Hmmm. Define robot. [BINGO!] I'll leave out BoeBots, Roombas, Summer half-scale games, and other sub-FRC scale and/or COTS robots, but count FRC (and slightly larger) scale robots that we designed and built whether or not they were ever intended to be FRC legal.
From the middle of February to late May 2016, we had four FRC+ scale robots working most of the time:
- T1GGR, 2016 competition robot
- R00, 2016 practice robot (built to be FRC legal - a clone of T1GGR)
- Atlas, 2015 competition robot
- Ugly Betty, Air Cannon, (Arduino controlled, has two batteries and a scuba tank, possibly overweight as well)
In late May, after we lost most of our build and storage space, we broke Atlas down to an omni kit chassis with drive train but no control board. We may have gotten back up to four briefly last month when we got Peabody's chassis (2015 practice robot) working as a pneumatically-actuated slide/H drive, and we got Betty working in umbilical (massive tether) mode. In the last two weeks, we have moved one of the roboRIOs (not sure if R00 or Peabody) to control Ugly Betty, as we were having difficulties with the xBee-Arduino interface on Betty.
