New Robot Does Nothing

RE: New Robot Does Nothing
Two IMUs failing is the most reasonable explanation here (?). But that is quite odd.
Are the IMUs headers (back of the PCB) touching the WIFI moduleĀ“s metal case? Did you use the double sided tape to fix it to the Brain shield?

Ask jjrobots for a replacement, they are a bunch of good guys. I am sure they will send you another pair of IMUs >Big Grin

RE: New Robot Does Nothing
Thank you for your prompt reaction guys.

1) Are you using alkaline batteries? Very low voltage batteries will not have enough power to move the wheels
- Fresh alkaline batteries - there is 9.6V at the input.

2) If you lift the B-robot, does it spin the wheels?
- No. I tried to turn it to different angles with no reaction.

3) Can you swap the IMUs of the B-robots and see if they behave the same?
- I will try.

4) Does the led on top of the IMU lights after switching the Brobot ON?
Yes both Arduino and IMU LEDs are on.

I was in fact worried about shorting some naked wires with the IMU and heatsinks so I have placed them quite carefully.

Update: When I disconnect the IMU the robot starts turning wheels and moving the hand. So it definitely seems the IMU is not working correctly. I will get a replacement and let you know.

I do appreciate your customer care Shy However I couldn't wait and got one spare IMU locally. Now everything works perfectly.
