Define a robot in your own words., programmable machine that performs tasks automatically based on instructions/sensor inputs., List two input devices of a robot and two output devices of a robot., Inputs (sensors: ultrasonic, color, light, sound, buttons/joystick), Outputs (motors, servos, LEDs, speaker)., Which sensor is used to measure distance for obstacle avoidance in mBot2?, Ultrasonic sensor, Write three characteristics of a robot, programmable, automation, sensing, autonomy, mechanical manipulation, versatility, CyberPi includes several built-in components. Write any four, LCD screen, microphone, speaker, joystick, buttons A & B, RGB LEDs, tilt/shake/motion/rotation sensors, sound sensor, light sensor, In mBlock, what is an extension, and why do we add the mBot2 shield extension?, Extension adds device blocks; mBot2 shield adds motors/sensors blocks., You want the robot to move in a rectangle automatically. Write the plan steps (no code yet) for one full rectangle (4 sides + turns)., Forward → turn 90° → forward → turn 90° → forward → turn 90° → forward → turn 90°., For controlling the robot in a maze using the joystick, describe the logic using forever and if statements:, forward→move forward (e.g., 40cm); left→turn 90° left; right→turn 90° right., In mBot2 chassis motors, which motor is:, EM1 left, EM2 right., Explain the difference between controlling wheels automatically vs manually, Automatic uses combined movement blocks; manual uses encoder motor blocks per motor., Variables in robotics missions:, name + content/value; set assigns a value., What is the difference between set [variable] to and change [variable] by?, set overwrites value; change increases/decreases relative to current value., Obstacle avoidance mission: The robot repeats moving forward and checks distance using the ultrasonic sensor., stop when distance < threshold (10cm); repeat until keeps checking continuously.
