In big cities, apart from gleaming glass buildings and fast cars, it is quite common to see a manual scavenger gingerly stepping into an overflowing manhole to unblock it. He trowels out the sludge — of kitchen waste, plastic and human excreta — while inhaling toxic gases and wading through infected liquid waste. Although a ban on this practice was imposed way back in 1993 it still continues unaffectedly. Thus, to put an end to this, a Thiruvananthapuram-based start-up Genrobotics has come up with a solution. Its four-member team has built a 50-kg robot, named Bandicoot, which can clean up a manhole in 20-45 minutes. A manual attempt usually takes around three hours.
