Like some toy from the 1980's this small robot using a piston-actuated "leg" can bounce itself over fences.
Doesn't seem to me to be a very practical machine, it has to roll on either side meaning it has no 'top'. Also any equipment on it will be easily
damaged. Much easier to make a small hole in the fence for it to pass through. Put it on the "great idea needing a purpose" list.
I would like to see it drive between the legs of a Taliban instead and then jump :)
