A robotic system includes a plurality of robotic elements, each having at least one processing component, at least one memory component, and an I/O interface; and a virtual backplane coupling the plurality of robotic elements.

Robotic system with distributed integrated modular avionics across system segments

A communication network comprises a communication bus and at least two line cards. Each of the line cards are coupled to the communication bus The line cards comprise a processor and a configuration memory coupled to the processor. The communication occurring on the communication bus is predetermined, but can be reconfigured during real time operation by events or by the addition or subtraction of line cards. The configuration memory comprising an array of configuration tables, each configuration table storing a listing of processes to run and data to be transmitted or received by the process. A current configuration table is selected from the array of configuration tables upon the occurrence of a predefined event.

Reconfigurable virtual backplane architecture

Method and apparatus are provided for preventing faulty commercial-off-the-shelf (COTS) peripherals or I/Os from disabling the bus to which they are connected. The apparatus has isolators coupled to the bus and the I/Os. A controller is coupled between the interfaces, a processor and memory, operating such that an I/O cannot transfer data to the bus without permission from the bus. Isolation memory keeps I/O and bus messages separate. I/O messages are checked before being sent to the bus. The method comprises: determining if there is a message for the peripheral, temporarily storing the message, determining if the message is for output or input, and if for output, sending it to the peripheral, and if for input, requesting and receiving it from the peripheral, temporarily storing and checking it, and transferring it to the bus only if valid. This prevents a failed I/O or peripheral from disabling the bus.

Protective bus interface and method

A digital motor controller circuit including a an energy storage device, a bus protection circuit, an input signal selector, a combiner, a calibration device for altering parameters for different applications, a compensator, a motor driver circuit, and feedback circuitry for controlling a motor with a minimum of cost and space requirements.

Single board motor controller

A motor controller circuit including an energy storage device, a bus protection circuit, an input signal selector, a combiner, a compensator, a modulator, a motor driver circuit, a commutator, a feedback circuitry and a plurality of filters, resistors, inductances, capacitances and optical isolators all contained on a single circuit board for use in controlling a motor with a minimum of cost and space requirements.

Low cost high performance single board motor controller

A task scheduler system including an array of priority queues for use in a real time multitasking operating system including equation lists, configuration lists, a function library, input and output drivers, user-created task definition lists of major and minor tasks and interrupt handlers. The system includes task scheduling apparatus which, upon the completion of each library function, interrogates the priority queues and finds the highest priority task segment whose requested resource is available and executed, and which executes task segments in the same priority queue in round-robin fashion. The system further includes task creation apparatus and apparatus for maintaining the status of all major tasks in a system in the states of unlocked and done, unlocked and active, unlocked and waiting, locked and active, or locked and waiting. The status maintaining apparatus also includes apparatus for locking tasks into a mode of operation such that the task scheduler will only allow the locked task to execute and the normal state of priority execution is overridden, and waiting apparatus for suspending operation on a task that requires completion of a library function.
