MollyA tour guide that walks with you

Molly walks visitors from one point of interest to the next on a Deep Robotics Lite3, tells them about each one, waits when they fall behind and greets people who come up to it. Driven from a handheld and a web dashboard, built on the Dharma stack.

Greeter and followers

The 360° LiDAR sees who walks behind and who comes up: Molly waits for the group and greets newcomers with a gesture.

Handheld and dashboard

A handheld drives and stops the robot; the web dashboard runs tours, shows the map, the camera and the robot's health.
