1 Robotics Starter: Quiz Review
You need: pencil Discuss with your partner/table: What does each parameter in the Move Steering Block do? If you know how far a tribot travels with a given Move Steering Block duration, what are the steps in calculating the new duration for another distance?

2 Moving Straight Objectives: Students will be able to:
Write an EV3-G program for a robot to move straight Control the straight movement of a robot through the EV3-G Move block parameters Explain the role of each parameter in the Move and Motor blocks Calculate the required Move and Motor block parameters for a desired movement

3 Robotics Starter: Quiz Review Answer
You need: pencil What does each parameter in the Move Steering Block do? Ports that motors are plugged into Move steering command Turn motors on for # of Rotations, degrees, or seconds Brake or Coast Move straight forward How many rotations Power of motor

4 Do the Math In Rotations In Degrees
What are the steps in calculating the new duration for another distance? In Rotations In Degrees

5 RoboStarter 1 You need: pencil, laptop, EV3 Kits Discuss with your partner/table: Why is controlling a Move Steering Block duration with time tricky? What is the difference between controlling a Move Steering Block duration with rotations or degrees? When might you use one over the other? How would a tribot behave with each of these blocks?

6 Moving Straight with RoboMath: 1
Discuss with your partner/table: Ziffle’s Tribot required 1.3 rotations to travel 25cm. How many rotations must Ziffle program in his Move Block duration for his Tribot to travel 75cm? Scale Factor 1.3 rotations 25 cm x rotations 75 cm = Scale Factor x = 1.3 rotation x 3 x = 3.9 rotations 75 cm 25 cm Scale Factor = = 3

7 Moving Straight with RoboMath: 2
Discuss with your partner/table: Ziffle’s Tribot required 520 degrees to travel 25cm. How many rotations must Ziffle program in his Move Block duration for his Tribot to travel 62.5cm? Scale Factor 520 degrees 25 cm x degrees 62.5 cm = Scale Factor x = 520 degrees x 2.5 x = 1,300 degrees 62.5 cm 25 cm Scale Factor = = 2.5
