Find Robot Operating System Projects

I’m looking for a mechatronics or hardware engineer who can help build a working prototype of an automatic haircut machine.

What I need:
• Concept and mechanism design
• 3D CAD model
• Motor and electronics system
• Working prototype

Prefer someone with experience in robotics, motors, sensors, or consumer devices.

Timeline and cost can be discussed.

Goal of the project:
Set up a usable manipulation stack in a ROS2 + simulator-based environment.
Understand the performance bottlenecks of these manipulation stacks using existing ROS2 profiling tools.
(manually) for each stack, define what end-to-end objectives matter and try to specify relative importance of each path.

Steps
Identify a manipulation stack. Criteria:
must run on ROS2
must run on Gazebo-Sim / Isaac Sim (Gazebo is preferable since Isaac is a little more painful to setup)
Candidates:
https://moveit.ai/install-moveit2/binary/
https://developer.nvidia.com/isaac/manipulator

Use ros2_tracing: Tracing tools for ROS 2 to profile the system
What is ROS2 tracing? TL;DR: super light weight tracing tool based on LTTng v2.13 that can be used even in realtime applications with very low overhead. This dumps traces to files, which can then be analyzed by a bunch of tools.
Downstream stuff you can use to process traces:
ros-tracing/tracetools_analysis: default tool that ships with ROS2
skoudmar/Ros2TraceAnalyzer: This claims to be 30x faster than the default tool. Also, they seem to have a way to visualize all this information in a graph.
ROS 2 message flow analysis experiments
broadly looks like there are many tools (e.g. see this discussion thread: ROS 2 Visualization Tools for Architecture)
Write a report on findings and summarize. Furthermore document every single command and approach on how you got there starting from installing ROS2 all the day to project completion.

Skills: Technical Writing, Software Development, Documentation, Data Analysis, Simulation, Robot Operating System (ROS), Software Engineering, Gazebo

Hello,

I am looking for an experienced drone engineer to perform a complete ArduPilot programming/tune of my 17-inch quadcopter.

The quadcopter has the following hardware assembled:
TBS Source X frame, MatekH743 Slim, MatekM10Q GPS, motors 4215-320kv, TBS Lucid 12S 90A ESC, DJI O4 Pro, ELRS 2.4GHz, no battery.

The goal is to perform full autonomous missions reliably using QGC, with the longest possible one-way flight (30km ideally) and as much payload-carrying capability as possible.

We are building a web interface for an autonomous robot using ROS2 Humble on Ubuntu 22.04. We need a long-term partner to expand our existing system (Nav2 mapping, logging, control).

The Stack:
Backend: Python 3, FastAPI, Uvicorn, ROS2 (rclpy), rosbridge_server.

Frontend: JavaScript (ES6+), HTML5/CSS3, roslibjs (critical).

Robot: ROS2 Humble, Nav2, Ubuntu 22.04.

The Role: You will fix bugs, add authentication, and visualize Nav2 maps/telemetry in real-time. You must understand how to bridge the gap between a robot's unstable network and a clean web UI.

To Apply: Please answer: Have you used roslibjs or ros2djs before? Link to a specific project where you visualized ROS topics in a browser.

• Describe how you would display a live map from a /map topic (nav_msgs/OccupancyGrid) on a web browser. Which library would you use?
• What is your strategy for handling WebSocket disconnections between the robot and the browser to prevent the UI from freezing?
• Please paste a link to a GitHub repo or portfolio item where you have used roslibjs or rosbridge specifically.

Project Overview & Priority Requirement
We are recruiting a remote professional development team to build a cutting-edge experimental robot. We welcome applications from talented engineers and developers based in India and Vietnam. We prioritize candidates who can provide high-performance, reliable deliverables suitable for complex experimental environments.

🇰🇷 Priority Communication Skill: Korean Language
To ensure smooth remote collaboration and integration with our team, we are looking for professionals with intermediate conversational and written proficiency in Korean. Please state your Korean level clearly in your proposal.

Core Roles and Requirements (By Area)
We are seeking professionals in three distinct areas. Please specify your area of interest in your proposal.

First, the Robot Arm Mechanical Designer will be responsible for the structural design and dynamic analysis of the experimental robot arm. Proficiency in CAD software (SolidWorks, Fusion 360, etc.) and prior robot arm design experience are essential for this role. Second, the Robot Control Programmer will implement programming for the real-time control and movement of the robot arm. This requires strong proficiency in Python and C++, along with practical implementation experience using ROS (Robot Operating System). Third, the BI Program Developer will be responsible for analyzing and building visualization systems for the large-scale sensor and performance data collected from the robot experiments. Database management skills, experience utilizing BI tools, and proficiency in Python for data analysis are required. A deep understanding of robotics or a related field and strong problem-solving skills are necessary for all positions.

I need a very small custom PCB with:
• 1 high-efficiency SMD LED (such as Samsung LM301B / LH351D with primary optic)
• 1 SMD resistor
• 1 SMD tactile push button
• Powered by a coin-cell battery (such as CR1220)

Target performance:
• Light output: around 20 lumens
• Operating time: about 2–3 hours total, with typical use as short bursts of ~1 minute each (similar to a small flashlight/torch)

Mechanical/layout constraints:
• Coin-cell battery mounted horizontally
• PCB mounted perpendicular to the battery
• On one side of the PCB: LED + resistor
• On the opposite side: tactile push button, to be pressed from the top
• Very compact, minimal component count, single-sided layout preferred

Deliverables:
• Gerber files ready for manufacturing
• BOM (Bill of Materials) using components available for JLCPCB assembly
• CPL / Pick-and-Place file compatible with JLCPCB
• Simple connection diagram or short note explaining LED, resistor, button and battery wiring

Thank you

Hi

I’m building a test setup for gearbox reference data using FLIR sensors.

Gear 1: measure motor tangential, radial, and axial forces (in Nm) plus RPM.
Gear 2: measure tangential and radial forces (in Nm) plus RPM.

The goal is to generate reference force-vs-RPM graphs for each gear. These graphs will later be used for peak-to-peak testing after the gearbox is rebuilt.

I’ll provide all sensors, DAQ hardware, and cables. I need help:
1. Wiring the sensors to the DAQ
2. Setting up live plotting software on a PC
3. Verifying that the graphs update correctly during a motor speed sweep and that the data is recorded.

Want to build a new or utilize an existing drone, and make it fly autonomously indoor on a schedule basis, and capture a series of pictures and upload them to the cloud.

More details about the project to be discussed.
