Indian Startup Builds Robots to End Deadly Tank Deaths

Every year, workers climb into India's industrial storage tanks to clean out toxic sludge and flammable residue, and every year, some of them never climb back out. A robotics startup near Chennai decided that in 2025, no one should have to risk their life for this job anymore.

Unibose builds robots that enter confined spaces so humans don't have to. Founded in 2016 by three engineers in Tamil Nadu, the company creates machines that clean tanks, rail wagons and sewers while operators control them safely from outside.

The death toll from confined space work in India isn't small or abstract. Workers regularly die from toxic fumes or oxygen deprivation in tanks and sewers, even though technology to prevent it has existed for years.

Unibose's robots enter through standard hatches and use cameras and sensors to give operators a live view of the work. The machines handle sludge, oils, fuels, chemicals and acids across the three main tank shapes that refineries use.

What makes them special is the safety certification. These are Asia's first robots certified to ATEX Zone 0 standards, meaning they can work safely in explosive atmospheres like the inside of a fuel tank.

The company builds everything in India at roughly half the cost of similar global systems. The robots cut cleaning time by up to 40% and slash operating costs by removing the need for rescue teams and special permits that human entry requires.

Unibose just raised $1 million total, including a recent round from O2 Angels Network and other investors, plus earlier seed funding from Tamil Nadu's government startup program. The company already has paying customers at IndianOil, CPCL's Manali refinery and Borouge in Abu Dhabi.

The Ripple Effect

Instead of selling robots outright, Unibose offers them as a service so contractors can hire the technology by the job. This model means smaller companies that couldn't afford to buy specialized equipment can still protect their workers.

The shift also creates new jobs training people to operate robots instead of entering dangerous spaces themselves. IndianOil recognized the innovation as its "Idea of the Year" in 2020.

Unibose plans to expand across India, the Gulf and Southeast Asia next, while adding AI tools for tank inspection and compliance reporting. Founder Manikandan Dakshinamoorthy frames the mission clearly: a robot can't replace humans everywhere, but it absolutely should replace them in places that kill them.

The bigger promise being tested here reaches beyond one startup: that Indian engineering can meet global safety standards and save lives at the same time.
