The Yozh robot – using an ESP32-S3 programmed in CircuitPython #Robotics #CircuitPython @IslandRobotics

The Yozh robot was created to teach robotics class at a summer camp, SigmaCamp. Alexander Kirillov wanted something small, programmable in Python, and easy to extend.

Key features

  • Dimensions: Length: 12.4 cm; width: 13 cm; height: 4.8 cm
  •  Power: one or two 18650 Li-Ion batteries
  •  Wheels and motors: uses silicone tracks and 6V, HP, 75 gear ratio micro metal gearmotors, both by Pololu.
  •  Main controller: ESP32-S3 Feather board by Adafruit, which serves as robot brain. It is programmed by the user in CircuitPython, using a provided CircuitPython library. This library provides high-level commands such as move forward by 30cm
  •  Electronics: a custom electronics board, containing a secondary MCU (SAMD21) preprogrammed with firmware, which takes care of all low-level operations such as counting encoder pulses, controlling the motors using closed-loop PID algorithm to maintain constant speed, and more.
  •  Included sensors and other electronics
