A human-robot interface for a mobile robot was extended to include a discrete geodesic dome called a Sensory EgoSphere (SES). The SES is a two-dimensional data structure, centered on the robot's coordinate frame. The SES provides the robot's perspective of a remote environment via images, sonar, and laser range finder representations. It was proposed that(More)
This paper describes the supervisory control of mobile robots using a biologically inspired short-term memory structure called a Sensory EgoSphere. The EgoSphere is implemented as a virtual geodesic dome upon which sensory data from the surroundings of the robot are written. The EgoSphere is managed by a distinct agent in a distributed agent-based robot(More)
This paper presents how a Sensory EgoSphere (SES), a robot-centric geodesic dome that represents the short term memory of a mobile robot, could enhance a human-robot interface. It is proposed that the addition of this visual representation of the sensor data on a mobile robot enhances the effectiveness of a human-robot interface. The SES migrates(More)
A revised version of the Intelligent Machine Architecture (IMA) software architecture and development environment has been implemented. The IMA 2.5 software architecture provides support for distributed concurrent programming using integrative robotics approaches. These approaches combine agent-based, behavior-based, and reactive algorithms to provide(More)
