Assembly 8 - Chain and Sprockets
Chain and sprockets are used to transmit rotational power from a motor to another part of the robot. During assembly sprockets are mounted on shafts and then chain is assembled onto these sprockets. Finally, the chain is tensioned. Build students will learn how to mount and secure sprockets, break chain, and use master links and half links to re-join chain on sprockets.
Assembly 9 - Belts and pulleys
Chain and sprockets are used to transmit rotational power from a motor to another part of the robot. During assembly pulleys are mounted on shafts and belts are assembled onto these pulleys. Unlike chain, belts are not broken and then re-joined, so assembling them with sufficient tension where a tensioner is not used requires the build student to learn the correct order of assembly and techniques to place belts into position.
Assembly 10 - Motors
Motors are a very common and powerful mechanism used in FRC robotics. Students will learn how to assemble planetary gear motors, and once they are assembled how to mount them onto the robot. They will also learn how to mount sprockets and pulleys onto the motors, or how to use shaft linkages to power longer shafts with motors.
