Dear Rongzhong Li,
I was one of the backers on Kickstarter for the Robot Dog project and received mine this week. So, I would like congrats you for the quality of the kit and all your efforts for delivering orders. It was certainly a long journey that is not ended for you and your team, but you already have succeeded.
No issue during assembly except for the servo head wire that looks definitively too short whatever the way when screwing to the board, but it was easily replaced by the servo in spare with longer wire. However, I have some questions regarding the software and if you can advise me it would be great before have a look at the code.
I ‘m confronted to few problems. The most recurrent is something that looks to me a bug with the OpenCat code (uploaded from GitHub recently) when gait walk is requested by IR remote. There is no way for stop the robot by press on Balance or whatever button of the remote. This does not happen with other gaits like Crawl or Run that are working perfectly and can be stopped. Moreover, the walk is the sole gait that doesn’t looks smooth, starting with a twitch and the robot is frequently falling despite I have repeated several times the servo calibration. Another point that I observed is a short contact of the front knees with the underside of the frame at each steps.
So could you advise me for fix this problem and improve my user experience. Many thanks.
