About HUB-ee Wheels

HUB-ee Wheels

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 all rolled into one.

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.

An idea!

We thought it would be handy if you could just buy a wheel that had all of those things build in so we set about designing one and the result is the HUB-ee - just bolt it onto a chassis, apply power and away you go!


Here are a few key features:

  • Removable 12mm gearmotor - available in a range of gear ratios (currently available 20:1 and 30:1)
  • Integrated, open source PCB with:
    • Motor driver IC
    • 32 stripe (128 counts per revolution) quadrature encoder
  • Designed for tyres or tank tracks
  • Two internal threaded inserts (metric M3 or imperial 4/40) make it easy to bolt on to a chassis.
  • LEGO® compatible mounting sockets

They are easy to take apart so you can remove or replace the motor or electronics. For more detailed information please visit the HUB-ee resources page.

Pronunciation? ... It's HUB as in wheel hub, with an ee as in e-mail.

Want to see HUB-ee wheels in action - check out these videos:


An Arduino™ Uno powered bot with IR rangefinders and all round tactile bumpers. (Yes - we plan to launch robot kits like this one soon, and our own range of shields for Arduino™)


Tankbot - Showing off how HUB-ee wheels can be used with tank tracks, and check out that ground clearance - that's what you get when you put the motor inside the wheel!


We decided to try out some extra powerful motors in our UnoBot chassis. The result - a very speedy bot!
The Arduino™ sketch is a little bit adaptive, the bot keeps track of sensor activity and ramps up the motor power if it thinks it is in an open space.
Still got some work to do on that stopping distance - those head on collisions hurt!


The HUB-ee wheel
The basic wheel, with and without the tyre - with the tyre it is 60mm in diameter and just 20mm wide.

HUB-ee with tank tracks
Without the tyre you can use it to drive tank tracks.

All the parts for a HUB-ee
An exploded HUB-ee. They can easily be stripped down and hacked, plus all the electronics are open source.

Basic machine comprising of a wheel

basic machine comprising of a wheel mounted inflexibly upon a hub or drum of littler distance across, the haggle pivot having a similar hub. It is on a very basic level a type of lever, the middle basic to both the haggle hub comparing to the support, the radii of the two sections to the arms. The exertion (connected to the wheel) expected to beat the resistance (following up on the pivot) is generally little. The mechanical preferred standpoint picked up by the utilization of the wheel is equivalent to the proportion of the span of the wheel to the sweep of the pivot. The haggle is not as effective as the lever, since a piece of the exertion must be utilized to beat the resistance of rubbing. In like manner utilize, a wrench or handle frequently replaces the wheel. of a wheel mounted inflexibly upon a hub or drum of littler distance across, the haggle pivot having a similar hub.

The haggle is a

The haggle is a straightforward machine. It comprises of a wheel that turns a pivot, or a hub that turns a wheel. It is additionally a lever that turns in circles around a point or support. The heap on the hub is all the more effectively moved in light of mechanical preferred standpoint. Dissertation Writing Help - Dissertation Club written the haggle can be thought to be a lever in which the range of the wheel is the exertion arm and the sweep of the pivot speaks to the resistance arm. It additionally is a solitary constrained machine. By changing the short separation of lifting, the drive is less on the grounds that the work dependably remains the same. A standout amongst the most well-known haggle is the wheel of an auto or truck.
