The Arduino GPS tracker circuit connects three main components: Arduino UNO R3, NEO-6M GPS module, and SIM800L GSM module. This design uses both hardware and software serial communication since ...

A DIY robot uses force sensors, servo motors, and Hooke’s Law to decode lock pins without a camera, reducing brute-force attempts from 100,000 to just 243 combinations.

Trajectory tracking for a differential drive robot is accomplished using Laguerre-based model predictive control. This paper emphasizes obstacle avoidance for the same robot using model predictive ...
