Promobot, the company that designed the robot, announced the escapade in a blog post the next day.
The strange escape has drawn skepticism from some who think it was a promotional stunt, but regardless of whether the incident was planned, the designers seem to be capitalizing on all the attention. The company's blog includes photographs of the robot from multiple angles as it obstructs traffic, and the robot's escape came a week after Promobot announced plans to present the newest model in the company's series, Promobot V3, in the fall.
