESS + WebSocket + TLS) to maximize reliability in high-censorship environments.
• Explaining how to use the setup on Windows.
• Optional: guidance on how to share configurations with up to 5 users safely.
Required experience:
• Strong background in network proxy and tunneling technologies.
• Direct experience building censorship-resistant solutions for Middle Eastern networks or similar restrictive environments.
• Familiarity with secure transport protocols (TLS, WebSocket, QUIC).
• Comfort with Linux server deployment and configuration.
Deliverables:
• A working configuration or subscription service.
• Step-by-step usage instructions.
• Short support session to verify connectivity.
Please describe relevant prior experience with secure proxy or anti-censorship networking in your application.
Description:
I’m new to ROS 2, Gazebo, and ros2_control, and I’m looking for an experienced ROS tutor/developer to help me debug a simulation issue.
I’m working with ROS 2 Jazzy and Gazebo Harmonic (gz-sim8) on a simple differential-drive robot with a 2D LiDAR. The robot spawns correctly in Gazebo and the LiDAR topic appears, but ros2_control fails during hardware initialization and the controller_manager service never becomes available. Because of this, controllers don’t start and the robot can’t be driven.
At this stage, I’m not sure whether the issue is due to:
URDF / Xacro configuration
ros2_control YAML controller setup
gz_ros2_control plugin configuration
or something incorrect in my initial ROS / Gazebo environment setup
I’ve already tried debugging with AI assistance, but the setup has become more complicated over time. I’m specifically looking for hands-on guidance from someone experienced who can explain what’s going wrong and help fix it in a clean, beginner-friendly way.
What I need help with:
Getting joint_state_broadcaster and diff_drive_controller running
Verifying ros2_control + Gazebo integration
Confirming /cmd_vel and /scan work correctly
Identifying and correcting any fundamental setup mistakes
Deadline: Tonight (urgent)
I can share logs, configs, and files, and I’m happy to work live if needed.
This would suit someone with strong experience in ROS 2 Jazzy, Gazebo (gz_sim), and ros2_control, and who’s comfortable helping beginners.
Pls ask for my discord if interested, thank you.
