wheel hub

LEO the Arduino Compatible robot

Hi Lets Make Robots,

We have a robot kit on Kickstarter that we think people might like. It is the first kit we designed that makes use of our HUB-ee wheel hub motors (which you can already get from places like Sparkfun and Robotshop.com)

Re-inventing the robot wheel

Anyone wanting to play with articulated robotic systems like arms, legs, pan tilt cameras etc will invariably end up using the ubiquitous hobby servo, a handy little gear motor that comes with its own angle sensor and closed loop position control. You just plug them in, send a position pulse and away you go. You can even hack them to produce continuous rotation for wheeled platforms, albeit without any closed loop control.

Couplings or wheel hubs for cordless drill motors

I posted some design info and pictures of a robot I'm working on to the main LMR robots listing. You can check it out here

As I indicated in the post, however, I'm having trouble coupling or interfacing some cordless drill motors (the Harbor Freight 17v kind which I have read many people use in their bots) to some 1/4" screws, which are the axels of the wheels on my robot.
