Just assembled GoPiGo2, updated all FW and launched basic_test_all.py. Sent cmd: w, right motor was rotating but left was not. It seems that there is no signal on left terminal. Also tried cmd: i - and it did not work as well. Swapped motors and one that was connected to the left terminal was not rotating. So motors themselves are fine.
Hey Stan,
If you’re brave enough with the hardware, you might check that the motor connections are soldered correctly. However, if you’d prefer not, I think this might be damaged hardware. Where did you get the GoPiGo from?
Thank you for reply. I bought it online from www.dexterindustries.com. I am quite confident with the hardware and pretty sure that there is nothing coming out from the left motor header - checked with a scope. I am just wondering if is anything I have missed and have not updated properly?
Ok. It looks like you already tried to update the firmware. I think the board is defective then. It must not be sending commands between the microcontroller and the motor chip. Can you reach out to us here: http://www.dexterindustries.com/contact/ and include this forum thread, and your order number? We can arrange a replacement.
I see you submitted a ticket on Saturday. Typically we let our folks take their weekends off, I would expect you to hear from someone on Monday about a replacement.
