How are Mecanum wheels controlled?

Every mecanum wheel has free rollers, which make a 45 degree angle with the wheel’s axis. Controlling the two wheels on one diagonal in the same direction and other two wheels in the opposite direction we get sideways movement as shown in the second figure (move right).

How does automatic 4 wheel drive work?

4-wheel drive auto functions by sending power only to the rear wheels until traction is lost. It engages the front wheels by activating an electric motor mounted on the transfer case which engages a metal fork that applies pressure to a set of friction plates inside the transfer case.

What is the biggest advantage of a Mecanum drive system?

The primary advantage to mecanum drive is the maneuverability it affords, especially because the robot can strafe instead of turn and drive. The rollers on mecanum wheels form a 45 degree angle with the wheel’s axis of rotation, which means that mecanum drivetrains can’t strafe as fast as they can drive forward.

How do you move Mecanum wheels?

In a mecanum drive, wheels are arranged similarly to a tank drive. This means that spinning all wheels forward or backward allows the robot to move forward and backward, and spinning the wheels on one side in the opposite direction of the other side allows for turning.

What are some advantages to a 4 Omni wheel design robot?

Allows all wheels to maintain ground contact while distributing the weight. Allows 4 wheel drive vehicle to translate at an angles/horizontally (holonomic motion). Often wheels can all turn in for point turns. All 4 wheels need to be actuated to spin and turn (often with 8 motors, but can be done with less).

How do I rotate Mecanum wheels?

To go sideways, the motors on the direction that one is trying to go in (in this case, right) rotate towards each other, and the wheels on the other side rotate away from each other.
