project 05

Automated Commodity Futures Trading2016-2017


Maze Solving RobotSpring 2016


The course project of Science and Technology Innovation (Part 4-E) at SJTU. The project involves hardware design of a three-wheel mobile robot and software programming of the PSoC4 embedded controller. In the final, the robot was able to track a black line, autonomously navigate through a maze, estimate odometry accurately with encoder and inertial sensors and receive Bluetooth teleop commands to do complex maneuvers.
