Championship overview
The Mini Humanoid Robot Championship is a bipedal walking and obstacle-navigation competition and a flagship event of TechRadiance's National-Level Championship Series. Students assemble, program and fine-tune a 4 DOF biped humanoid robot on a standard 4-servo chassis, driven by an Arduino and fitted with an ultrasonic sensor.
Each robot competes individually and must run completely autonomously once its run begins, using its ultrasonic sensor to detect and react to obstacles. Success depends on servo calibration, gait programming, balance tuning and obstacle-detection logic.
Key highlights
- 500+ students and 100+ teams expected
- Certificate of Participation from TechRadiance, in association with E-Cell, IIT Delhi
- Prizes worth up to ₹10,00,000 for winning teams
- Fully autonomous, sensor-guided bipedal robots competing on walking, balance and obstacle avoidance
- Hands-on embedded systems and kinematics through robot assembly, programming and gait tuning
Two days, two levels of challenge
Day 1 tests walking, balance and choreography. Day 2 is an autonomous rescue mission.
Qualifying stage
- One biped robot per team, run individually on the track
- Teams use their own compliant robot built on the 4 DOF biped chassis kit (4 servos, Arduino, ultrasonic sensor), or an organizer-approved equivalent kit where applicable
- Up to two attempts; the better-scoring run counts
- The robot must stay upright and inside the boundary. After a fall it is reset at that point, with a penalty
- A penalty may be imposed for rule violations, unsafe operation or inappropriate conduct
Ranking: walk time and lane discipline, balance hold on each leg, dance creativity and stability, falls or resets, penalties, then a tie-break if required.
Rescue Mission: navigate, collect and deliver
- Finalists attempt the full mission as one timed run: Obstacle Navigation → Object Collection → Safe Delivery
- Clear all obstacles, collect the object and deliver it to the target zone in the shortest time
- Repeated falls, missed obstacles or a failed delivery can cost penalty points or the run
- Touching, repositioning or remote help during a run attracts penalties or run disqualification
The best mission score wins and progresses to the International Finale. Ties may go to a tie-break run.
| Straight-Line Walk | Walk a marked straight lane from start to finish in the shortest time with a stable gait. |
|---|---|
| Balance Zone | Balance on the left leg, then the right, holding each stance for a set time. |
| Dance Zone | Perform a short pre-programmed routine, judged on creativity, timing and stability. |
| Obstacle Navigation | Walk a track with obstacles, detecting and avoiding each one with the ultrasonic sensor. |
|---|---|
| Object Collection | Reach a set area and collect or push a lightweight object. |
| Safe Delivery | Carry the object to the target zone and release it inside the boundary in time. |

Robot specifications
Robots must be built strictly to these specifications.
| Chassis type | 4 DOF biped humanoid chassis kit: two legs, each with hip and ankle articulation |
|---|---|
| Actuators | 4 standard servo motors; replacement servos of equivalent torque and size are permitted |
| Controller | Arduino Uno / Nano or organizer-approved equivalent, as the only onboard controller |
| Sensing | One ultrasonic distance sensor (e.g. HC-SR04) for forward obstacle detection. Other guidance sensors are not permitted |
| Chassis size | Up to 25 cm high, 15 cm long and 15 cm wide |
| Control method | Fully autonomous; no remote control, Bluetooth/Wi-Fi or joystick during a run |
| Chassis material | Acrylic or 3D-printed body |
| Circuit assembly | Arduino shield or distribution/PCB board |
| Battery | Lithium, NiCad or dry cell, 6V to 12V |
Arena
A dedicated walking track on a flat, matte, non-reflective surface with clear boundary lines. Fixed obstacles, such as blocks or cones, are placed along it to test ultrasonic obstacle detection and avoidance.
Rules
Robot behaviour
- The robot must be fully autonomous. Wireless or remote control (Bluetooth/Wi-Fi) during a run is not permitted.
- It must detect obstacles using its onboard ultrasonic sensor only: no external guidance, GPS or pre-mapped coordinates.
- PID programming is not permitted.
- Servo range of motion and power draw must stay within the specified limits. Robots exceeding them may be disqualified.
Materials and construction
- Allowed robotic, mechanical and electronic components may be used, provided the robot meets all specifications and safety requirements.
- All materials must be safe, non-toxic and non-hazardous.
- No sharp, pointed, cutting or abrasive parts that could damage the track or another robot.
- The robot must be primarily the team's own build and program on the specified 4 DOF biped kit. Fully pre-assembled or pre-programmed humanoid robots are not permitted.
- Commercial components may be used individually within the team's own design.
Conduct and authority
- Judges and referees may disqualify any team whose robot or conduct is found to be unsafe or unfair.
- The organizers may modify any or all of these rules as necessary.
Team guidelines
- Bring everything you need: robots, laptop, chargers, cables, hardware, tools and batteries. Spares may be bought at the on-site desk, subject to stock.
- Teams have up to 5 members.
- Register online through the TechRadiance website.
- Have a robot ready, built as guided in TechRadiance workshops or to the published specifications, using the 4 DOF Biped Robot Chassis Kit.
Team video recognition
- Prepare a 1 to 5 minute video, maximum 100MB, showing readiness, creativity or enthusiasm.
- Share it at contact@techradiance.in (Google Drive or WeTransfer) or WhatsApp +91-7015568312 / +91-9667137548, with team and school name.
- Videos go on the TechRadiance Instagram page. The top 3 to 5 by likes receive a special recognition award.

A mini humanoid robot competition challenges students to build and program small two-legged robots that walk, balance and move like humans. Teams tune servos, gait and sensors so their robot can complete tasks on a marked track.
It is a fun, practical way for young learners to explore robotics, programming, kinematics and teamwork while competing with other young innovators.
