Car story

We always thought of creating an automated driverless car which can be driven at variable speed and can be controlled from anywhere in the world.

To turn our ideas into reality, the four of us tried working on an electric car. The concept of the car was created by utilising Internet, mobile phone, laptop, C+ language programming and micro-controller board with ATMEGA 128 IC, under electrical control circuit.

It was a constant speed car. There were lots of hiccups before finalising designs of the “new car”. One of the key challenges was to control the car from a distance. For that we introduced a power electronics circuit that helped to control its operations remotely. To convert it into a multi-speed vehicle we installed a potentiometer in it. The size of the car prohibited the use of power steering. So, we designed a customised arrangement using a wiper motor which was attached to the Rack & Pinion set, and was inserted in the steering. This made the car complete.

Our car now works both on the auto and manual modes and has safety provi- sions such as a child-lock system.

The model has been successfully tested for 1000 plus kilometres. With time, we will modify its design, and operations, enabling it to detect pedestrian objects which will allow the car to slow down or stop suddenly.
