| 20090045766 | OBSTACLE FOLLOWING SENSOR SCHEME FOR A MOBILE ROBOT - A robot obstacle detection system including a robot housing which navigates with respect to a surface and a sensor subsystem aimed at the surface for detecting the surface. The sensor subsystem includes an emitter which emits a signal having a field of emission and a photon detector having a field of view which intersects the field of emission at a region. The subsystem detects the presence of an object proximate the mobile robot and determines a value of a signal corresponding to the object. It compares the value to a predetermined value, moves the mobile robot in response to the comparison, and updates the predetermined value upon the occurrence of ah event. | 02-19-2009 |
| 20090177323 | COMPANION ROBOT FOR PERSONAL INTERACTION - A mobile robot guest for interacting with a human resident performs a room-traversing search procedure prior to interacting with the resident, and may verbally query whether the resident being sought is present. Upon finding the resident, the mobile robot may facilitate a teleconferencing session with a remote third party, or interact with the resident in a number of ways. For example, the robot may carry on a dialogue with the resident, reinforce compliance with medication or other schedules, etc. In addition, the robot incorporates safety features for preventing collisions with the resident; and the robot may audibly announce and/or visibly indicate its presence in order to avoid becoming a dangerous obstacle. Furthermore, the mobile robot behaves in accordance with an integral privacy policy, such that any sensor recording or transmission must be approved by the resident. | 07-09-2009 |

| 20100076600 | MOBILE ROBOT FOR TELECOMMUNICATION - A mobile robot provides telecommunication service between a remote user at a remote terminal and a local user in proximity to the mobile robot. The remote user can connect to the mobile robot via the Internet using a peer-to-peer VoIP protocol, and control the mobile robot to navigate about the mobile robot's environment. The mobile robot includes a microphone, a video camera and a speaker for providing telecommunication functionality between the remote user and the local user. Also, a hand-held RC unit permits the local user to navigate the mobile robot locally or to engage privacy mode for the mobile robot. When NAT or a firewall obstructs connection from the remote terminal to the mobile robot, an Internet server facilitates connection using methods such as STUN, TURN, or relaying. | 03-25-2010 |
