Now that you have made a robot go forwards, you are probably thinking, \”well wouldn\’t it be great if I could make the motors turn backwards somehow?\” There is! Remember the part of the move steering block that controls speed? All we have to do is put a minus sign \”-\” in front of the speed button to make the motors spin backwards. The minus sign is right by the number 0 on your keyboard.
See what this looks like? So typing 40 means the motors will rotate forwards at a speed of 40. Typing -40 means the motors will rotate backwards at a speed of 40.
In the video, how many different directions did the robot go? (tap the box and enter the number)CorrectIncorrect
When the robot moves forwards its wheels rotate forward because the motors turn forward. Which way do the wheels and motors turn when the robot goes backwards?CorrectIncorrect
