I’ve got some wheels for the Android Robot I’m working on. Had to find some wheels directly driven from modified servo’s. Lego Technic to the rescue:

Van Drop Box

These come off a Lego Technic set with number 8479, the green scanner truck for those who are familiar with Lego (who isn’t :)). You can buy the tires separatly and they also have the rims. You can look for a shop closer using the product numbers on this website.

The servo horn I used ships with the 9g servo’s. They fit exactly inside this wheel. I used some tie wraps to keep it in place.

Now I’ll be looking for some platform to attach these wheels to.
