There goes another job. The robots are coming to replace us. When they're not busy building cars inside of old Detroit factories and measuring the level of radiation inside of the Fukushima Dai-ichi nuclear power plant, robots are throwing out the first pitch at baseball games.

On Wednesday, a robot built by a team of engineers at the University of Pennsylvania opened the Phillies season. The robot "took a month and a half to develop, and was slowly built upon from its humble beginnings as a Segway," according to the Associated Press. "Engineers Jordan Brindza and Jamie Gewirtz slowly built it up, adding a robotic arm with a pneumatic cylinder, giving the pitch a speed of likely somewhere between 30 and 40 miles an hour," the Huffington Post added.

Despite a test run on Monday, though, 30 or 40 miles an hour wasn't enough to get the pitch over the plate. So, pitchers: You can rest easy. For now at least.
