Figure3–Motorwheels
The robot has 4 motor wheels with the same configuration. Each wheel is composed by
a motor block and a detachable wheel. The motor block has a 250W 8 poles brushless
motor with Hall Effect sensor and a reduction gear box, all hold by an aluminum cover.
These kinds of motors have a much longer life expectancy and a higher efficiency than
brushedmotors.
This kind of rubber tire is specially made for Robotnik, so contact us if you need to
replace them. It has a width of 145mm and a diameter of 235mm. The motor block
diameter is 100mm. It is recommended that no weight rests on the wheels for a very

The cable must be kept in good condition, and protected if the external cover is
damaged. There are three 24V power wires, two 5VDC power and three Hall Effect
signals.Iftheyareshortcircuit,themotorandthedrivercanbedamaged.
