inside the ball a tripod with weels (could you call it a trike?) makes the ball go round. similar to available lawn mowing robots, it is fenced by a wire, and it is able to find the recharge station. Status: shelved for now Problems: -Quite expensive for a non-sense gadget. On the other hand, I could immediately name 50 products with a worse reasonable vs. price ratio.... - Ball and mechanics need to be stable enough against kicking feet. Or so heavy, that it definitely is no fun to kick! Applications scenarios: - private gardens - imagine elderly people where kids have left, they want something move in their garden? - hotel garden or park - imagine soccer world or EU championship! - company garden or park - to cheer up employees a bit. Wanted: Opinions! Like it? See a market? Interested in spending expertise, time, money? drop a msg! best regards from Munich in Germany, home of world's best Soccer club Bayern Muenchen (as Bayern sees itself)
