Tesla has a history of making big promises. But its newest one is just average size, about 5-foot-8 and 125 pounds, according to CEO and self-professed “Technoking” Elon Musk. Tesla says it plans to build a humanoid robot to perform basic tasks, such as wrenching on cars or making grocery runs. It’s part of the company’s broader ambitions in automation, which include building its own computer chip, dubbed the D1, to power the networks for vehicles it hopes to one day make self-driving. Tesla previewed the concept at a presentation at its Fremont, Calif., factory on Thursday, dubbing it the “Tesla Bot” and “Optimus,” and said it would show a prototype next year. As part of the presentation, a human dressed as the machine made robotic gestures and then danced onstage, perhaps demonstrating the range of motion Tesla hopes the bot could one day achieve.

Phoenix police are asking for the public's help identifying four armed men who attempted to rob a Phoenix homeowner. Officials say on August 12, officers were called to a home near 36th Drive and Pinnacle Peak Road to investigate a robbery call. Police say the homeowner was alerted by his security cameras to a motion outside. Video shows four men, some of who appear to be armed, kick in the front door. The victim got his handgun and fired multiple rounds towards the front door, and the suspects could be seen on the footage fleeing the area. The suspects' vehicle is described as a silver or gray four-door sedan.

If anyone has any information, they are asked to call the Phoenix Police Department or Silent Witness at 480-WITNESS (480-TESTIGO for Spanish).
