This is a question that is on my mind for some time now and when I discovered this forum, I thought that it might be the best place to get some answers.
I have a dog with an amputated right hind leg - the amputation has been done in a way that there is no bone left in his right hip, unfortunately, meaning no conventional prosthesis can be used. But the muscle remnant of the leg is clearly moving during various activities (peeing, scratching, digging, etc.) - so it is giving out signals to the missing leg. Would there be a way to develop a robotic leg prosthesis that would respond to these muscle signals? I know there are many robotic prosthesis projects for humans, but I have seen none so far for animals - is it because it would pose too many challenges, it would be too costly or maybe it is just not possible? What do you think?
