Remote Controlled Dozer (RCD)

Remote Controlled Bulldozer (RCD) designed while working for BEML, India.

Remote controlled dozer is a Disaster management equipment and is built for the first time in India in 2001-2002.The system allows operator to perform all vehicle functions from a distance from any position to deploy in any hazardous environment without any possibility of the operator being getting hurt. It is an unmanned equipment remotely operated with a trans-receiver. The dozer is meant for removing nuclear wastes and debris after an earthquake. I have designed and developed the mechanical system and the electronic controls have been developed by another group. It is powered by 324 hp@2000 rpm engine. It weighs about 34930 kg. The remote control system has a range of operation of 60 m under normal operating conditions and 300 m with clear line of sight.
