Question
The circuit diagram below is for a robot that walks around the room. It is designed to stop walking when certain conditions are met. Praximity Sensor ON = cose to wal OFF = far from wal Battery Status ON = good OFF = low battery Light Sensor ON = room ights on OFF = room ights f Output ON = Robot waks OFF Robot stops Complete the truth table for this circuit. Proximity Battery Status Light sensor Output Sensor 1 1 1 1 1 1 1 1 1

a) In which of the following cases will the robot start walking? i. The robot is far from the wall. ii. The battery status is good. i. The room lights are on. iv. Both i and ii. v. Li, and ilil. vi. ii and ii, but not i. . vii. į and ilii, but not i. b) Explain what happens to the robot if the light is turned off. c) If you remove the light sensor and the AND gate attached to it from the circuit from the circuit, which of the following are true and which are false? i. The robot will continue to walk with a low battery ii. The robot will stop walking if it is close to the wall iii. One of the remaining inputs (proximity sensor and battery status) is irrelevant to whether the robot walks or not. iv. There is only 1 configuration of inputs possible for the robot to walk
