Rather than working on the perfect landing I think a good enough landing would be sufficient (crash and get back into ready to jump posture).
That's been done a few times. The first time was a mobile land mine developed at Sandia. It was a ball with a fuel-powered piston for jumping. After each jump, it used an interior weight to get itself positioned and aimed for the next jump. The plan was to drop a bunch of these from aircraft into enemy territory. When one of them detected a good target, like a convoy, all the mines nearby would converge on the target and blow it up.[1]
There's also this small fence-jumping, tracked robot from 2009.[2] Landing is uncontrolled, but it can survive crash landings and run upside down, so that doesn't matter too much.
