In 2011, Professor Chouhan earned a place in the Limca Book of Records and garnered the Innovation Award from the former Chief Minister of Himachal Pradesh, Prem Kumar Dhumal. Acknowledged for his scholarly contributions, Professor Chouhan has represented India at international conferences and served as a speaker and jury member for academia and industries. His tireless efforts culminated in the Advanced Ballistic for High Energy Defeat - Bullet Proof Jacket (ABHED-BPJ) technology, exemplifying his dedication to national security and defence.

Professor Hemant Chouhan's research has significantly impacted the fields of unmanned and remote-operated devices, composite materials, and defence technology. He was instrumental in setting up the National Centre of Excellence – Personal Body Armour (CoE-PBA) at IIT Delhi for the indigenous design, development, manufacturing, and testing of ballistic and blast-resistant materials. This facility has been pivotal in advancing protective gear technologies, including developing Advanced Ballistic for High Energy Defeat - Bullet Proof Jacket (ABHED - BPJ).

Professor Chouhan's contributions to military automation projects include:

• the development of a low-cost bullet velocity measurement system,
• a tank target mechanism for war practice, and
• a Life-Buoy for water rescues.

Additionally, he converted an eight-seater electric boat into a remote-operated device, showcasing his expertise in enhancing security force capabilities and safety through advanced technological solutions.

Professor Chouhan amalgamates automation with composites manufacturing to develop superior products. By integrating low-cost automation techniques, he aims to enhance the efficiency and effectiveness of composite materials, leading to innovative solutions that significantly improve safety and performance in various applications. This holistic approach promises to set new standards in the field, particularly in developing advanced protective gear and automated systems for defence and civilian use.
