What is the sketch tool used for?
Used to create 2d designs to be used later for 3d designs.
100
What is this thing called?
Expansion Hub
100
How long is the autonomous period?
30 seconds
100
What is an autonomous program?
moves by itself, no human control
200
What is the extrude tool used for?
Used for creating, adding to, subtracting from, or intersecting parts from sketches (by making the 2d sketches 3d objects).
200
What is a drivetrain?
Configurations of two or more motors with tank treads or wheels. Moves the robot in two or four directions, and steers the robot to both sides.
200
How many points do you get from scoring a freight in the shared shipping hub?
4 points
200
What unit does the encoder record the position of the motor shaft as?
tick
300
What is a pulley?
a wheel on an axle that is designed to support the movement of a cable or belt along its circumference, usually used to lift things
300
How many people are the drive team during competitions?
3 people (2 drivers, 1 coach)
300
List 2 encoder run modes.
STOP_AND_RESET_ENCODER, RUN_TO_POSITION, RUN_USING_ENCODER, etc.
400
List two examples of structural parts.
u-channel, quad block mount, standoffs, etc.
400
How many points are subtracted in a major penalty?
30 points
400
Why do we use encoders?
Setting the motor power does not create a fixed voltage or current since the battery is not always at a certain voltage. Lower battery output = lower motor output.
500
Why does a lower rpm motor have more torque?
Since higher rpm motors spin faster, each rotation is less torque so lower rpm motors have less rotation and thus, have more torque per rotation.
500
What are the maximum dimensions for the team shipping element?
4 x 4 x 8 inches
500
How do you convert ticks to distance?
Take the number of ticks per rotation of the wheel and divide it by the circumference of the wheel. Then multiply it by the target distance.
