 Their robot moves so fast that it changes colour due to the Dopler Effect. By rapidly alternating between driving away from the viewer (Redshift) and driving toward the viewer (Blueshift), they can make the viewer see it in their traditional purple colour. - philso [more] |

"Mini" 4-Claw Gripper Video
We designed a 4-claw gripper & fabricated it at 1:4 scale using a 3D printer. The test ball is a little large (7" instead of 6") but seems to work okay. http://youtu.be/FoE1ImP0pQI
A center poppet actuates the gripper fingers. We were hoping it could also launch the ball if we extended it rapidly, but full sized pneumatic tests were not encouraging. The cylinder travel was just too short.
