I think that for some of Dr Guy's moves he must have a slightly different home position.
I will try to make the home position as good as I can get it and then adjust the moves slightly for my robot, not the other way round. It might mean less compatability with other users but I have spent 2 weeks trying to get the trim right using the correct process. Time to start making my own moves
Getting the home position setup correctly takes some practice, and is hard to do when you're working by yourself, especially since you are usually very close to the robot so the perspective tends to be distorted a little. The same thing happens when you try to hang a picture on the wall by yourself, then step back and see that it's a little tilted one way or the other. Only in this case we're working in three dimensions.
The other problem is that home position adjustments are made with the robot fully extended, but affect it's performance throughout the servo ranges.
If you understand how to create links in H2H3 (they are extremely useful and worth studying), then setup one to do a 'squat'. Here's a short version-
1- Create a link, name it 'Squat' - or anything you like and can remember.
2- Set the leg pitch channels -
CH12: MOV(10)
CH13: MOV(20)
CH14: MOV(10)
CH18: MOV(10)
CH19: MOV(20)
CH20: MOV(10)
3- Save the link.
When you think you have the home position set correctly, then use the link along with the red/blue arrows to make the robot squat down and back up evenly.
If the body stays vertical along both the pitch and roll axis as it goes up and down, then the home position is probably okay. If it tilts back/forth/sideways or any combination, then the home position is off, and you can usually tell by the tilt where it needs to be adjusted.
The poor quality of the video's will continue. I have a very addictive personality, if I try to master Adobe Premier, I will be sucked away from robots into the mysterious land of video editing very quickly
The video quality is basically okay. The main improvements I would suggest would be more light, and plenty of it. A tripod would help also, but isn't absolutely necessary.
Good luck!
