Bexley Grammar School 2017

Swechha Kansakar and Natasha Sidhu


We wanted to use Mark Evision as a platform to create a functional robot which could be programmed to do a number of useful tasks around the home. The Mark evison foundation was a great way to made this project work as it was completely independent which will allow us to research outside of the school curriculum to learn new skills and explore areas of Engineering and Computer Science which fascinated us.

Starting off
We started the project off by producing a detailed report outlining our design for the robot, including the financial costs and risks associated with the construction. This report gave us an idea of the costs and time frame we had to complete the project which helped simplify the project into manageable sections.

Ordering parts
In July, we got to work by first ordering most of the components of the robot on the electrical side such as the raspberry pi. We first had to familiarise ourselves with the device and the coding language as we had never used it before.

Building the robot
A few weeks and online tutorials later, we started ordering material to create the physical robot such as meltable plastic, wood. This stage was mostly experimental to see how easily the products could be adapted for our design.
Our main design consisted of a plywood base surrounded by a meltable plastic however, we encountered several difficulties. It was difficult to keep the plastic at the same thickness therefore some parts of the robot were weaker than others. Therefore, we thought it would be better to use timber for the sides as well. This made the robot sturdier. We made precautions to ensure the robot will be balance this is shown in the image below.

Motor Code
The most difficult aspect of the task was configuring the motors with the code. We had to assign pins to each motor and then we were able to take this information and put it into a while statement.
