Wiring and Interface Notes
Always connect the wheel’s DC motor to a motor driver (like L298N or L293D) that supports the motor’s voltage and current. Use separate power supplies for the motor and logic, tying grounds together to avoid noise. For full omnidirectional control, mount four omniwheels with individual motors and set up a holonomic kinematics sketch on your microcontroller.
Frequently Asked Questions
How do I mount this omniwheel onto a DC motor shaft?
The 4 mm hub bore press‑fits directly onto a standard 4 mm motor shaft. Apply a small drop of cyanoacrylate glue to prevent slipping during heavy loads.
Can these omniwheels be used for true Mecanum drive?
Omniwheels have rollers perpendicular to the wheel axis, while Mecanum wheels use angled rollers. With four independently driven omniwheels you can achieve similar omnidirectional motion, though extremely precise strafing may require Mecanum wheels.
