Thank you for your answer and participation.
Thank you for your answer and participation.Oh, Holy Crap! This is just about the worst idea ever conceived in the area of dog ownership. No. Just.... No.
Thank you for your feedback and participation in the survey!This is possibly the worst idea I've ever heard of. If you can't walk your dog then why do you have a dog... and why does the dog have you? Both you and your dog need those moment for bonding. I actually answered the survey but it's not going to be the encouragement you hoped for. There is no technology currently that even comes close to being reliable enough that I would let my dog out of the house leashed to one. No way. No way!
If you want to develop a useful robot (dog or non dog related) then try focusing on one that can do light house keeping and/or surveillance tasks (possibly related to the dog) when you are not home. I could see a role for a robot in the house that kept an eye on the dog but beyond that my Roomba is more useful to my dog than a walking robot would be. Moreover, a dog will know it is not human and while I'm pretty sure you could train a dog to tolerate the presence of such a machine, they're not going to warm up to it.
