In this lesson, you’ll learn about gears and how they’re used in robotics. We’ll cover how gears control a robot’s speed and power, helping you build more efficient designs.
Which of these statements about gears is true? A gear train can increase both speed and torque at the same time. If you increase the speed of a gear train, you will decrease its torque. If you increase the torque of a gear train, you will also increase its speed. A gear train can only increase speed, not torque. A team wants to build a robot that can push a heavy object. Which gear setup would be the best for this task? A small driver gear with a large driven gear. A large driver gear with a small driven gear. Two gears of the same size. A worm gear turning a small spur gear. Why is it important to know the difference between a driver gear and a driven gear? The driver gear is always bigger than the driven gear. The driven gear is the one that's connected to the motor. The driver gear is the input, and the driven gear is the output. The driven gear is the only one that can turn. Which type of gear is best for changing the direction of motion, such as making a vertical motor power a horizontal wheel? Spur gears. Worm gears. Conical Gears. Tabletop gears. A simple program makes a robot drive forward for a set amount of time. If you use a gear train to increase the robot's speed, what will happen when you run the same program? The robot will move a shorter distance. The robot will move the same distance. The robot will move a farther distance. The robot will stop after a few seconds.
