The Robot
The 2020 French Cup of Robotic is a timed competition where two teams compete on a set that changes each year. 2020’s set is pirate themed and the robots are leaved on a beach-like scenery, where they have to sort and channel different pawn to specifics areas of the map.
The module we realized is used to help the robot understand where it is on the set. Those measurements are called “odometry”.


The circuit :

Amongst other components, to achieve sufficient odometry, we have
- A STM32
- A I2C bus to connect time of flight sensors to avoid colisions
- A MPU6050 (3 axis gyroscope and 3 axis accelerometer) also connected to the STM32 via a I2C bus.
- A PMW3901 optical sensor, much like ones you find below computer mouses.



We want to give a huge thanks to JLCPCB which helps us a lot during theses challenging times. They made the discussion very easy and helped us make this PCB in no time.
