You can apparently buy a Laikago for $25K USD (although I could not find pricing on their website just an intention to buy http://www.unitree.cc). It looks somewhat similar to Boston Dynamics Spot I think it would make a good platform to add Robot Arms, LIDAR, Cameras etc, just plugin your EZ-B :-). If you visit their website they have a developers edition (Looks like it is same as production but no battery - connect to mains I guess) and they also sell individual servo's and controllers (out of stock). The battery is a 100A LiPo by the look of it and can charge between 5A to 10A. Shipping this will be fun.
