Minions in Mecanum Vehicles - Control Motors Synchronously
The Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction.
The Mecanum Wheel is based on a tireless wheel, with a series of rubberized external rollers obliquely attached to the whole circumference of its rim.
These rollers typically have an axis of rotation at 45° to the wheel plane and 45° to the axle line.
When spinning generates a propelling force perpendicular to the roller axle, which can be vectored into:
+ a longitudinal component
+ a transverse component
Minions use Pulse Width Modulation technology to adjust the speed of their vehicles.
Minions change the running direction of each wheel or motor with H-bridge technology and control the direction of their vehicles by combining different wheel directions.
Camellia Mini could control all motors synchronously, which keeps 4 Mecanum wheels changing direction or speed simultaneously, thus making the vehicle perform perfect omnidirectional running.
