RLS has been very kind to provide us with a set of rotary magnetic encoders. These encoders are something new and exciting, and are probably not something you’re used to. They work by utilizing Hall effect to sense angular position of a permanent magnet placed above the IC. (http://www.rls.si/products/rotary-magnetic-encoders)
Rotary encoders are going to be used for odometry (the use of the data from motion sensors for estimating the current position) which will enable the robot to know where it is on the playing field at any given moment. With that information, it can autonomously navigate itself to complete a certain task.
Be sure to check for an update, for when we integrate the sensors into our robot platform!
Once again, thanks RLS!
