Timix is a distributed real-time kernel that is being developed to support multisensor robot systems. The overall structure of the kernel is described, including a hierarchy of interprocess communication primitives and a generic way to interact with external devices. A simple multisensor robot that is being implemented using Timix is also presented. Three salient aspects of Timix are as follows. First, it is possible to estimate the amount of time that a real-time process takes to execute since the execution times of system calls are bounded. Second, an hierarchy of communication methods, which differ in synchronization, time and space overheads, and bandwidth requirements, are provided to allow the programmer to choose the one most applicable to a particular application, depending on the real-time requirements. Finally, new devices, which ar directly controlled by application processes, can be integrated into the system without changing the kernel.< >

sensor data fusion takes many forms and has diverse purposes. sensor data fusion can improve a complex robot's picture of the world and increase its confidence in the truth of that picture. A computing architecture which supports many different schemes for fusion sensor data is necessary to support the activities of complex robots. One such architecture is the distributed blackboard mechanism implemented onboard the USMC ground surveillance robot. The distributed blackboard has proved to be a very useful and flexible mechanism for accomplishing effective sensor data fusion.
A modular and expandable distributed microcomputer hardware and software system is described that matches the natural needs of real-time mechanization of manipulator control in space teleoperation. Those needs include...

A modular and expandable distributed microcomputer hardware and software system is described that matches the natural needs of real-time mechanization of manipulator control in space teleoperation. Those needs include: (a) distribution of real-time control computing power between control station and remote robot arms equipped with smart end effectors;and (b) the use of interchangeable control techniques like (i) generalized force-reflecting hand control, (ii) sensor-referenced automatic control, and (iii) supervisory control with interface to high-level task planning control. The distributed microcomputer control system is also handling computer graphics displays and the control of TV cameras. The authors describe the major components of the modular control software system including interprocessor communication and control mode selection. A simulation example is quoted to verify control hardware/software performance and to aid human operator control performance studies.

The natural needs include: (a) distribution of real-time control computing power between control station and remote robot arms equipped with smart end effectors and (b) the use of interchangeable control techniques like (i) generalized force-reflecting hand control, (ii) sensor-referenced automatic control and (iil) supervisory control with interface to high level task planning control.
