I own a wheeled or tracked robot and need its software finished. I’ll share the exact model, wiring diagrams, manuals, photos, and live-test videos so you can see the hardware and current behaviour.

What I need you to do
• Write clean, well-commented code that gives the robot the behaviours I specify (navigation, obstacle avoidance, remote-app control, or other routines we define together).
• Flash the program to the controller, run on-bench and live tests, and supply a short demo video before I release the final milestone.
• Hand over the full source code plus a plain-language README that explains installation, calibration, and how I can adjust parameters later.
• Provide light post-delivery support for small tweaks or questions.

What I will provide
• Complete documentation: datasheets, wiring diagrams, and any manufacturer manuals.
• Ongoing test feedback and, if you identify missing hardware, prompt ordering of the exact parts you specify.

Proposal details to include
• Examples of past robotics or embedded-hardware projects.
• Any extra components you’d need me to buy, with estimated costs.
• Your total price and delivery time.
• Confirmation that you include after-delivery support.

Milestones can follow a simple structure—planning & parts list, first behavioural demo, and final hand-over—so both of us stay on schedule and everything is clearly validated before payment release. I’m ready to start as soon as I review a clear plan and timeline.

Dr. Ranga from Hyderabad India

Purpose
Recreate our vendor's ROS 1 software for quadrupeds and robot arms as an independent, clean-room implementation that we own, runs on ROS1, ROS 2 or other ROS versions, and removes any and all vendor lock-in.

Why
ROS 1 (Noetic) is end-of-life and the vendor software wont be supported anymore. One maintainable codebase lets us adopt current ROS 2 distributions and future platforms without re-engineering.

Scope

Audit the vendor systems for hardware and software locks (licensing, encryption, signing, authentication, device binding) and report which parts of the stack they affect.
Document the vendor systems' observable behavior as a written specification, per platform.
Build a ROS-independent core library (separate arm and legged modules) from that specification only.
Provide ROS 1 and ROS 2 adapters, including ros2_control hardware interfaces.
Validate against recorded data and live hardware tests.

Required qualifications

Production ROS 1 and ROS 2 experience, including real migrations and software replications from scratch
Strong C++ and Python; framework-independent library design
ros2_control and MoveIt experience for arms
Legged-robot control and state estimation experience (or a specialist partner)
Experience assessing embedded and software protection mechanisms (secure boot, firmware signing, licensing) and what is legally and technically possible to work around
Recording/replay regression testing, CI, clear technical writing
Public open-source ROS track record

Engagement
Milestone-based. Milestone 1 is the specification, recorded test data, and a lock assessment report with a go/no-go recommendation per platform, so we confirm feasibility and cost before committing to the full build.

Deliverables
Lock assessment report, specification, core library, ROS 1/ROS 2 adapters, regression tests and hardware report, documentation and handover, full IP assignment with a defined open-source license and clean-room attestation.

# Reinforcement Learning-Based Robotic Manipulation: Pick-and-Place

I am developing a reinforcement learning-based robotic manipulation system that enables a 5-DOF robotic arm to perform object pick-and-place tasks in a simulated environment.

**Project Overview**

I developed a custom robotic simulation environment using PyBullet and Gymnasium. The environment contains a robotic arm, an object that spawns at different positions within a source box, and a target box where the object must be placed.

**Technical Implementation**

- **Reinforcement Learning:** Implemented a Twin Delayed Deep Deterministic Policy Gradient (TD3) agent combined with Hindsight Experience Replay (HER) to learn goal-conditioned manipulation behavior.
- **Custom Environment:** Designed a Gymnasium-compatible environment with observations, continuous actions, goal information, episode termination conditions, and reward calculation.
- **Robot Simulation:** Built and configured the robotic arm model using URDF/Xacro and integrated it into the PyBullet simulation.
- **Action and Observation Design:** Developed the interface between the RL agent and the simulated robot, including end-effector and object positions, goal information, joint states, and gripper-related actions.
- **Reward Engineering:** Worked on reward design to guide the agent toward object reaching, grasping, and successful placement.
- **Training and Evaluation:** Developed the training and evaluation workflow using PyTorch, with TensorBoard for monitoring training metrics and analyzing agent performance.
- **Debugging and Optimization:** Investigated training stability, reward behavior, gripper operation, object release, and the difference between training and evaluation performance.

**Technologies Used**

Python, PyTorch, Gymnasium, PyBullet, ROS 2, URDF/Xacro, RViz, MoveIt 2, and TensorBoard.

**Current Progress**

The project has established a custom simulation environment and a TD3 + HER training pipeline. I am continuing to improve the agent's reliability, manipulation behavior, and evaluation success rate.

**Project Goal**

The long-term goal is to develop a reliable reinforcement learning agent that can learn robotic manipulation skills and successfully complete pick-and-place tasks under varying object positions.

I'm looking to make a local AI agent that runs on a jetson nx 16 gb.
The agent needs to control the robot and have a personality.
So it needs to move the servos to follow sounds or images, it needs to reason, speak and to understand by itself when to talk.
It is very important we can build a personality of the. robot.
I'm attaching a video to give you an idea.
https://www.youtube.com/shorts/7POre0L0K3c

What is very important is that the robot can function in milliseconds, the jetson is a very powerful machine and should be more than enough to have almost real time responses.

Hey! I'm currently developing a game and I'm looking for someone to create a 3D character model based on the reference images I've provided.
I'd like the character to be built using a modular armor system. Essentially, I want a complete base character (undersuit), with each armor piece modeled as a separate object rather than being permanently merged into the main mesh.
This would include the helmet, chest armor, shoulder pads, gauntlets, waist armor, leg armor, and skates. Each piece should be independently editable and removable, but everything should fit together seamlessly when assembled.
I also have an existing character model that's already fully rigged and animated. I'd like to reuse its skeleton, rig, and animations with this new model rather than creating everything from scratch.
Because of this, I'd like the new character to maintain relatively the same scale, proportions, and joint positions as the existing model to make transferring the rig and animations as straightforward as possible.
I can provide both the existing rigged model and the reference images for the new design.

I have a new robot concept in mind and need an expert who can take it from sketches to a fully simulated model. You will be responsible for the full digital workflow—mechanical CAD, kinematic modelling, control‐system setup, and a repeatable simulation that proves the robot’s motions, loads, and cycle times.

The exact robot category and primary task are still open, so I welcome your input on whether an industrial, service, or educational configuration makes the most sense once we discuss requirements. Likewise, I am flexible on tooling; if you prefer ROS, MATLAB/Simulink, or V-REP/CoppeliaSim (or a mix), explain why it fits the job and I’ll go with the strongest technical argument.

After delivery I should be able to open the model, press “run,” and see the robot perform exactly as documented. If that sounds like a challenge you can meet, please outline your approach, preferred tools, and an estimated timeline when you place your bid.

Hello Paul,

I'm setting up an online shop and I'm looking for a firmware/BLE developer for a custom project. In short: I need software that changes performance parameters (for example the top speed limit, 25 to 45 km/h) on specific e-scooter models over Bluetooth Low Energy. It is intended for use on private property only, and I would sell activation licenses to end customers, so I need full rights to the result.

What I already have: a license server, a shop and a Web Bluetooth activation page.

What I need from you:
- Per-model data/commands that my page writes over BLE (as base64 blocks, per model and firmware version)
- Safety checks: verify model and firmware version before writing, back up original values, restore to stock, safe abort on connection loss, sensible current/temperature limits
- Documentation and a test report

Conditions:
- All code and rights are transferred to me
- The work is original or properly licensed
- No bypassing of cryptographic protection or locked bootloaders. Models that would require this are out of scope
- Milestone payments, final payment after testing on my own scooter

Could you let me know:
1) Have you worked on e-scooter firmware (Xiaomi/Ninebot) before?
2) Which models could you support without bypassing protections?
3) Rough timeline and price?
4) Are you comfortable with this kind of project, including resale of licenses?

Thanks,
Luca
