Because if it gets to the free-throw line, it sinks the shot – every. single. time. This robot is the project of a group of Toyota engineers using their spare time, to build a robot inspired by the manga Slam Dunk, which is about a Japanese high school basketball team.
The engineers brought their robot out to face off against humans, (pro players, though pro players from a B–league in Japan, not NBA) but the robot nailed it every time. Still, it’s a free–throw competition – humans still have a gigantic lead on other aspects of basketball, like most of them, in fact.
