Robotics Midterm Review

Mechanical Advantage

• A measure of the ratio of output force to input force in a system.

• A method to increase the speed of a machine.

• The total energy output of a mechanical system.

• The distance over which a force is applied.

Motor Group

• Consists of two motors that are going to function as if they are one device.

• Is a single motor that operates independently.

• Includes multiple motors that work in isolation.

• Refers to a group of motors that are not connected.

Tank Drive

• Each joystick controls the robot in the forward and reverse direction. Thus, to turn, one joystick will go forward and the other will go in reverse.

• Both joysticks must move in the same direction to turn the robot.

• The robot can only move in a straight line with tank drive.

• Tank drive allows for diagonal movement of the robot.

Drivetrain

• A mechanism that consists of two or more motors, and wheels, that make a robot move.

• A system that controls the speed of a robot's movements.

• A type of sensor used to detect obstacles in a robot's path.

• A software program that manages a robot's tasks.

Claw

• A type of gripper that is used to pick up and transport objects.

• A tool used for digging in the ground.

• A type of animal foot with sharp nails.

• A device for measuring temperature.

Balloon Tires

• Wider tires that have a smooth rubber surface with no tread.

• Narrow tires designed for high-speed performance.

• Tires with deep treads for off-road use.

• Standard tires with a mix of rubber and metal components.

Pendulum

• A body suspended from a fixed point so that it can swing back and forth under the influence of gravity.

• A device used to measure time based on the flow of sand.

• A type of clock that uses water to keep time.

• A structure that holds weights to balance forces in engineering.

Right Arcade

• Control the robot completely using the right joystick on the controller.

• Control the robot using the left joystick on the controller.

• Control the robot using voice commands.

• Control the robot with a mobile app.

Friction

• The force that resists motion through the rubbing of one object against another.

• The force that accelerates an object in motion.

• The force that pulls objects towards the center of the Earth.

• The force that allows objects to float on water.

Traction

• The force that makes an object move by pushing against a surface.

• A type of friction that prevents slipping.

• The weight of an object acting downwards.

• The speed at which an object moves in a straight line.
