Humanoid Robot for Education
Budget: ₹12,500 – ₹37,500 INR
The goal is to create a humanoid-style mobile robot on a differential-drive wheeled base that can be taken straight into a classroom or university lab and used to demonstrate key robotics concepts. A front-mounted LED matrix will act as the “face”, giving the machine simple emotive expressions while also serving as a visual channel for status messages during demos.
Core learning objectives
• Motion control and navigation – smooth differential steering, basic path planning and PID speed regulation.
• Sensor integration and data processing – fusing inputs from wheel encoders, IMU and at least one range or vision sensor for obstacle detection.
• Human-robot interaction – expressive LED feedback, button or voice trigger for demo sequences, and safe stop behaviour.
The build should run on readily available hardware (Arduino, Raspberry Pi or comparable SBC+MCU pairing) and be coded in Python/C++ so students can edit and re-flash with minimal friction. ROS support is a plus but not mandatory if equivalent modular architecture is provided.
Deliverables
1. Fully assembled, tested prototype capable of the above functions.
2. All design files: CAD, wiring diagrams, STL or STEP for printed parts, and a complete BOM with sources.
3. Well-commented firmware / software, plus step-by-step instructions for flashing and calibration.
4. A short demo video that showcases motion control, sensor-based navigation and LED facial expressions in action.
5. Instructor notes outlining how to use the robot to teach the three focus areas.
Acceptance criteria
• Robot drives straight for 2 m, turns 90°, then returns within ±5 cm of start.
• At least one live sensor stream displayed or logged while the robot moves.
• LED face changes expression based on an external event (e.g., obstacle detected).
• All documentation clear enough for a graduate student to rebuild the unit without further guidance.
Once these items are delivered and verified, the project is complete and ready for the next cohort of budding roboticists.
We are seeking an experienced robotics/mechatronics freelancer or team to design, build, and deliver a functional Humanoid Wheeled Mobile Robot (WMR). The robot will feature a differential drive mechanism, a humanoid appearance (including a fixed head and hands), and a programmable LED matrix face capable of displaying 12 facial expressions.
