It has already been a year since we finished building our autonomous tricycle project. (We totally forgot we have signed up this blog at which we should update up progress of the project while we were building the tricycle.) But thankfully, we took some pictures during our designing, manufacturing and testing process. Today, we decide to share our experience on this website with anyone who also like to build one for themselves.
The very first thing is the idea. However, aside form idea, we believe passion is the most important thing that drive us through the whole process.
This is a review of what we have done last year. So as you guys can tell, the tricycle in the background is our final lovely baby and it is now passed on to the next follow up team who will make it better.
The ideas that we have in mind are to
In fact, at the end of the project, we reached our first goal and changed our second and third goal to "lane tracking".
During the process, (we started this project from January, 2018 and ended it at June, 2018) we changed our goals multiple times but its our passion and our believing in ourselves that we can build an autonomous platform, so that we can keep working on this project in our spare time even though we all have our personal working job at weekdays.
Back to the topic, the reason we chose to build a tricycle rather than a bicycle or a car is that tricycle is the simplest controlled vehicle platform that can also carry multivarious sensors on it. The bicycle is hard to balance on autonomous mode and a car is too hard (and too expense) to build. Therefore, a tricycle seems to be our best choice on the table.
After having ideas, detail designing is an important next step.
