This one was a three axis KAOS robot pick and place with five meter per second (ludicrous speed, capable of it, but unnecessary), and (amazingly and unnecessarily) five nanometer resolution. Our customer's machine did not go into high production, but the robot worked great. Delta Tau made the coordinate system easy work. A single line in the config file was enough to make this kinematic accept Cartesian commands.
I'm embarking on an ornithopter project.
Rules for the playoff were:
90 seconds to set up and fire one shot into a reduced size hole
60 points for a swish
50 points for hitting the edge and in
30 points for bouncing off the top
Jocelyn accosted the director to make sure there would be a runoff for third against the two other teams that bounced the top.
Our team want on Friday To JPL for the finals. Here's video our first round, three successful shots putting us in a five way tie for first out of thirty teams!
A small group at San Marcos High is doing the JPL challenge; a machine that kicks a football into a trashcan 5m away, over a 2m barrier. I am enjoying advising the students on the project!

This is a set of ServoBelt stages stacked to be an XY for a semiconductor application. This video is just a burn-in move. The critical move of 12mm can be done in 180msec, settled to 5um. Payload is 34 lb. Motors are Teknic NEMA34 4-stack on the bottom and NEMA23 4-stack on the top, with Teknic Eclipse 350R amplifiers, and Renishaw RGH41 linear encoders.
A little closer view from the first push. Still need to take data, but I've got to travel for a bit. On close inspection, I see I need to dress the critical surfaces a bit for smoothest contact, so I'll take a quick data set, then clean it up. I may take it from .003" to .001" flexures while I'm at it.
