Bipedal Operations Bot
Skills : Altium, EAGLE, Embedded Software, C, Arduino ESP25,
- I developed environment maps using sensor data for a Bipedal Operations Robot, significantly reducing path planning time from 10 minutes to 2 minutes through the implementation of A* search compared to previous methods.
- Additionally, I designed a series of interconnected circuits on a protoboard, incorporating microcontrollers (Arduino/ESP32) to control motors and accelerometer sensors, which provided balance feedback and reduced signal processing latency from 500ms to 300ms.
- Utilizing PCB CAD, I created a custom breakout shield that interfaced with pressure sensors, motor controllers, an IMU, and a power and battery management system, ensuring seamless hardware integration. I also integrated a 4000mAh rechargeable Li-ion battery to power the motors, sensors, and control unit, extending the operational time from 3 hours to 4 hours while optimizing power efficiency and reducing battery drain by 1.5W during active tasks. Furthermore, I installed a wide-angle front-facing camera, connected to a Raspberry Pi, for real-time visual input, enabling object detection and obstacle avoidance using OpenCV for computer vision.
