As reported by [arstechnica]:
The time has finally come, Boston Dynamics robotic quadraped Spot is now on sale on [their site] for a cool 74,500$ with a 1,000$ deposit. It weighs 71 pounds and comes with two 605Wh batteries that gives it 90 minutes of operating time a piece, 2.4GHz multi-spectrum wifi, wired gigabit ethernet, a top speed of 1.6m/s, or 3.58mph, and can handle payloads of up to 30.9 pounds. The controller is a 7-inch android tablet thats like a mix between a Nintendo Switch and an Xbox controller.
While this is likely out of many's price range, you can still flip through the [manual], checkout their [basics videos], or check out [Adam Savages] reviews of them. Note that the Spot isn't a toy or "three laws safe", and they explicitly don't want people using them at home, for example you could potentially lose a few fingers if they get near the motors while active. The Spot also comes with numerous mounted addon modules, such as the Spot Arm, Spot Camera, Spot GXP, Spot Core, a 360 degree camera, or Lidar with an integrated compute module.
