Boston Dynamics gives robot 'Spot' an arm

The four-legged Spot went on sale last June starting at $74,500 and can perform autonomous remote inspections and data collection. The company says there are over 400 Spots out in the world, including on a factory-floor at Ford and helping with oil rig inspection for BP.

On Tuesday (Feb. 2) the company unveiled an expanded product line, including a new version of Spot that comes with self-charging capabilities and a dock, meaning it can work around the clock, returning to its docking station for recharging before continuing its duties.

The new arm-like protrusion with a gripper at the end has been in development for some time and was top of the wish-list for many clients, said Michael Perry, VP of Business Development.

Spot can now manually or semi-autonomously grasp, lift, carry, place, and drag objects. In an industrial setting, Boston Dynamics said it can "open and close valves, pull levers and turn handles and knobs in coordination with its body to open standard push and pull doors."
