New Chest
In order to fit the RX-64 shoulders into BrainBot, we needed to design a new chest. Given the cost of printing the chest in one piece like we were doing before, we decided to make this new chest modular, with six sides (like a cube), and have everything screw together.
The new chest looks neat - we have a different 3D printer now, and it prints semi-transparent material. The tolerances are actually better than what the ABS printers do, although the material is not nearly as nice to machine or to tap. All in all, I'm pretty happy with how it turned out.
We also printed a gripper with this new printer. The structural parts of the gripper (specifically, the shaft and offset crank arm) are machined from aluminum and Delrin respectively. We use the foot pressure sensor board to provide feedback from four sensors on the grip.

Wow, these parts look great. I too am interested in 3d printing for robotics. I look forward to watching your work in the future, hopefully I can learn a thing or two. :) If it's possible, would you consider listing the prices you paid for parts? The Xardas site doesn't list the cost of the example parts they have on there.
