I have seen this G-Dog some time ago. Finally, it is out of prototype and ready for sales. Although not as cute as a real dog, it needs little maintenance. Watch it plays.
Here is the video. BTW, it will set you back by USD815 to USD930 depending on configuration and accessories. The G-dog is quite customizable. You can add gears to make it more “flexible”. It is just 19cm tall and 570g. Battery life is a little short at 45 minutes before it goes to rest.
