Taking elevators
Navigation continues through vertical transitions common in stations, malls, and hospitals.
Technology
Intelligent navigation, user-centered interface.
Our patented topo-navigation algorithm and user-centered interactive system turn an off-the-shelf robot dog into an intelligent, self-propelled companion.
How it works
A trustworthy guide, but also a partner.
The robot not only has a map of the environment, but stays constantly aware of moving obstacles — pedestrians, vehicles, and other traffic — and smoothly guides the user around them while following the optimal path. It is as easy as holding the arm of a friend.
The person remains in the loop. They can add or change destinations, control walking speed, and take the lead in tight spaces such as opening a door or entering an elevator. The user can also steer the robot; it coordinates with those instructions instead of taking over.
Capabilities
Built for daily environments.
Opening doors
The system supports environmental interactions, not only point-to-point walking.
User-centered interaction
Handle-based control keeps the interface physical, immediate, and low in cognitive load.
Obstacle avoidance
Environmental perception helps users move around people and objects without stopping at every turn.
Location awareness
Route cues help users know where they are, which is essential in large, repetitive interiors.
Safe, low-maintenance design
A practical alternative to long waitlists: easier to maintain and more available at scale.
Research
Peer-reviewed, field-tested.
The work behind RoamAssist is published at CHI and HRI, including a CHI 2024 Honorable Mention for guiding visually impaired people in diverse environments.
