Another night of machining produced the wheel hubs, which will interface our Maxon drive motors with our spun aluminum wheels from Toledo Metal Spinning. They will work in conjunction with a ball bearing, to further support the wheels, and a lip seal to help protect the motor and bearing from dust and water ingress. These represent a significant step in the rover fabrication timeline because they are the largest turned part on the rover. We expect to be machining all day tomorrow, producing the three main components of the suspension bearing assembly. Some additional photos of the manufacturing process of these components have been posted to the WPI Rover Flickr (click on the sidebar on the main page).
