This dog-like robot can climb stairs, jump, and even play fetch. But it’s not a replacement for your household pet. The robot, named Spot, was built to work. Engineers at the company Boston Dynamics designed Spot to perform jobs that can be difficult or dangerous for people. The 0.8 meter (2.6 foot)-tall machine has a robotic arm it can use to open doors, and built-in devices to detect objects. “Spot can use its sensors to measure progress on construction sites and do tests in factories to make sure everything is safe,” says Boston Dynamics founder Marc Raibert.
