Mecanum Wheel 4 Pack (w/ Metal Hubs)
Description
What can they do?
The four Mecanum wheels are each connected to a separate motor with independent control. The robot
can move forward, backward and turn just like it would with four regular wheels. The configuration of
rollers at 45° also allows the robot to translate sideways, and through a combination of movements,
drive in any direction - even while spinning.
How do they work?
Adjacent corners of the robot use mirrored wheels so that they can freely roll outward from the center.
This splits the force into two vectors, one forward/backward and one right/left. When the wheels on
one side are spun in opposite directions, the forward and backward vectors cancel out while both
sideways vectors add up. Doing the reverse with the other two wheels results in four added sideways
vectors.
How do I drive?
Control can be accomplished with a microcontroller or simply using an R/C transmitter! You can use two
channel mixers, a 4-channel Mecanum drive mixer, or your own programmed PCB.
The guys over at Robot Logic have put together an R/C Mixer for Mecanum Wheels. Now control your
omni-directional robot with just 3 channels of your transmitter! The right stick is used for translation
left/right/forward/back while the left stick is used to spin the robot. This gives you a super simple
method of driving your robot! Combine this with a heading-lock gyro (common in R/C helicopters) for
rock-solid operation.
