Subsystems Flashcards
How would you describe the structural subsystem of the robot?
The structural subsystem is the skeleton, frame, chassis, or body of the robot.
What components make up the structural subsystem?
The structural subsystem is made up of the structural pieces, screws, nuts, threaded standoffs, pop rivets, and delrin bearings.
Are some of the structural components designed to be bent and/or cut?
Yes, several of the structural pieces are designed to be bent and/or cut?
Is there only one size screw in the VEX robotics kit?
No. There are several different sizes of screws in the robotics kit.
What is the advantage of using nylock nuts?
Nylock nuts have a plastic insert that prevent them from loosening due to vibration or movement.
What is the advantage of using KEPS nuts?
KEPS nuts have metal teeth on one side of them that grip the piece they are being installed on. This allows them to be installed without using a wrench.
What components make up the motion subsystem?
The motion subsystem is made up of everything that makes the robot move like the gears, square shafts, motors, and wheels.
What is the most fundamental component of the motion subsystem?
The square shaft is the most fundamental piece of the motion subsystem.
What is an actuator?
An actuator is something that causes a mechanical system to move.
Define the word torque.
Torque is the force with which the motor can turn the wheel.
Define the word speed.
Speed is the rate at which the motor can turn the wheel.
What converts the rotational motion of the motor to forward motion of the robot?
Wheels
What is the gear ratio in a system that has a driving gear with 36 teeth and a driven gear with 12 teeth?
1 : 3
What does an idler gear do?
An idler gear reverses the direction of rotation of the driven gear. It also doesn’t affect the gear ratio of the system.
When calculating a compound gear ratio, do you multiply or add the gear ratios of all gear pairs?
When calculating a compound gear ratio, you multiply the gear ratios of all gear pairs.
