100

This kind of mechanism takes advantage of the concept of a parallelogram, where opposing sides will always stay parallel no matter the angle. 

What is a four-bar mechanism? 

100

This is the size of all hex shafts we use in our builds. 

What is a half inch (1/2")? 

100

This cloud-based software is the platform we use to create all of our 3D CAD designs on 4272. 

What is Onshape? 

100

This round component allows a shaft or other long item to rotate in a hole with very little friction. 

What is a bearing? 

200

This mechanism allows for vertical linear motion and can be used in conjunction with many kinds of end effectors. 

What is an elevator? 

200

This size of bolt fits into a clearance hole with a 0.201" diameter. 

What is a #10-32 bolt?

This popular online FIRST Robotics forum is a place where you can go to see what other teams are doing and read advice teams give each other on robot design, team activities, awards judging, and more. 

What is Chief Delphi? 

300

This measure of rotational force is given by the formula _____ = r * F. 

What is Torque (T)? 

300

This broad category is used to describe any mechanism that launches a (usually round) game piece from the robot using high-speed wheels. 

What is a flywheel shooter? 

300

This is the outer/hole diameter for a flanged bearing that takes a half-inch (1/2") hex shaft. 

What is 1.125" (one and one-eighth inches)? 

300

This website is where our team uploads instructional videos to help teach our students and other teams important robot-related concepts. 

What is YouTube? 

400

This level of gear ratio (high/low) is better for use in high-torque, lower-speed applications. 

What is a high/large gear ratio? 

400

This mechanism often requires a high gear ratio due to its length and use in reaching outside of the robot. 

What is an arm? 

400

This is the pitch of an HTD belt. 

What is 5mm (five millimeters)?
