Manufacturing II

Shown here is an example of the typical manufacturing process for one section of the robot. Omitted is the first stage of this component (in this case the rear base of the robot) , in which several machining operations were done. Some components require machining on both sides, and this usually requires the use of fixtures and "clocking" to ensure accuracy, a very time-consuming process.

In this case, a profile of the component is machined in to a wooden "jig", and the component is then re-placed on the profile. This ensures absolute accuracy (taking into account the repeatability of the machine), and does not requiring clocking or fixtures.

The centre image shows a "roughing" machining procedure. At bottom is the completed component (top) as well as two other robot frame components.

Manufacturing

Here is the revised design for one of the frame sections. Shown in the picture are weight-reducing features, as well as a section machined out for one of the PC104's dual cooling fans.
