The JSumo HyperLine Robotics (HLR) V3 is an advanced, high-speed line follower robot built for competitions. This version is the result of 3 years of prototyping, optimizing both speed and precision without relying on external downforce like an EDF or impeller. As a member of the JSumo Team, I have combined lightweight engineering, high-speed motors, and custom-built sensors and chassis to achieve high performance.
- No additional downforce – Traditional high-speed line followers use EDFs to generate downforce, but HyperLine Robotics V3 achieves comparable speeds without any additional generated weight, based on comparisons with a 300g EDF-powered robot (V2).
- Ultra-lightweight design – The robot is engineered to be significantly light, ensuring agile movements and optimized acceleration.
- Custom 16-sensor array – Precision-designed for maximum accuracy, this sensor array system ensures fast detection of the track at all speeds, by using it with our public library.
- Optimized PCB chassis – The chassis PCB integrates all components efficiently, reducing weight and improving weight balance.
- Lightweight carbon fiber bars & FPC cables – The 2mm carbon fiber bars and FPC (Flexible Printed Circuit) cable are used to connect the sensors to main PCB chassis, reducing weight while maintaining structural integrity.
- Custom-built motor mounts & wheels – The motor mounts and wheel rims are custom-manufactured from 3D printed using CF PLA (Carbon Fiber PLA) for improved durability.
HyperLine Robotics V3 is engineered to maintain top speeds comparable to a 300g robot with EDF downforce, yet it remains significantly lighter at around 100g. The key innovation lies in:
- Optimized weight distribution – Eliminating unnecessary materials while maintaining structural integrity.
- High-efficiency silicone wheels – Ensuring superior grip without extra weight.
- Advanced motor tuning – Maximizing power output without requiring additional stabilization, while minimizing vibrations.
One of the standout features of HLR V3 is its custom-designed sensor array, which drastically improves track detection accuracy:
- 16 individual sensors for high-resolution tracking.
- Custom Multiplexer Integration – Reducing processing overhead and increasing reaction speed.
- Adaptive Calibration – Ensuring maximum reliability across different competition conditions.
- Custom sensor development – Full details and design can be found in the my official repository: Line Follower 16-Sensors Bar with Multiplexor

With these innovations, HyperLine Robotics V3 has achieved performance levels comparable to heavier EDF-powered robots. The perfect balance of speed, weight, and precision allows it to compete.
HyperLine Robotics V3 will be competing in the Robotics Championship 13th Edition, taking place from May 15 - 17, 2025. This event serves as the test for its capabilities before the InfoMatrix Final the following week. Additionally, I will introduce an innovative lightweight impeller-powered robot, HLR V4, expected to reach 4605+mm/sec on average per lap.
