Write a research proposal of your interested topic in the following format:

Title: An investigation on the different lengths in between two mecanum wheels affecting the turning radius of a robot in 1 second  .

Question or Problem being addressed

In the future, cars can incorporate the mecanum drive to increase maneuverability while driving, reducing accidents. This can help people a lot for the handling of a the car will be greatly increased and thus they can easily make turns at awkward angles that are neccesary to get them out of harm’s way.

Goals / Expected Outcomes / Hypotheses

The larger the distance between the front and back wheels, the higher the radius of the turn the robot makes in one second

• Procedures: Detail all procedures and experimental design to be used for data collection

1) Build robot with a mecanum drive, adjusting the wheels as close as possible to each other
2) Insert program into robot to turn clockwise for 1 second
3) Place robot on Mahjong paper
4) Draw a straight line along the front width of the robot to make a ‘Starting Line”
5) Run program ensuring all motors on the left side are turning at 150 Rpm
6) After the robot has turned for 1 second according to the program, turn it off
7) Draw another line along the front of the robot to make a “Ending Line”
8) Extend the two lines until they meet
9) Measure the angle in between the “Starting Line” and the “Ending Line”
10) Record findings in Log book
11) Increase distance in between each wheels by 5 millimeters
12) Repeat steps 3 to 12 , only keeping the “Starting Line” and erasing the “Ending Line”

• Risk and Safety: Identify any potential risks and safety precautions to be taken.

- Robot ramming into a person foot. (Solution: Advise people to stay away during experiments)

• Data Analysis: Describe the procedures you will use to analyze the data/results that answer research questions or hypotheses
1) Look into the results collated.
2) Analyse the results via a table.
3) Determine if the experiment needs to be repeated.
4) If needed, repeat experiment and steps 1 to 3. If not needed, move on to step 5.
5) Post results of experiment to the blog .
6) Conclude the experimental phase by providing a conclusion to the investigation.
