Telepresence robots have emerged as a new means of interaction in remote
environments. However, the use of such robots is still limited due to safety
and usability issues when operating in human-like environments. This work addresses
these issues by enhancing the robot navigation through a collaborative
control method that assists the user to negotiate obstacles. The method has been
implemented in a commercial telepresence robot and a user study has been conducted
in order to test the suitability of our approach.
