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?
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
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
Do the Math In Rotations In Degrees What are the steps in calculating the new duration for another distance? In Rotations In Degrees
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? 1 2 3
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
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
