Boston Dynamics: Introducing Handle

Handle is a research robot that stands 6.5 ft tall, travels at 9 mph and jumps 4​ ​feet vertically! ​It uses electric power to operate both electric and hydraulic actuators, with a range of about 15 miles on one battery charge. ​​​Handle uses many of the same dynamics, balance and mobile manipulation principles​ found in the quadruped and biped robots we build, but with only about 10 actuated joints, it is significantly less complex. Wheels are efficient on flat surfaces while legs can go almost anywhere: by combining wheels and legs Handle can have the best of both worlds.

Imagine, this used to be only seen in a movie using special effects. But this thing is real, and not tethered! 

The video gave me a sense of awe, and a bit of 'yikes'. Welcome to the future. A matter of time until one of these gets armed with a weapon.
