Semester 1- Exploration of Robotics (Units 5-7)

What robot component is shown in the image?

• Manipulator

• Servos

• Drivetrain

• Chassis

What robot part is shown in the picture?

• Drivetrain

• Manipulator

• Chassis

• Motor

What is the difference between torque and speed?

• Torque is the distance moved over time, and speed is the force of rotation

• Torque is the force of rotation, and speed is the distance moved over time

• Speed is a force, and torque is a distance

• Speed is determined by a gear train, and torque is not

What type of drive system do you think would be better for a robot to climb this hill?

• Wheels

• Tank treads

What gear is powered or moved directly by the motor?

• A

• B

What is the gear ratio for these two gears? Hint:  $Driven\ \div\ Driver$  

• 25:1

• 1:4

• 1:3

• 3:1

What is the formula for a gear ratio?

•  $\frac{Driver\ teeth}{Driven\ teeth}$  

•  $Driver\ teeth\ \times\ Driven\ teeth$  

•  $\frac{Driven\ teeth}{Driver\ teeth}$  

• Just guess...

Solve the gear ratio for the image. Hint:  $\frac{Driven}{Driver}$  

• 60:1

• 30:2

• 1:2

• 3:1

What is the result of using these two gears?

• High power

• High torque

• Balanced power & torque

What is a servo or servomotor?

• A small motor

• A motor which is accurate and only turns partially

• A motor used to drive machines by rotating

• A motor powered by electicity
