We have one session left, and I hope to use that mostly for test driving. All components have been built, successfully tested, and in one or two instances broken. This is all good, as we have just enough time to fix things, and it is our failures that teach us the most.
Main work today was on the arms. One dispenses M & Ms, the other deploys a water squirter. I thought long and hard about how best to do these mechanically, but in the end the engineering issues seem to have solved themselves.
The other arm contains a water squirter. We have a faster actuator there, a smaller one from a satellite dish controller. Here is some rather lousy film of it in action. I have a bad habit of not holding the camera in the correct orientation for this...
The swivel device is less robust than we thought. There were a couple of lag bolts not put in far enough, allowing some rocking. This is not good, as a little more loosening could cause the whole top half to pitch forward. A kludge solution should take about half an hour.
And we need to figure out to set the controls to most ergonomically control the golem. It will take two students each with their own radio controller. One will operate the bottom half, drive and swivel. The other gets the top half with left and right arms, the squirt cannon and the M & M dispenser. I wonder which assignment will be more in demand?
A view of the near finished product, only the M & M dispenser is out of view. We have it up as high as possible to get more gravity feed.
