With Hackaday Prize 2k18 deadline approaching, I'd like to recap what's been done during the month:

• Mechanics: base modeling is 90% finished. The aluminum base has been cut out, and small details like motor holders are already printed and fitted, but we still haven't figured out how to print the huge plastic dome atop the aluminum base that's housing the electronics.
• Electronics: the schematics is ready, soldering is postponed until the dome is ready, so that the assembly and soldering may happen in-place.
• Programming: it's been decided to reuse the existing firmware to the max, so this base will be compatible with Linorobot.

What's left to do:

• Mechanics: somehow splitting the huge dome and printing it, assembling the base and screwing on the electronics.
• Electronics: soldering the whole thing together according to the schematics.
• Programming: appropriating Linorobot firmware to make use of Arduino Mega's pin change interrupts to read encoder signals (2 encoders can be used with already existing, normal interrupt-based encoder library) and different model of IMU.
