Issue with Pixy and Pan/Tilt

Added by HG Mahanty over 3 years ago

Hi

I used pixy to build a pet robot using the instruction from Adafruit.
Everything worked fine for a the first two days , however now the pan and tilt system does not move vertically at all (up or down).
It only moves horizontally.

I will really appreciate any help to fix this issue.

Thank you in advance!

Hi,
I did some more test after reviewing the content on the wiki.
6. Test the servos
Run PixyMon and hit the stop button (upper left corner of PixyMon). In the command window type this, hitting <return> after each line:

rcs_setPos 0 1000
rcs_setPos 0 0
rcs_setPos 1 1000
rcs_setPos 1 0
This should exercise the pan servo first then the tilt servo. The movement should be smooth and rapid. If not, make a note of which servo is acting strange. and send us an email describing your experience ().

The pan is working correctly however the tilt is not working correctly and does not move at all.
Appreciate your help.

Thanks
HG

Hi HG,

Sorry to hear about your troubles. Have you tested the connections? One idea is to swap the pan and tilt servo wires to see if that is the problem. You can also try to localize the problem by swapping the servo motors. That might tell you if it is a servo problem or a problem with Pixy. Any more info you can provide would be helpful. We'll be happy to exchange the Pixy/servo if we can't find the problem.

Thanks for your response Scott.
I have also been working with Bill from Adafruit support and we have localized the problem to be the bad "tilt" servo.
Adafruit will help me out by replacing the servo, I am hoping that will solve the problem and I can get back to enjoying Pixy( which is awesome!!!!)

Thank you for your response!
