Raibo2 traversed the challenging 26.2 miles (42.195 km) course in just over four hours, showcasing extraordinary endurance. The marathon presented significant difficulties, including steep hills and variable terrains, yet Raibo2 managed to finish the race on a single battery charge.
While it only ran half as fast as the winning human, that is still really good, moving at over 5mph which by anyone’s standards is faster than walking and is at least jogging.
Perhaps the most amazing aspect of this, aside from reliability and and being able to negotiate the course, is that is managed it on a single battery charge.
Imagine even more advanced technology where it can deliver a payload, just by giving it the address. Presumably being electric means running costs could be low.
