The DRDO installations at the DefExpo 2020 in Lucknow have proven to be among the largest crowd-pullers. The Anti-Satellite (ASAT) missile — successfully tested last year, making India the fourth country to successfully attack satellites — is attracting a lot of attention. So are the Akash Missile systems and the tanks. However, the installations are not restricted only to its defence systems — it has also brought some of its latest technologies that will be used by the country’s armed and paramilitary forces not just in combat zones, but also in counter-intelligence, surveillance and sanitisation operations.
 
What
  1. While some of the technologies displayed are ready to be inducted, others are still at the trial stage, and a few others are still at the proposal stage.
  2. Among the installations is that of its latest Daksh robot, also called the Unexploded Ordnance Robot
  3. The Daksh Defuser, DRDO scientists said, is the world’s first machine that can not only handle unexploded bombs remotely, but can also defuse them
  4. Scientists said that the machine can be operated from a distance of up to 2 km, and while one arms of the machine can extricate a bomb from the ground, another arm can defuse or cut it.
What is Daksh?
  1. Daksh is an electrically powered Remotely Operated Vehicle (ROV) designed and developed by the Indian state-owned Defence Research and Development Organisation (DRDO) at the Research and Development Establishment (Engineers), Pune, India.
  2. Primarily designed to recover improvised explosive devices (IEDs), ROV Daksh can safely locate, handle and destroy all types of hazardous objects.
  3. The DRDO transferred its ROV technology for production at Dynalog, Theta Controls and Bharat Electronics.
  4. In 2010, the Indian Army placed a limited-series-production order for 20 Daksh vehicles after extensive trials, testing and acceptance. 
  5. The first batch of five ROV Daksh was delivered to the Indian Army in December 2011.
  6. Daksh will serve bomb disposal units (BDU) of the army, police and paramilitary forces in handling IEDs and other hazardous materials. The Indian Army has the requirement for 100 ROVs.
  7. The major task carried out by ROV Daksh is IED handling. The IED handling equipment scans, handles and removes hazardous objects.
  8. The water jet disrupter fitted on the vehicle can safely diffuse IEDs. The vehicle can lift, drag and tow suspected objects away from the area.
  9. The onboard X-ray unit scans horizontal and vertical planes. The unit is equipped with real-time imaging facility with zoom in / out and multiple auto snapshot creation facility. 
  10. The image processing software allows the users to alter brightness, contrast, sharpness, blurring, negation and mirror settings.
