As soon as we come across the word robot, we tend to imagine a metallic structure with arms and legs carrying a human-like appearance and running errands for our help. However, in actual terms, it’s just a machine operated externally or through a controller embedded within and doesn’t necessarily look like a human. Technically, robotics is a branch of Science and Engineering which deals with designing, constructing, and operating robots as well as computer systems for their control, sensory feedback, and information processing.
Interestingly, the concept is almost as old as the hills with the first robot dating back to 350 BC, built in the form of a mechanical bird, by a Greek mathematician named Archytas. Although the term was coined ages ago, the actual potential of the fully autonomous robotics was realised in the second half of the 20th century.
The term Biometrics is a combination of two words- bio i.e. life and metrics i.e. measurement. It refers to the metrics related to the human characteristics, particularly the physical and behavioral aspects. The technology is implemented to measure and statistically analyse people’s biological information mainly for their identification, access control or surveillance.
Every individual is unique and carries a separate identity in the form of traits like fingerprints, hand geometry, iris recognition, voice, etc. Biometric verification is gaining a lot of popularity among the public security systems as well as in the commercial market.
Nanotechnology is basically defined as the engineering of functional systems at the nanoscale, which is about 1-100 nanometers. Interestingly, one nanometer is a billionth of a meter or 10-9 of a meter. In other words, it refers to the process of building items from the bottom up with atomic precision so as to avail benefits like the lighter weight, higher strength, and greater chemical reactivity. Today this technology is being used on a large scale. Right from the light-weight cell phone screens to light car bumpers and radiation resistant sunscreen to stain repellant clothes, everything contains the nanotech effect. Even the wearable devices play a significant role in exploring the potential of nanotechnology to a considerable extent.
