The 2022 FIRST Robotics Competition game, Rapid React presented by The Boeing Company, challenged teams to simulate efficient cargo transport. Alliances of three robots scored points by collecting and launching inflatable balls—called cargo—into a central hub. The match began with a 15-second autonomous period, followed by a teleoperated phase where drivers controlled their robots to continue scoring cargo. In the endgame, robots climbed a series of ascending bars in their hangar, with higher climbs earning more points. The game highlighted themes of speed, logistics, and resilient infrastructure, tying into global goals for sustainable development.
To acquire the cargo we placed mecanum wheels onto a hex shaft. When the shaft spins, the mecanum wheels direct the cargo into the center, two rubber wheels stabilize the ball into the indexer.
The indexer holds and sends the cargo through with two pulleys on either side. There are sensors to tell the program to stop the motor from sending the ball straight into the shooter.
Once the robot is positioned the driver can start the motor controlling the hex shaft. Two rubber wheels grip the ball and send it out at a 70 degree angle to be shot into the upper hub.
The climb can acquire 4 to 16 points. We have a stationary arm which can grab onto the mid rung of the hangar, then a moving arm to traverse the robot to the high rung. We changed our original design because of the complexity.
