INNOVATION: 3D Printing Emerging As Game-Changer In Many Industries
Even as designers’ creativity comes alive with 3D-printed clothes and jewellery at a fashion show, elsewhere in the world a cancer-ridden bird stays alive with a 3D-printed bill, and a new-born child gets a new lease on life with a 3D-printed skull. Indeed, the emerging applications of 3D printing are awe-inspiring and packed with hope

TRENDS: How Lidar Is Enabling Autonomous Drones
Lidar, which stands for light detection and ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure variable distances to the Earth. These light pulses—combined with other data recorded by the airborne system—generate precise, three-dimensional information about the shape of the Earth and its surface characteristics. The information can be highly useful, as described below

PROJECT: A Futuristic Wearable Health Monitoring Ring
While working on an IoT based data acquisition system using health monitoring sensors, we started visualising this health monitoring system, which could be worn like an ornament in our day to day life. We thought, what if it’s a smart device that can store real-time data, creating a platform for both monitoring and evaluation for a doctor while we are in our home itself. It could have an SOS feature, which is one of the main issues in India where people are unable to contact hospitals or doctors well in time

INTERVIEW: “Machine Vision For Object Manipulation Had To Be Treated Differently” — Gokul N.A. And Nikhil Ramaswamy, Co-founders, CynLr
When we look at an object, our brain immediately knows how to pick it up—whether to use a hand, or just fingers, or both the hands! This sort of intelligence is lacking in current robotic systems. CynLr, a Bengaluru based robotics deep-tech startup, is now solving this problem using a unique approach. In an interview with EFY, Gokul N.A. and Nikhil Ramaswamy, Co-founders of CynLr, talk about how they are working towards achieving such visual object intelligence for industrial robots
