5
10
15
20
Which of the following is the correct sequence of steps for the Robot Tractor Pull challenge?
Set your BaseBot in the center of the Field, download your project to your BaseBot, build a project in VEXcode IQ
Build your project in VEXcode IQ, attach your rope to your BaseBot, start your project
Download your project to the BaseBot, start your project, then attach the rope to your BaseBot and IQ Motion bin
Build your project in VEXcode IQ, download it to the BaseBot, attach your rope to the BaseBot and the IQ Motion Bin, set your BaseBot on the Field behind the second horizontal line, start your project
What is a gear train?
A type of VEX IQ robot
A mechanism made up of two or more gears
One gear that is moved to different places on a robot between builds
A type of force
Which of these configurations in a gear train would cause increased speed?
Two gears of the same size
A small gear driving a big gear
A big driving a small gear
Which of these configurations in a gear train would cause increased torque?
Two gears of the same size
A small gear driving a big gear
A big driving a small gear
Using gears for mechanical advantage allows us to multiply or reduce that amount of force without having to adjust the (a) force or change the direction of rotation.
Directional, speed
Speed, torque
Mechanical, electrical
Output, input

What is one way that a robot can be disqualified from the Tug of War Challenge?
A robot drives off the side of the Field.
A robot drives too fast.
Which of the following is the correct sequence of steps for the Tug of War Challenge Activity:
Choose a controller configuration, connect the two robots using the rope attachments; place them on a 1x3 Field with no walls; drive to see which robot flips the other robot first.
Check to be sure you downloaded the VEXcode IQ project to each robot Brain; connect the two robots using the rope attachments; place them on a 1x3 Field with no walls; add an addition to the robot; use the controller to drive the robots.
Choose a controller configuration, connect the two robots using the rope attachments; place them on a 1x3 Field with no walls; drive to see which robot pulls its opponent’s robot so that its front wheels touch the centerline of the field first.
