CE 1.2 Project Background
CE 1.2.1 Characteristics of the project
I was working in a team and our concerning field was the motorcycles those have been
widely used as the mode of transportation in most of the developing countries. Mostly, the gear
shifting control of the motor bikes were conventionally a manual process. We developed a model
that can be helpful in covering development of the indigenous gear changing/shifting system for
most of the standard bikes. We managed to develop a project that will allow automation in the
clutch system without altering the manual gear-shifting system through placing an additional
electromechanical system over the lever in manner to allow the gear shifting. I managed to keep
the budget of the project low as much possible through utilizing low cost microcontroller without
altering the decision-making control mechanism. We delivered the experiment on the motor
bikes ranging between 50 to 200 cc.

CE 1.2.2 Objectives developed for the project
Following objectives were developed by the team leader after asking the decisions of the
different stakeholders:
 To develop the design automatic transmission system
 To mathematically calculate the magnet’s dimensions that is about to be used
align with the gear ratio
 To program the Adruino program for the linear punching actuator and servo
motor in manner to allow the automation within the gear shifting system
 To deliver Analysis on the designed mechanism developed for the proposed
automated system
 To test and fabricate the designed mechanism
CE 1.2.3 My area of work
I had to work within the team in cooperative manner and manage the entire mathematical
calculation related to the ongoing research and design program. I analysed the existing model of
an automated manual transmission system and used the collected information for developing a
new automatic gear selection machine for the automobile. I was assigned to determine the
necessary constraints and measurement for the delivery of the project. I did the following
calculation for calculating the gearing speed range and vehicle:
If we consider the speed for first gear is 0km /h to 20km/h for second 20km/h to 30km/h
for third 30km/h to 45km/h and for greater than 45km/h take for the gear mashing.
