I used Scratch before a bit, but am new to the mBot. I want to control the robot with the keys on my computer keyboard. It works already pretty good, if an arrow is pressed, it will go in said direction, if I release the button it will stop.
[when up arrow key pressed] - run forward at speed 100
[when up arrow key released] - run forward at speed 0
Now I want to include the Ultrasonic Sensor, so I tried to implement an “if - else”.
It works, but not properly: if the robot is too close to an obstacle when I press the up arrow it will rotate to the right and then go forward. But if it is already running and an obstacle comes closer, it just keeps on running…
I am not sure if it is my fault or if the 2.4G connection is just too slow?
Attached is my code:
