Indigenous Robotic Solutions For Underwater Inspection
Without proper care and maintenance, decades old infrastructure is often subject to catastrophic failures, causing loss of life and property. This makes it necessary to regularly assess and monitor assets, which is a complicated task especially for subsea structures like dams, bridges, ships, oil and gas platforms. This led to the foundation of IIT-Madras incubated startup Planys Technologies in 2015 with an aim to develop customisable robotic inspection and survey solutions for both onshore and offshore submerged structures
