Example text

A motor is in stall (or is stalled) when it is commanded to turn but the shaft is blocked by some mechanical stop and is unable to move. This consumes a lot of battery power, and you should avoid this situation by, for example, turning the motor off before it gets stuck or removing the block that’s preventing the shaft from turning freely. The sensors give your robots the ability to touch and see. The Touch Sensor is basically a switch that your robot can use to detect contact with objects. The Color Sensor can measure ambient light, measure the amount of light reflected by objects, and recognize the color of objects.

Info ROV3R with wheels Y G These small caster wheels support the robot. They are passive, meaning that they don’t propel the robot but just follow the robot’s motion. Like shopping cart wheels, these wheels sometimes swivel when the robot reverses direction, causing the robot to jiggle. info The EV3 Brick has four output ports, labeled A, B, C, and D. Use the short cables to connect the right driving motor to port C and the left driving motor to port B. The ROV3R with Wheels is now complete. You can attach the modules in this chapter to this version of ROV3R or to the ROV3R with Treads.

The app sends a fixed amount of power to the motors on ports B and C, while it allows you to control the level of power for the motors attached to ports A and D independently. This will come in handy when you try to fine-tune the Line-Following ROV3R’s movements in Chapter 4. info front IR sensor The Front IR Sensor is now complete. The digital Infrared (IR) Sensor detects infrared light reflected from solid objects and receives commands from the Remote IR Beacon. The IR Sensor can be used in three modes: Proximity mode, Beacon mode, and Remote mode.
