Drive System While the original drive system on the small robot was built, it was intended to be an extremely fast and mobile system to get around the field as fast as possible and pick up as many pile of game objects as it could. It was, however, slowed down and torqued up to suit the electrical engineering team’s needs. The newest design was made to suit the original purpose of the small robot, mainly due to the improvements made to the control code by the electrical engineering team. The drive was designed with four motors, each rotating at 100 RPM, driving a gearbox to gear up the speed 1:3 on omnidirectional wheels, giving a maximum possible speed of . Figure14 shows the initial construction of the chassis. Figure – Drive System for Worlds Small Robot Intake Device After the chassis was constructed, the initial concept for the intake was prototyped: a passive bar that flips up as it drives over a stack of game objects, and sucks them in as it drives past them. This was built to feed the game objects into an inner section that feeds the balls directly to the flywheel launcher. Figure 15 below shows this bar on the finished chassis. Figure – Passive Intake on Front of Chassis In order to build the rest of the intake, the flywheel had to be built and mounted; a vertical intake section was then built to raise the game objects from the floor and bottom section of the robot to the top. It was driven by two motors, each attached to a bevel gear to turn the shafts 90-degrees from the motors mounted orientation. The bevel gears drove a shaft that had a sprocket mounted on the end of it, which drives tank-treads with flaps mounted to it. Those flaps lift the game objects up about , and pushes them into the flywheel. Figure16 shows the top section of this intake. Figure – Hood on Worlds Small Robot
