After a few omissions on my part I got a good calibration and OpenCat install. After a few IR commands Bittle freezes or goes into wild servo movement and again freezes. Rebooting Bittle by turning him off and on works again for only a few moves. I reinstalled Arduino IDE and downloaded a clean version of OpenCat and required libraries, Again got a clean calibration and OpenCat install. Bittle still locks up (crashes) after one or two commands. I also tried my IR remote from Nibble with the same result. A design observation. The IR receiver is somewhat hidden by its location. Vey impressed with the molded plastic parts and overall design and packaging. Thanks again George S

I'm having problems compiling OpenCat for Uno. If I understand the error message below the sketch is too big for available memory. I installed IRremote 2.6.1 and commented out all remotes except RC5, RC6 and NEC. Thank you for your help.

Using Arduino 1.8.13. Selected NyBoard V0_1 board and correct COM and get the following summary alert... An error occurred while uploading the sketch avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x3a (repeated nine more times) Any suggestions? Also thanks for the effort to get Bittle built and delivered

WriteInstinct locks up after MPU calibration. No response after to "c" command. Have latest Arduino IDE, NyBoard support, updated libraries, edited Instinct.h to NyBoard_V0-2 Serial Monitor 57,600 baud, No Line Ending All servos connected, battery switched on Install WriteInstinct and open serial monitor, Reset Joint calibration (Y) Update Instincts (n) I get single lines 1-42 and Finished! Calibrate MPU (Y) Finished! Offsets saved automatically type "c" beep and no further response in serial monitor If I close and reopen serial monitor entire process starts over again with same results. Any suggestions and thanks. George S.
