The Combat Vehicles Research and Development Establishment (CVRDE), Avadi-based (near Chennai) DRDO lab, is warming up to take two of its unmanned ground vehicles (UGVs) for summer trials in the next two months. CVRDE director Dr P Sivakumar told Express that the UGVs – Muntra-N (designed for NBC – Nuclear, Biological, and Chemical reconnaissance) and Muntra-M (designed for mine detection missions) – are currently undergoing lab-level trials at Avadi. DRDO had exhibited Muntra-S (meant for surveillance) during the DefExpo, 2012, and the scientists say that the vehicle has already completed the desert trials successfully. Muntra stands for Mission Unmanned Tracked. Sanctioned with a seed money of Rs 60 crore in 2007, the project consists of four vehicles, with three in the unmanned role and the fourth one in a manned mode (Muntra-B), doing the base control duties. “Muntra-B will be common for all missions depending upon the role. In 2012, during the field trials, Muntra-S operated at very high temperatures in Rajasthan deserts. We tele-operated Muntra-S from a distance of 5 km and it tracked a tank further at a distance of 12km. The radar has an instrumented range of 18 km. During the trials, we undertook day and night surveillance and tele operated the vehicle back to the base as well,” Dr Sivakumar said. In 2013, the CVRDE began the int egration of UGVs Muntra-M and Muntra-N with a series of lab-level tests. The UGVs can perform in tele-operated, autonomous and manned modes. “All vehicles are based on the battle proven BMP II class of tracked armoured vehicles. In addition to being an all terrain vehicle, these vehicles have an inherent amphibious capability, thus making a UGV based on these vehicles a highly potent and versatile unmanned platform,” he added. Currently, the DRDO and the Army are holding talks on the UGV philosophy. The Army is already using manned vehicles for NBC reconnaissance missions and the DRDO is strongly pitching with the idea of having UGVs as well for the said roles.
