The Kerala-based robotics startup, which began with machines to clean sewers, is growing in size and scope while doing social good
Nearly two decades ago, as a sanitation worker for the Indore Municipal Corporation, Govind Bherve would routinely lower himself into manholes, and clean the sludge and muck out with his hands. Often, he’d say a silent prayer before jumping in, for he didn’t know if a reptile or a rodent would be lurking inside; during work, he was dunked in filthy sewage water gushing out of the pipes. “We spent close to 30 minutes inside a manhole every day, and continued with our 8-10 hour shifts thereafter,” says Bherve, now 35. “It was so dirty that I got skin infections regularly.”
Even outside work hours, Bherve was called to attend emergencies, say, when a plumbing line choked at midnight. “We’d just take off our clothes and go into the manhole,” he says. “Protective suits the, par usme dum ghut ta tha [there were protective suits, but they would suffocate us].”
Bherve still works as a sewage worker with the municipal corporation, but his life has taken a U-turn. For some time now, he hasn’t set foot inside a manhole; instead he operates a robot that opens the manhole cover, goes deep into it and scoops out the sewage with its multi-functioning arm, just like a human. “There’s a screen attached to the external unit that shows us the nature of garbage inside, helping us manoeuvre the arm efficiently; it also detects if there’s noxious gas inside,” he says. “This robot has made our lives so much easier.”
Christened Bandicoot, the robotic scavenger that has brought Bherve such joy is the brainchild of four engineers—Arun George, Nikhil NP, Rashid K, and Vimal Govind MK—from Kerala, who seeded the idea in 2015, while studying in MES College of Engineering, Kuttippuram, in Malappuram district.
It started with designing for the college project a first-generation powered exoskeleton, a wearable mobile machine called the Iron Man suit, that could lift weights and facilitate military supplies in remote areas; a fine-tuned version the following year was put together to help amputees walk, and a paper on it won the best concept award at the International Conference on Mechatronics and Manufacturing held in Singapore.
