    - Autonomous sentry robot on South Korea–North Korea border, detects intruders
Helps in Disaster Management
- Robots can enter disaster-affected areas where humans cannot safely reach.
- They can be used for search and rescue operations, debris removal, firefighting, flood monitoring and damage assessment.
- Robotics can improve the speed and accuracy of disaster response.
  - Search-and-rescue robots in earthquake rubble, nuclear/chemical hazard zones.
  - Snake robot (CMU) — navigates rubble in earthquake zones, locates survivors.The Carnegie Mellon University (CMU) Biorobotics Laboratory developed highly agile, multi-jointed snake robots to slither through confined, hazardous debris.
Transforms Healthcare
- Robotics has important applications in surgery, rehabilitation, elderly care, hospital management and diagnostics.
- Robotic surgery allows minimally invasive procedures with greater precision.
- Robots can also assist in physiotherapy, patient monitoring and delivery of medicines inside hospitals.
  - Da Vinci robotic surgical systems to increase the scale and efficiency of minimally invasive surgery.
  - TUG robots — autonomous hospital robots delivering medicines, meals, lab samples
  - Moxi (Diligent Robotics) — hospital logistics robot assisting nurses in US hospitals
Supports Agriculture
- Agricultural robots can help in sowing, spraying, harvesting, weeding, soil monitoring and crop surveillance.
- They can reduce labour shortage and improve efficiency in farming operations.
- Precision farming using robotics can reduce the use of water, fertilisers and pesticides.
  - Drone-based spraying, automated harvesting, pest detection — addresses farm labour shortage
  - Drone spraying under PM Kisan Drone Yojana

Strengthens Space Exploration
- Robotics is essential for space missions because many tasks are too risky or impossible for humans.
- Rovers, robotic arms and autonomous systems are used for planetary exploration, satellite servicing and sample collection.
- Robotics helps in expanding scientific knowledge of space.
  - Vyommitra (India) — Vyommitra is a human-like robot developed by ISRO to serve astronauts during manned space missions.
    - During the mission, Vyommitra will operate control panels, monitor the cabin environment, and send real-time data to ISRO’s control centre
  - The Chandrayaan-3 mission’s Pragyan rover solidified India’s capacity in autonomous robotic exploration by successfully traversing the unexplored lunar south polar region.
  - Curiosity & Perseverance Rovers (Mars) — AI-enabled autonomous navigation, rock drilling, sample collection; Perseverance collected first Mars rock cores for future return mission
Improves Public Service Delivery
- Robots can be used in sanitation, waste management, sewer cleaning, crowd management and public safety.
- For example, robotic machines can reduce manual scavenging and protect sanitation workers from unsafe conditions.
  - HomoSEP Atom is India’s septic tank and manhole cleaning robot
- This makes governance more humane and technologically advanced.
Supports Elderly and Disabled Persons
- Assistive robots can help elderly persons and persons with disabilities in mobility, communication, rehabilitation and daily activities.
- This improves independence, dignity and quality of life.
  - ReWalk Exoskeleton — wearable robotic suit enabling paraplegic patients to stand, walk, and climb stairs

Important for Environmental Management
- Robots can monitor pollution, clean water bodies, inspect pipelines, detect forest fires and assist in wildlife conservation.
- They can collect data from difficult terrains and help in evidence-based environmental governance.

Challenges Associated with Robotics

Job Displacement
- Excessive automation may replace low-skilled and repetitive jobs, especially in manufacturing and services.
- This can increase unemployment if workers are not reskilled.
  - Foxconn had replaced 60,000 workers with robots in Chinese iPhone assembly lines
High Initial Cost
- Robotics requires high investment in machines, software, maintenance and skilled manpower.
- Small and medium enterprises may find it difficult to adopt robotics.
Skill Gap
- Robotics requires trained professionals in engineering, coding, AI, electronics and maintenance.
- Lack of skilled workforce can slow down adoption.
Dependence on Imported Technology
- Many advanced robotic components such as sensors, chips, actuators and precision hardware are imported.
- This can create technological dependence.
Ethical and Legal Issues
- Robotics raises concerns related to accountability, safety, privacy and misuse.
- For example, autonomous weapons and surveillance robots can create ethical dilemmas.
Cybersecurity Risks

Way Forward

Promote Indigenous Research and Development
- Greater investment is needed in robotics research, AI, sensors, semiconductors and advanced manufacturing.
- Collaboration among government, industry and academia should be strengthened.
Develop Skill Ecosystem
- Robotics should be integrated with technical education, ITIs, engineering colleges and vocational training.
- Workers must be reskilled to adapt to automation.
Support MSMEs
- Affordable robotic solutions, subsidies, shared automation centres and technology support can help MSMEs adopt robotics.
Strengthen Regulation
- Clear rules are needed for safety, liability, privacy, autonomous systems and ethical use of robotics.
Encourage Start-ups
- Innovation hubs, incubation centres and funding support should be provided to robotics start-ups.
Focus on Socially Useful Robotics
- Robotics should be promoted in sectors such as sanitation, healthcare, agriculture, disaster management and disability support.
- This will ensure that technology serves human welfare.

Robotics is a transformative technology with the potential to improve productivity, safety, healthcare, agriculture, defence and governance. However, its adoption should not be seen only as automation, but as a tool for human welfare and sustainable development. A balanced approach involving innovation, regulation, skilling and ethical safeguards is necessary to ensure that robotics becomes inclusive, safe and socially beneficial.
