Abstract: "I programmed me" and tethered quad copters
Inspiration: A post I saw today, and Short Circuit
Description:
  • A robot starts in the area between the Auto Zone and Landfill.
  • As autonomous begins, it launches four tethered quadcopters to go snag the four RCs on the step, using passive "claws" attached to the underside of each 'copter.
  • (Note that all 16 breakers are being used, since a quadcopter requires 4 independent motors!) The 'copters carry the RCs into the auto zone.
  • Three of the 'copters then proceed to the staging areas to bring a tote back, stacks them, and returns. The fourth flies back to the main chassis.
  • All of this is coordinated by cameras on the "mother ship," which simultaneously rumbles along a three-foot trek into the auto zone powered by rotary pneumatic actuators.
  • As each 'copter returns from delivering its payload, it lands in its launch bay, which triggers a series of servos that pull out some Anderson connectors and push in others.
  • Other servos do the same with breakers, as we have switched to larger wires that don't have to serve as tethers.
  • One quadcopter is kept in service to do "noodle duty", which it performs not at the HP station, but by snagging noodles thrown over the alliance wall.
  • Any that it perceives will not make it into the opposing alliance's work area are snagged and stuffed into an RC.
  • Meanwhile, in the first 60 seconds of tele-op, the main robot (which has two lifts, one optimized for upright totes, the other optimized for inverted totes) has quickly cleared the landfill and step of totes, and stacked them on the back scoring platform, topping them with noodled RCs.
  • In the latter 75 seconds, it picks up any totes from the HP station that its alliance partners couldn't get, and stacks them as well.
