 There's 2 things that are really hard in CS - naming things, cache invalidation, and off by one errors. - Andrew Schreiber [more] |

Re: Encoders on mecanum drive?
It sounds like you've just been using encoders as odometers, rather than as elements in a closed-loop control system.
The typical use on a mecanum drivebase is to maintain highly detailed control over the wheels, to make the robot go in exactly the direction and at exactly the velocity desired. Each wheel is independenly driven with encoder feedback letting the speed controller update the voltage quickly in order to keep the wheel turning precisely as specified by the software. |
