The ORI-SR safety radio system provides a remote controlled “Safety
Interlock” for unmanned vehicles. It is derived from the DGCSR radios provided to the Defense Advanced Research Project Agency (DARPA) for all DARPA Grand Challenge and Urban Challenge events.
The ORI-SR allows a safety operator
to remotely 'PAUSE or RUN' and 'ENABLE or DISABLE' one or more vehicles
at any time. The ORI-SR consists of two main components:
the Safety Receiver (on right, above); and the Safety Transmitter (on left, above). The Receiver is intended to be integrated
with the unmanned vehicles engine and control electronics. The Transmitter is intended to be operated
by a human safety monitor/supervisor from a remote position. By
flipping toggle switches on the safety radio transmitter, the relays and opto-isolated
digital outputs are asserted on the Receiver, controlling the RUn or Pause function, and Enable or Disable function. LED indicators
on the Transmitter reflect the acknowledged state of the Receiver.
In addition, if the radio link between the Transmitter and Receiver
is lost for any reason, the PAUSE and DISABLE outputs will automatically
assert after a programmable delay time.
For previous-revision DGCSR owners: An upgrade for a point-to-point
mode option which reduces the reaction time to less than 100 ms
(typical) is available for $250.00 plus shipping.
