First, the script begins by importing the cyberbot and feedback360 modules as expected. Next, the script starts the feedback360.drive system with drive.connect(). Then, the script enters an endless while True: loop that monitors the micro:bit module’s B button to see if it was pressed.
# cyber_bot_gripper_forward_object_distance_with_fb360 from cyberbot import * from feedback360 import * drive.connect() display.show(Image.ARROW_E) while True: if button_b.was_pressed():
If the B button was pressed, the cyber:bot starts by lowering and opening the Gripper. Next, it rolls forward for half of a wheel turn, then stops. Then, the script uses bot(15).servo_angle(30) to close the Gripper. That is followed by sleep(1500) to give the Gripper time to close and lift, and partially to make a slight pause between picking up the object and starting to move.
display.clear() bot(15).servo_angle(150) # Lower & open gripper sleep(1500) drive.goto(32, 32) # Forward 0.5 wheel turn bot(15).servo_angle(30) # Close gripper & lift sleep(1500)
After lifting the object, this part of the script makes the cyber:bot roll forward 1.5 wheel turns. Then, it lowers and opens the Gripper, letting go of the object.
drive.goto(96, 96) # Forward 1.5 wheel turns bot(15).servo_angle(150) # Lower & open gripper sleep(1500)
Finally, it backs up half a wheel turn so that the object is no longer between the Gripper paddles.
drive.goto(-32, -32) # Backward 0.5 wheel turns display.show(Image.ARROW_E)
