mBlock on iPad - obstacle ahead, pick up - not working


by now I’ve found that these two commands doesn’t work - “obstacle ahead”, "mBot is picked up"
Here is the movie for the obstacle avoidance issue:

I did reset as it mentioned here Object detection and line mode not working

Furthermore, “Draw and Run” on Makeblock app is totally failure it doesn’t follow the lines accurate!

Can you help me at least for the mBlock app issues?

Thank you!


My fault, the sensors weren’t plugged into the correct ports.
