By Emi The Move Steering programming block is used to make your robot drive forward, backward, turn, or stop, it also adjusts the steering to make your robot go straight, drive in arcs, make tight turns or spin turns. We didn't know that and we wanted to find out. We tested a bit and figured out that the smaller the number in the Steering block, the bigger the circle Eva made. The Move Steering block is a green action block from the EV3 visual programming environment and is used to control both left and right drive motors at the same time, to drive your vehicle in the direction that you select. In a typical EV3 differential drive robot design, the left motor is connected to motor port B and the right hand motor to motor port B on the EV3 programmable brick, as shown above.Good bye!
