Today we worked on just trying to get a finished and working robot. We assembled the second carriage, and the plates were also milled and attached. Rohan was milling the right angle brackets that interface with the chain, and Arusha tapped them with the tiny 4-40 tap. She broke one however; good thing we have extras! I think both the battery mounts were completed which is good. One issue was that the inner carriage has about 1/16 of play, which is a pretty big issue. We tried shortening the gab with some plastic taped to the elevator, but I think we will need to mill new plates to adapt and fix the issue.

It was a pretty light day as a lot of people had a good amount of homework due tomorrow. We worked on putting the finishing touches on the carriage, and should be able to mount it once the plates are done. The pistons from automation direct should arrive Monday and we should be able to fully test the robot. The main thing we need to figure out is how to mount the sprockets for the 2nd stage chain run. We will manual mill them tomorrow and hopefully install them. I worked with Chloe on mounting the chain to the first stage by measuring out the hole pattern then bolting it to the carriage. We then attached the 4-40 bolts to secure it to the chain. We also installed the elevator gearbox, which unfortunately will require some of the electrical parts to be relocated which is a pain.

Another day in the lab. We organized all the parts, wrote the part numbers on them, and marked them as completed or not on the robot spreadsheet. After misreading some of the parts, we sanded 4 2x1s wrong and will have to redo them tomorrow. The CNC is still pumping out the elevator parts, which is always exciting. The lathe was running once again and a lot more of the parts were created. The bellypan on one of the robots has to be redone since there was some metal caught in it so it didn’t make a secure hold. We should get our McMaster order tomorrow so we can really get some work done.

Today we worked more on CAD, finalizing the elevator mounting positions. In the lab we worked on mounting the PEM nuts for securely fastening the electronics and it is looking quite good. We started to put the gearboxes together, and ran into minor issues w/ clearance but it thankfully fits with some work. We need to get stuff ordered, a couple parts are holding up our assembly.
