This picture shows the playing field for the 2014-15 FIRST Tech Challenge competition, Cascade Effect. The robots need to knock out the kickstands of the central dispenser to release the balls, then pick them up and place them in the various tubes – taller tubes are worth more points.
Team Seuss works on its “giraffe neck” robot. The rules state that all robots need to start the competition fitting inside an 18-inch cube, so this robot has a ball conduit that starts out folded up and then unfolds into the configuration shown here. Once unfolded, rotating whiskers feed balls into the bottom of the tube and a conveyor belt carries them up the tube, disgorging them at the top to fall into the tall tubes.
