What it does

  • Drives brushed DC motors through PWM using common full-bridge driver ICs such as the L298 and TB6612.
  • Optional encoder and photo-interrupter support enables driving a specified distance.
  • Controls two motors at once for robot cars, including turning and rotation by degrees.
  • Per-motor speed compensation values can offset differences between motor characteristics.
  • Supports mecanum four-wheel car movements with extended directions.
  • Includes example sketches such as line following, IR remote control and obstacle avoidance.

Getting started

Difficulty
Beginner
Hardware it needs, as the project states it
Arduino-compatible board with brushed DC motors and a full-bridge driver such as L298 or TB6612 (or an Adafruit Motor Shield V2); optional encoder discs with slot-type photo interrupters and an MPU6050 IMU, plus TCRT 5000 or IR/ultrasonic sensors for the examples.

Robots that can run it

No robot on Robotheca is linked to it yet. Links come from a robot's robot.yaml, from its dependency files read as text, or from Robotheca's editors.

Robotheca lists software as a reference: nothing is hosted or run here, and every fact links to where it was read.
