Notes and code for Mr Massey's Mecanumbot

---

The mecanumbot is a Nexus 4WD 60mm Mecanum Wheel Robot Kit.

Features:

• four DC motors with encoders and 60mm mecanum wheels
• Nexus' Arduino Uno/Nano/?? (atmega 328p) board
• Nexus' Arduino I/O Expansion board
• big red button

---

Useful documents:

• Overview PDF - product overview, specifications, useful mecanum wheel diagrams.
• Reference PDF - instructions (sometimes confusing).

I've opted for writing code for this myself rather than using their library, since it seems a bit over the top and I actually couldn't find an official copy anywhere.

Code:

• Basic movement
  • code moves the robot in a circle
  • comments cover the basics of wiring up the boards to control the motors
