Polly (robot)

Polly was a robot created at the MIT Artificial Intelligence Laboratory by Ian Horswill for his PhD and published in 1993 as a technical report.

For a few years Polly gave tours of the AI laboratory's seventh floor, using canned speech to point out landmarks such as Anita Flynn's office.

[1] The "Polly algorithm" is a way to navigate in a cluttered space using very low resolution vision to find uncluttered areas to move forward into, assuming that the pixels at the bottom of the frame (the closest to the robot) show an example of an uncluttered area.

Since this could be done 60 times a second, the algorithm only needed to discriminate three categories: telling the robot at each instant to go straight, towards the right or towards the left.

[1] The machine was intended to show that very simple visual machinery can be used to solve real tasks in unmodified environments.
