Engineering students from VIT design a Line-following robot

Pallavi Bhamare and Ayush Kumar, final year students of Electronics Engineering at Vellore Institute of Technology, have designed a robot which can climb stairs and do small tasks like exchanging packets and letters between two offices. This line-following robot has been developed using Artificial Neural Network (ANN)-based technology and follows a white-lined track.

These robots have been fitted with 9 sensors which is used to collect input and make decisions. They designed the robot to learn the mapping between inputs and control decisions such as turning left, right and straight ahead from a human trainer. The robot is 55-cm high and 18-cm wide robot and cost about Rs 25,000 to build it. It can carry a load of up to 1.5 kg and climb steps of up to 15 cm height. Its source of energy is a rechargeable battery.

Pallavi worked on the ANN algorithm using the MATLAB software and Ayush took care of the robot's mechanical design. Their mentor, Dr Mathew Mithra Noel, guided them through the process.

The young inventors say that their next step is to invent an unsupervised learning robot.
