Hazardous-Environment Robotics: Where Physical AI Meets India's Sanitation and Refinery Safety Crisis

The human cost driving the category

The numbers behind manual sewer and septic-tank cleaning in India are the real argument for hazardous-environment robotics, and they are stark:

• Between 2019 and 2023, the government recorded 377 deaths from sewer and septic cleaning, with 63 deaths in 2023 and 52 in 2024.
• Parliamentary data separately puts the toll at 65 deaths in 2023, 54 in 2024, and 47 in 2025.
• In the first four months of 2026 alone, 52 people died cleaning sewers and septic tanks.
• A 2022–23 audit found that over 90% of these deaths occurred without protective gear.
• Advocacy group Safai Karmachari Andolan puts the real toll far higher — at least 1,760 deaths since 1993 — arguing official figures undercount the practice by classifying it as “hazardous cleaning” rather than manual scavenging.

This is a body-count-reduction story, not a labour-replacement story — which is a far stronger case for procurement and policy than most physical AI pitches manage.

Genrobotics: the deployed, at-scale example of this trend

While Scout is a demo, Genrobotics — the Thiruvananthapuram-based deep-tech company building Bandicoot — is the closest thing India has to a hazardous-environment robotics category leader already operating at national scale.

Bandicoot, by the numbers

• Operational in 19 states and 3 Union Territories.
• 300 robots across 37 sites have cleaned over 6,000 manholes, with a stated goal of reaching all 5,000 urban local bodies in India.
• Cleans up to 12 manholes in 8 hours — a task that otherwise takes 2+ days and 12+ workers manually. Over 3,000 sanitation workers have been trained to operate it.
• Rajasthan alone deployed 32 units across 23 cities, cleaning 50,494+ manholes since 2022 at 20–25 manholes per unit per day. Chennai's Bandicoot Mobility+ units cleaned 5,000+ manholes and stormwater drains in their first year since April 2024.
• In July 2026, HLL Lifecare Limited — a Government of India enterprise under the Ministry of Health and Family Welfare — signed an agreement with the Mahatma Phule Backward Class Development Corporation (MPBCDC), a Government of Maharashtra undertaking, to supply 100 Bandicoot series robots for manhole cleaning across municipalities statewide, described as one of the country's largest robotic sewer cleaning projects to date.

The public-sector procurement engine behind the scale

The Maharashtra deal is a useful window into how this category actually scales in India — not through direct-to-municipality sales alone, but through central PSUs acting as implementation partners for state governments. HLL Lifecare, better known for pharmaceuticals and medical devices, is using its Sustainable Projects Division to route Genrobotics' Bandicoot fleet into Maharashtra's municipal sewer networks, with the state's MPBCDC as the receiving agency. The arrangement is designed to enable faster emergency response and eliminate manual entry into manholes across the state's municipalities, while improving safety, dignity, and working conditions for sanitation workers.

This model — a national PSU as delivery vehicle, a state development corporation as end-user, and Genrobotics as manufacturer — is a template that mirrors the Rajasthan and Chennai deployments, and signals that hazardous-environment robotics is being absorbed into standard government procurement machinery rather than remaining a pilot-stage novelty.

The category is expanding past manholes — into refineries

The same “zero human entry” logic Scout pitched for refinery monitoring is already a formal, contracted engagement for Genrobotics. Indian Oil Corporation Ltd. (IOCL) — which operates 11 of India's 23 refineries — partnered with the company to build robotic tools for internal tank cleaning and inspection, targeting 100% no-man entry across its network.

Genrobotics' oil & gas fleet, purpose-built for this category:

• Extreme Bandicoot — confined vertical structures (oily-water sewers, stormwater drains) with toxic gas sensing and a hydraulic arm.
• Wilboar — a heavy-duty rover for tunnels, ducts, and pipelines in low-oxygen environments.
• Draco — described as the world's first amphibious drone for in-service cleaning and inspection of live crude oil storage tanks, enabling zero-downtime maintenance.

All three carry flameproof, explosion-proof variants (PESO certification in process), with ONGC, HPCL, BPCL, and IOCL among the division's clients.

And it's spreading to canals

In March 2026, the Thiruvananthapuram Municipal Corporation commissioned Genrobotics' G-SPIDER — a cable-driven parallel robotics system — for human-free canal cleaning under Swachh Bharat Mission-Urban 2.0, targeting canal sections where restricted vertical clearance and continuous water flow make conventional maintenance dangerous. Same pattern: find a confined, toxic, or structurally hazardous space humans are entering, and remove the human.
