MCM: Up and Running

After a rush of machining and assembly, we got our MCM up and running for MS8. Our car drives and turns well and the sweepers proved capable of collecting and holding balls. Some changes to the gearing and more traction on the drive wheels are needed to optimize performance, but even as it is right now I think it's safe to say our triumph is inevitable. Unfortunately, I didn't take any pictures until after we'd passed on the control system and begun modifications.

All of the engineering for our other modules (which focus on slot-play) is also done, and next week will be a flurry of activity as we work to machine and assemble those modules.

MCM Parts and Assembly

This week we got the last of our ordered parts in (including pulleys and belts for our sweeper system). After dealing with a few hiccups, we've fabricated just about every part needed for our MCM. Assembly has begun and we should be able to get our motors on and powered up at the beginning of next week. After that we'll be able to move on to our other modules.

Things are starting to come together:



First Week of Fabrication

After making some changes to our module designs, we finally got to hit the machine shop this week. Everyone's been able to get in throughout the day and we've got a lot of finished parts to show for our effort.

So far we've used most of the machines (lathe, mill, band saw, arbor press) and mulitple processes (turning, cutting, drilling, pressing, threading). Some of the parts we've ordered have started coming in, and as soon as we get the rest and some more raw materials we'll be able to fabricate the last of our MCM parts. Barring a lack of materials, we should be able to start assembling the module early next week. By the end of the week we should have moved on to fine tuning and fabricating the next modules.
