El-E: An Assistive Robot

First, El-E is equipped with a laser pointer interface that detects
when a user illuminates a location with an off-the-shelf green laser
pointer and estimates its 3D position. This enables a user to
unambiguously communicate a 3D location to the robot using a
point-and-click style of interaction, which provides a direct way to
tell the robot which object to manipulate or where to go.
