What it can do

Written by Robotheca from the project's documents.

  • Four-wheel mecanum drive for forward, backward, strafe, diagonal and rotation movement, with each diagonal command driving two of the four motors.
  • Three-servo manipulator: arm sweeps smoothly between down and up, gripper opens and closes, basket flips to dump collected objects.
  • Driven wirelessly over Bluetooth with single-character commands from a phone controller app.
  • Built to clear debris and place water gel cubes in the Genie Firefighter game zones.

Wiring and electronics

Notes written by Robotheca from the project's documents.

Main parts

  • Arduino Nano microcontroller.
  • HC-05 Bluetooth module on a software serial port at 9600 baud.
  • Four 12V 50 RPM DC motors with mecanum wheels.
  • Two L298N dual H-bridge motor drivers.
  • Three high-torque metal gear servos.
  • 12V battery with a buck converter stepping down to 5V for logic and servos.

Connections

  • The HC-05 connects to the Arduino Nano through a software serial port.
  • The 12V battery supplies the motors, and a buck converter provides 5V for the logic and servos.
