Unmanned Vehicle Based on BMP-II platform (VERY OLD NEWS)
http://drdo.gov.in/drdo/pub/nl/2009/aug09.pdf
The first prototype of Unmanned Ground Vehicle on BMP II vehicle platform has been developed by Combat Vehicles Research & Development Establishment, Avadi, Chennai. The prototype consists of Drive-by-Wire (DBW) system which includes electromechanical actuators and drives for the driver interfaces such as acceleration, brake, gear shifting, steering, clutch, parking brake, etc.
The DBW system is controlled by a PXI-based controller in the remote vehicle and receives commands on wireless LAN from a lab view-based GUI located in the base station. The position feedbacks from the encoders on the steering actuators and from limit switches on the gear shift levers are obtained at the base station for accurate control. The clutching and gear shifting operations have been combined in the GUI, rendering the advantages of an automatic transmission to the conventional power-pack. Remote switching on the engine is also built in the controller.
The unmanned BMP was demonstrated to Dr A Sivathanu PIllai, Distinguished Scientist, and Chief Controller Research & Development (NS &ACE), on 25 May 2009.
The signals from the engine, like engine rpm, vehicle speed, etc are acquired by a data acquisition card and displayed in the GUI. The electromechanical actuators for the BMP II have been designed in such a way that the driver's accessibility to all the control pedals is not affected. The reverse effect on the actuators due to the
manual override was considered during the design and selection of electromechanical actuators.

LRDE SUPPLIES WAVEGUIDE ANTENNA TO POLAND - 2001
http://drdo.gov.in/drdo/pub/nl/june2001/waveguide.htm
The Electronics & Radar Development Establishment (LRDE), Bangalore, has sucessfully designed, fabricated and evaluated an X-Band Slotted Waveguide Array Antenna. It is rugged and compact with high power handling capacity and efficiency. It meets all the electrical, mechanical and environmental specifications.
Dr VK Aatre, SA to RM, handed over the antenna to Dr Wisner, Dy Director, PIT, Poland, during Aero India - 2001 exhibition. Some major design features of the antenna are:
State-of-the-art computer-aided design
Use of proprietary and copyrighted CAD software packages, like COBRAS, COBICS and COBRAS-DC-
Compact architecture using non-standard reduced height waveguide dimensions
Planar magic tee junctions for compact monopulse comparator network
Elliptical profile for the effective utilisation of the available area
