Description: The HUB-ee is a type of robot servo but designed for wheels, in fact it is a wheel, but it is also a motor, a sensor and a motor controller. What’s that? Did we just blow your mind?

When you want to add wheels to your robot you would normally start with a whole collection of parts: The motor and gearbox, a motor driver board, and maybe some sensors for measuring wheel speed and a controller to count revolutions or provide closed loop speed control. Well, the folks over at Creative Robotics thought it would be handy if you could just buy a wheel that had all of those things built in, so they designed HUB-ee - just bolt it onto a chassis, apply power and away you go!

The HUB-ee is easy to mount, too! There are two threaded inserts for M3 bolts built in, there’s also a right angle bracket included for situations when you can’t go horizontal into the chassis. The mounting holes are even LEGO® lug compatible!! HUB-ee uses Micro-MaTch connectors to keep electrical connections tight and easily changed, check out the related items for mating connectors.
