Bobb3e beeps his alarm whenever reversing.

Bottom-Right/Blue-Down: turn right backward.

Bottom-Left/Red-Down: turn left backward.

Top-Right/Blue-Up and Bottom-Left/Red-Down together: turn right on the spot.

Top-Left/Red-Up and Bottom-Right/Blue-Down together: turn left on the spot.

2 Bottom/Down Buttons together: drive backward.

2 Top/Up Buttons together: drive forward.

Drive Bobb3e around according to instructions from the IR Beacon:.

Make Bobb3e lower the forks by pressing the IR Remote Control’s 2 Left Buttons together make him raise the forks by pressing the 2 Right Buttons together This program requires LEGO® EV3 MicroPython v2.0 downloadable at.

This remote controlled Bobcat® can be steered to move and lift objects with the control buttons on the IR Beacon. Building instructions Improve project Image credit: LEGO
