AMREL helped established the reputation of the Multi-function, Agile, Remote, Controlled Robot (MARCbot) as an effective warfighter tool. Integrated into the main control system, the radio was encased in the hardened material of AMREL's unique RCM, protecting it from interference of the internal electronics. The RCM enabled a small form-factor OCU solution, but didn't decrease the operating range. Being able to control the MARCbot from a safe distance was a major factor in this pioneering robot's popularity, which led to an even greater demand by the military for unmanned systems.
