Abstract
An unmanned vehicle operated autonomously or by remotely piloting incorporates an onboard camera which is affixed with clear tape coated with a chemical colorimetric sensor dye sensitive to chemical warfare agents. Chemical warfare agents are detected by visual review or autonomous measurement of sensor color changes while the unmanned vehicle travels through a region suspected of having chemical warfare agents present. In various implementations, the sensor output color changes may be visually monitored by a vehicle operator viewing the camera image from a remote location. In various embodiments, the detection of chemical warfare agents may be confirmed by processing the coated tape with a calibrated opto-electronic reader.
