0-FT-MECANUM-SET-V2 FingerTech Mecanum Wheels v2 (set of 4) <p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">Use the Mecanum Wheels to add omni-directional capabilities to your robot.</font></p>
<p><font color="cccccc" size="2" face="Arial, Helvetica, sans-serif">What can they do? </font><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif"><br />
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 degrees also allows the robot to translate sideways, and through a combination of movements, drive in any direction - even while spinning! </font></p>
<p><font color="cccccc" size="2" face="Arial, Helvetica, sans-serif">How do they work? </font><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif"><img src="http://www.robotmarketplace.com/products/images/0-FT-MECANUM-SET-V2_move.jpg" style="float:right;"><br />
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. </font></p>

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. </font></p>
<p><font color="00ff66" size="2" face="Arial, Helvetica, sans-serif">The Robot Logic <a href="RL-MECANUM.html">Mecanum Mixer</a> can 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!</font></p>

Testing a 1.36kg (3lb) Mecanum robot pushing against another unpowered robot equipped with Lite Flite wheels: <br />
Pushing Forward, the Mecanum robot easily moves 66% of its own weight and can slowly push 100%.<br />
Pushing Sideways, the Mecanum robot can easily move 33% of its own weight and can slowly push 66%.
