The Mk-4 is a small, highly capable, easy to operate, multi-camera, day/night observation and surveillance public safety robot. The MK-4’s omni-directional design allows it to operate the same no matter how it lands. Both the MK-4 and it’s Operator Control Unit have field replaceable batteries with real time voltage indication insuring they will always be ready no matter how long the mission. The MK-4’s super wide-angle, low light/night vision color cameras combined with its 7-inch color monitor give the operator an unmatched floor to ceiling view that is both detailed and easy to see, day and night. Indoors or outdoors, the MK-4’s powerful 4-wheel, direct drive motor system combined with its zero-turn radius can navigate tight spaces, push open unlatched doors and overcome obstacles like lose clothing insuring that it can get to where the operator needs it to be no matter the terrain.
