[SOLVED] Stuck at Exercise 5.5 - mBlock Blockly iPad app

#1

Hi there, we’re stuck on exercise 5-5 in mBlock Blocky (iPad app) for the mBot. The English instructions say: “Tell the mBot to move forward, and turn left for 1 second until there is an obstacle ahead.” Based on how this was written we tried:

  1. Move forward
  2. Turn left
  3. Wait until - Obstacle ahead

That did not work. So we also tried:

  1. Move forward
  2. Wait until - Obstacle ahead
  3. Turn left

That also did not work. I tried re-installing the online firmware, and that didn’t seem to help.

What are we doing wrong here?

Thanks.

I do not know of there is a fix or not. Can you contact Makeblock Support and get back to me?

hi @dbbate

Try dragging the ‘wait until’ block under the ‘when clicked’ block then drag the ‘obstacle ahead’ block under the ‘keep moving forward’ block, and add the ‘turn left for 1 second at the speed of 150’ under it - as shown below:

Thanks folks! I had originally tried the suggestion from @CommandeR and it didn’t work. But then I reinstalled both the online firmware and the factory firmware, and I was able to get that code to work. Seems like it was an combination of both poor instructions and a firmware problem. But we’re good to go now. Thanks!
