This project is performed under the guidance of Prof. BJC Babu (Mechanical department- Bits-Pilani Goa Campus). This is registered as a Lab Oriented Project.
This project is also catagorised into two parts:
a) Developing electronic code to replace the traditional Ackermann steering linkage-
When a vehicle is taking a turn, the mechanical linkage (Ackermann linkage) present in most of the vehicles facilitates pure rolling at only one point. At other points on the turning trajectory, the vehicle slides, which is undesirable. The main aim behind this work is to facilitate pure rolling at more than one point on the turning trajectory. This is accomplished on a small scale by interfacing two stepper motors through a micro-controller. One of the stepper motors (ie- one wheel of the vehicle) is steered by the driver, and the other motor (the other wheel) rotates through the desired angle (that ensures pure rolling) which is governed by the micro-controller. Thus at every angle of the driver wheel, the driven wheel rotates at an angle that facilitates pure rolling. (for more information click here)
b) Modifying an existing Go-Cart to make it four wheel steer with electronic actuation-
An existing 2-wheel drive, 2-wheel steered Go-Cart is modified to make it four wheel steered. The rear wheels will be electronically coupled to the steering wheel through a stepper motor-microcontroller system that will ensure pure rolling condition to be satisfied when the vehicle is steered.
