Line Following Competition

Line Following Competition

From our experience there are a lot of people who, firstly, would like an opportunity to learn how to program and it is a lot of fun to do so by building hobby automated projects. See below for some examples. Secondly, it is motivational and fun to be able to focus your efforts on a final goal, and this why we are hosting a competition in December, so that people can get motivated and come out and play. We at the O’Town are very much focused on diversity and to give everyone the chance to be part of this competition we will be hosting some full day workshops in November. These workshops will be free, but you will be required to buy your own hardware. We will provide links on where you can buy the hardware and we are also willing to buy it for you, but we will require cost to be paid up front before a certain date. Again see below for information. Prizes will be give out for the competition and these will represent diversity. What these will be is not set in stone yet, but some examples could be: prize for the youngest person; prize for the fastest female team; funniest looking robot and of course the fastest of the overall competition.

Registration is required for this competition, so please fill out the google forum. By filling out the form you give the O’Town the right to keep your email and send you information related to the compeition.

What is a Line Following Robot I hear you asking?

A line following robot is an autonomous robot which follows either a black line on a white background or vice versa. The robot must be able to detect particular line and keep following it. Depending which sensor is detecting which background (white/black) the robot needs to move in different ways, as is depicted in the image on the left.

Rules for the Competition

  1. Teams can be from 1 – 4 people
  2. Line Followers must be self contained, and not externally operated by wire or by remote radio control during the race. 
  3. Except for the battery pack, the handler shall not make any addition, removal, replacement or change to the hardware of a Line Follower during a contest. It is however permissible to make minor repairs
  4. A Line Follower shall not exceed 22 cm in overall length, 16 cm in overall width and 13 cm in overall height
  5. Before commencement of normal racing, each racing team can test the racing environment on site
  6. Line Followers shall start anywhere within the defined start-finish area, and shall go in the specified direction.
  7. Within the given performance time, the handler is allowed to replace batteries and/or upload new program parameters to the Line Follower.
  8. The Line Follower shall have a specified maximum number of attempts to run the track within a stipulated time limit (typically 3 to 5 minutes and from 2 to 3 attempts to be decided by the Organiser on the day of the race). If the performance time limit is reached and the Line Follower is in the midst of a run, the Line Follower will be allowed to complete the run and the lap time will be valid if the run is successful.

Denisa is our youngest superstar. At the age of 14 she is already a wizz kid at programming, and playing around with hardware. Her inspiration comes from her dad, who is a techy guy himself. She will be teaching our Junior workshop, and we are happy to have her at our side.



Tom has been getting into programming and building hobby automated projects over the last year. He is now building and programming his very first line following robot, and is looking forward to sharing his learning's with others.


Clio has been running many different workshops over last 7 years aimed at anyone who has the willingness to learn. She loves seeing people's reaction when they finally get something to work.
