Answer Key: Unit Quiz

  1. The tribot will continue to follow the edge of the line for the specified length of time.  Knowing the speed of the tribot will allow you to control the distance the line followers travels by controlling the length of time the line-follower Loop runs.
  2. Sensor and Logic inputs can both control the Loop, or it can be set to run forever
  3. The Switch block is controlled by the Color Sensor.  If the sensor sees "not Black" the tribot turns toward the line, and if the sensor sees “Black” the tribot turns off the line.
  4. The True (Upper) Move Steering block Steering control needs to be set to steer the tribot slightly to the left and the False (Lower) Move Steering block Steering Control needs to be set to steer the tribot slightly to the right. Also, both Move Steering blocks need to be set to 'ON'.
