This company is building a massive pack of robot dogs for purchase starting in 2019

They can unload the dishwasher, deliver packages to your home and open doors. Their thin, metallic legs are able to traverse a steep flight of stairs -- or crawl straight into your worst nightmares. Now Boston Dynamics' awkward, four-legged, doglike robot, SpotMini, is evolving from a YouTube sensation to a purchasable pet of sorts, according to the company's founder, Marc Raibert. Raibert told an audience last month at the CeBIT computer expo in Hanover, Germany, that his company is already testing SpotMini with potential customers from four separate industries: security, delivery, construction and home assistance. His presentation at the expo was reported by Inverse.
