Robot that can end India's manual scavenging
Bandicoot: Robot replacing manual scavenging
The Greater Hyderabad Municipal Corporation (GHMC) has procured a manhole-cleaning robot called 'Bandicoot', which would help end the practice of manual scavenging.
Trial run of Bandicoot
The Supreme Court has issued guidelines to all Urban Local Bodies in the country to have "technology adopted methods" for cleaning manholes and septic tanks.
Bandicoot has two structures. One is the robotic unit with an arm and four legs that enters the manhole and handles the cleaning operation. The other is a control panel unit that stays outside the manhole with the person controlling or monitoring Bandicoot.
The robotic unit has a fixed, waterproof, night-vision camera that transmits 4K resolution videos and images in real time, even in the presence of water.
Various sensors help Bandicoot measure different environmental parameters like manhole dimensions, material and chemicals inside the manhole, humidity, temperature and so on. The robotic arm has five degrees of freedom with 360-degree movement capacity. A bucket unit of 18 litres capacity is attached to collect waste.
For non-standard manholes, the semi-automatic control is brought into play. The human being controlling the robot can use the control panel that has a display screen to position Bandicoot inside the manhole. Cleaning is done automatically.
