How Does Dax Know Where to Go?

Will Dax Bump into Things or Run Over People?
Dax has collision detection, just like some cars do. He is able to detect and avoid hazards mostly on his own, but he can also send an alert to his operator to help him navigate an especially congested or tricky area. Dax also has an emergency stop that can be activated remotely by the operator or physically by a bystander.

Probably. But Dax is heavy and hard to steal. He also has GPS, and a brain, and cameras. So there’s not much point because we can find him quickly.

Why Doesn’t Dax Use ROS?
Dax runs on a ROS-like system called DaxOS. The difference is that DaxOS is newer than ROS; it favors Node over Python or C++ and it adds certain features like multi-chip voting and a centralized datastore. DaxOS also allows us to bake safety-related code into the master and not rely on a node, which could otherwise die while the master is left running.
