What is the difference between a gear and a sprocket?
Gears are meshed directly to one another; sprockets are used to hold chain or treads and do not mesh to each other

What is the difference between teleoperated, tethered, and autonomous control?
Teleoperated means remote-controlled; tethered means remote-controlled, but with a physical wire connecting the controller to the robot; autonomous means no remote control

What is the difference between an engineering technician and an engineering technologist?
Technician operates the tools/machinery/equipment used in an engineering field. The technologist repairs the equipment, performs maintenance, and makes sure the right tools are on hand.

List 3 things that gears or sprockets can do, in terms of motion. (Example: They can be used to transfer motion across large gaps)
Transfer motion across large gaps, change the direction of motion (clockwise/counter-clockwise), change the angle of motion (have two things spinning perpendicularly), adjust RPM, linear/angular speed, and torque.

What is a benefit to using a roller claw over a regular claw?
Roller claws will pick up the item faster; can be less accurate with driving/placing the claw

Give an appropriate TPI for cutting through wood, then another TPI for cutting through steel.
Wood: no more than 12 or 16; steel: no less than 24

If my wheel is spinning at 600 RPM, what is the resulting linear velocity (in ft/sec), if the wheel measures 0.5 feet in diameter? Leave your answer in terms of pi.
linear velocity = RPM / 60 * pi * diameter (in feet)
linear velocity = 600 / 60 * 0.5 * pi
linear velocity = 10 * 0.5 * pi
linear velocity = 5 pi feet/second
