Watch: Biomimetic robo bird-plane leaps to launch

While autonomous flying robots have some intriguing potential applications, their usefulness is limited if they can't move across uneven terrain once they land. A new bio-inspired bot can do so, however, by mimicking the gait of the raven.

Crop-spraying robot is designed to reduce emissions and use less herbicide

The spraying of orchards and vineyards certainly isn't an eco-friendly process, with tractors spewing exhaust as they douse crops in herbicides and pesticides. That's one of the main reasons the electric, autonomous Prospr robot was created.

Watch: Flat out fast two-legged robot designed like a Velociraptor

The fastest any human has ever run on record was Usain Bolt. He was clocked at a ridiculously quick 27.79 mph (44.72 km/h) when he ran a 9.58-second 100-meter dash. Two-legged robots can run even faster, and it looks really weird.
