It is amazing, but..
I saw video from same company, they were field testing a military robot burro. Looks like a mechanical elephant, carries gear and follows soldiers on foot.
Cool as heck, but from the terrain they were on, you'd think a light tank could cover the same ground. Then compare the mechanical complexity of a robotic elephant vs. a tank.
How will the robot hold up to dirt, dust, and water, let alone taking a single round of enemy fire? And.. will the guys on the ground know how to fix a malfunctioning robot?
Definite cool factor, but I question the practicality...
