New Bot, No run :(
Hi,

I just received my brobot and I'm not able start it correctly.
Everything is setup and assembled.
I start the robot horizontally, wait few second and stand up. During starting the servomortor for the arm run few movement but wheels do not turn at all.
I have tested with a full battery.
I tried to adjust the current output in the A4988 stepper motor drivers rotating the screw indicated on the assembly kit instruction.
I can see the wifi ssid and connect to it.
But I cannot control it by ROVERBOT or TouchOSC app on iOS. Nothing append when I move cursor on both.

On debug mode I get

RE: New Bot, No run :(
Could you please send a video of the starting up procedure? Are you leaving laying flat on an horizontal surface the B-robot so it can calibrate itself and then set it vertical?
The IMU is working so, it should be able to stand on its wheels.
A video helps a lot ;-)
