DRDO developing exoskeleton for the Indian soldiers posted in high altitudes

For the Indian soldiers, such futuristic technology can help in moving around in the minus 30-40 degrees Celsius temperature along the Line of Actual Control (LAC).

The exoskeletons are rapidly emerging as part of the modern troops body gadget and Armed Forces may be keenly looking forward to the culmination of this project, far sooner than many others still within the Defence Research and Development Organisation (DRDO) Lab environmentMultiple R&D in the bio-engineering and electro-medical technology are carried out by DRDO and this is done so that technological advancement reaches the soldiers. 

Exoskeletons can be worn over a regular uniform or combat gear so that a soldier’s strength is fully augmented. And this helps in ensuring soldiers who are on patrol duty in high altitude terrains wear leg-gear which assists in walking in the snow. This then reduces fatigue and exhaustion which is faced by the soldier in a thin oxygen climate.

“AD-hoc projects like Exoskeletons are ideally suited to be handed over to the IITs and the private sector companies as it does not require much resources. In DRDO, all resources and manpower are being used, and they have no sanctions from the services, hence there is no urgency to complete the R&D,” suggested the officer quoted about on condition of anonymity.

What is the current status of Exoskeletons?

DEBEL is the nodal lab doing the R&D on this and is utilizing in-house expertise in disciplines of Biomedical/Biomechanics, actuators and control systems.

Response from DRDO

Last December (2020), in response to a question by Financial Express Online, DRDO had said that, “For enhancing Indian soldiers’ performance in military scenarios, several configurations including lower/upper extremity, and full-body exoskeletons are being developed and several DRDO labs are involved in this.”

In June 2021, responding to Financial Express Online on the current status of Exoskeletons, DRDO in an email response says: “DRDO has been entrusted with a requirement to augment the soldier’s capability during logistics activities performed by the military. Therefore, the biomechanical characteristics of the soldier during various logistics activities such as transportation of goods, ration, ammunition etc., through diverse terrain, for long distances with their complete military gear has been systematically captured and analyzed.”

It goes on to add, “Exoskeleton systems are being designed and developed for specific military logistic applications involving bending, lifting of payload, walking with payload anterior to the body, and unloading the same. Various concepts and configurations are being designed and developed currently. DRDO has been progressing on the different design approaches to build an augmentative exoskeleton for the Indian Army. There have mainly been two schools of thought/approaches for the design of augmentative exoskeletons, namely passive/unpowered augmentative exoskeleton and powered augmentative exoskeleton. The passive exoskeletons use passive elements such as springs, dampeners etc., to transfer the payload to the ground, however active exoskeletons not only transfer the payload to the ground but also impart energy through the actuators resulting in reduced energy consumption by the soldier.”
