When I turn off the gyro everything seems to work better. For some reason if I first start off with a forward command I get a tip over but if I back up first then I can go forward without an issue. Strange. Maybe recalibrate the gyro?

Reuploaded writeInstinct and OpenCat per your instruction. Video shows what happens when I give a "forward" commend. Thanks George S.

Entered "Y" for instincts and then could enter calibration. Wonderful robot, works great. Thank you for a wonderful design. George S.

Entering "Y" to the prompt for Instincts instead of "n" allowed me to continue on to calibrate.. What an impressive design and execution in its manufacture. Your instructions and videos are really the best of I have seen in robotic kits. You should be proud and thank you for an enjoyable project and a fun robot cat to play with .

That worked. Thank you.
