Eppur si muove

The one last thing I'd hoped to add to ThinBot for Robogames this year was motion, to swing the glass in and out from under the spout, making it easier to place a glass and pick up the finished drink.

I'm happy to report I got it working!

ThinBot progress -- two more pumps...

Last night I got pumps 9 and 10 wired and mounted. They will cantilever off the back of ThinBot's frame to be less obtrusive.

I also got a 5.5V current source wired up, on the off chance I get a servo for the arm installed and working.

I'm planning to put the whole shebang together tonight to make sure it all fits :-)

ThinBot progress

Today I made the nozzle jets for the heat exchanger. The final 2" is bent (electropolished=food-safe) stainless 1/8" OD tubing. This constriction at the end of the line (the rest is all 3/16" ID) should accelerate the ingredients into a set of streams that mix better in the glass.

I also got the glass-detection microswitch wired up and the code now recognizes it properly.

In addition, pigtails permitting two additional pumps have been wired in. The code has already been updated to make use of them if desired.

More machining -- new glass stand/rest

Today I finished milling the new glass stand for Thinbot, and test assembled it. I still have to wire up the switch and update the code to recognize it.

I probably don't have time to get it anodized before the show, but it looks pretty good in its natural silver.

Oh-- I also ran the pressure test on the heat exchanger now that it has had a chance for the sealant to cure. No drips after running it for an hour!

More Sneak Peakery...

I've made the first pass with the milling machine on the glass rest. It now has a slot to pass the stem of an up glass or other stemware.

I should get everything done on time. I also made a quick pair of small outrigger panels to hold two more pumps.
