Part 3 - Robot Design

What types of engineers work together to design robots?

• electrical, petroleum, and civil

• electrical, mechanical, and chemical

• electrical, software, and mechanical

• electrical, aerospace, and packaging

Motors/Arms: Which formula is used to calculate the torque required to lift objects?

• Work/time

• Force x distance

• PSI x GPM/1714

Force directed in a circle (a spinning force) is known as?

• Speed

• Torque

• Acceleration

• Velocity

Motor/Arm: The more torque the robot has, the more force it exerts on the object, and the faster the arm will lift it up.

• True

• False

Motor/Arm: A robot has limited torque at its arm joint lifting objects of different weights.  How does this affect the required arm torque?

• a shorter arm will be able to lift more weight than a long arm

• as the weight of the object goes down, the torque required goes down as well

• heavier objects require more torque to lift

• All are True

A robot’s work depends its task, which intake method is great for single object grasping? (often utilize in object picking, placing and/or packaging)

• Arm & Claw

• Fork & Shovels

• Bumper & Rollers

• Wheels & Continuous Tracks

A robot’s work depends its task, which intake method has a top or side configuration? (often utilized in material pushing, sliding, pressing, or smoothing)

• Arm & Claw

• Fork & Shovels

• Bumper & Rollers

• Wheels & Continuous Tracks

When an application requires more power than a motor can handle, a designer has which option?

• Change the gear ratio

• Switch to a more powerful motor

• Use more than one motor in the application

• All of the Above

Which of the following is true for a Raised Chassis?

• front wheels should be low friction

• there will be even power to all wheels

• can strafe side to side easily

• raises the center of gravity

Which of the following is true for a Rear Powered Chassis?

• front wheels should be low friction

• there will be even power to all wheels

• can strafe side to side easily

• raises the center of gravity
