A lightweight, mini Mecanum Wheels robot that is small enough that it can be printed on nearly every 3D printer. All of the parts snap into place and no tools are required for assembly.

Recommended Print Settings

• 1.2mm vertical shell thickness (2 x 0.6mm or 3 x 0.4mm perimeters, etc)

Control Software

This Mecanum Wheels Robot can be easily controlled with PestoLink from AlfredoSystems. Once PestoLink has connected to the XRP a gamepad can be used to control the bot.
