MIT's New Robot Understands Pedestrian Etiquette

Pedestrian etiquette – things like not walking into oncoming traffic or keeping to the right of the sidewalk – comes naturally to humans. However, while robots have been programmed to accomplish many things, teaching them to navigate among crowds has proved a challenge because it is hard to accurately predict each person’s path. Now, a team of MIT engineers, led by Steven Chen, have overcome the hurdle with a knee-high autonomous machine that can seamlessly weave itself through people, paving the way for errand-running and pizza delivering robots.
