Terrier is a small, lightweight, low cost, tracked vehicle that can investigate and disrupt suspicious objects in a variety of locations. It is remotely-controlled via cable or radio link and the CCTV images from the colour camera are transmitted to the operator's hand-held controller by the same means.
A variety of attachments can be carried on the Terrier's operating arm, including a recoilless disrupter, a grab/manipulator, or an x-ray generator. The robot vehicle is highly manoeuvrable and can climb steps, kerbs and most steep inclines. It is small enough to operate inside buildings, down the aisles of an aircraft, in buses and trains. Terrier can locate and move, or destroy, suspect devices from ground level (including under a car) up to a height of 1.7 metres.
Terrier is battery-operated and has an endurance in excess of an hour during normal EOD operations. It is supplied with a powered telescopic arm, a grab and a storage box as standard. A newer, larger Maxi-Terrier ROV is now available.
