Two specific “breeds” of robodogs, Spot from Boston Dynamics and the vision series from Ghost Robotics, are now commercially available. Both cost around $75,000, weigh about 30 kg and are about the size of medium-sized dogs. Both companies make similar claims about mobility and features, and both units can be remotely monitored and controlled.
Robotic autonomous vehicles, or semi-autonomous vehicles, are not new but these are more often aerial drones, or wheeled ground vehicles. But these robots have legs. They have technology (of different types) that allows them to negotiate any terrain a four-legged dog could — and to recover their footing if they fall down.
