Re: pic: Team 73 2007
Greg, can you tell us a bit about your elevator and wrist setup? The elevator looks like a continuous cable pulling on 3 stages. Fabrication seems to be box aluminum with some custom bearings?
The wrist (shown in your previous teaser ![]() If you put a little orange on that 'bot, I'd say that you copied our design. Or, if our's was blue, vice-versa! Excellent looking 'bot, I hope to get a chance to watch it this year! BEN |

Ben you are close... but I will enlighten you further. The elevator is 45mm Bosch extrusion which is a cascading cable system with the first stage driven by chain (there are actually 6 different cable sections which enable driven motion up and down). The end effector has a wrist (yes that was the teaser) driven by a globe motor on a ~3:1 reduction via chain over a dead axle. The 90 deg rotation of the arm upwards is driven by a globe motor directly driving the axle of the gripper. The grabbing mechanism is driven by a pneumatic cylinder completely mounted within the gripper. All in all it gives us 4 axis of motion on the arm and 5 degrees of freedom when you count the drive train. These are some other photos of the mechanism from a week or so before ship but it will give a better view of the arm. http://www.team73.org/ideas/2_11_07d.jpg http://www.team73.org/ideas/2_11_07b.jpg http://www.team73.org/ideas/2_11_07c.jpg http://www.team73.org/ideas/2_13_07c.JPG Last edited by Greg Needel : 02-22-2007 at 10:31 AM. Reason: figured it was better with the images not imbeded. |
