The largest robot in the CALIBER® family, the CALIBER MK4 offers unprecedented towing and dragging capabilities coupled with speed, agility and dexterity—all at an affordable cost.

The MK4 is the most powerful of all CALIBER robots, with a lift capacity of 200 lbs (90 kg). Its Command & Control Unit provides automatic preset positioning to facilitate rapid deployment; and a 3D avatar that offers real-time positional feedback on the actual position of the robot.

Based on recommendations by bomb technicians, the robot’s modular design allows for reduced maintenance costs through easy platform upgrades, field repair, and parts replacement.
