I'm not quite sure if this is the correct forum or not and I would like to apologise in advance if it is not, I'm new here! So basically I'm in my final year at school, I'll be attending University in October all being well, but before I get there I have to sit my final exams, and where I am, in Ireland these exams are called the Leaving Certificate. As a part of my leaving certificate I chose Engineering as a subject in school and as a part of the assessment we are required to make a project to be submitted along with a written examination and a design folio relating to that project. But anyway what I'm here to ask is how do I make this project work. We are given a brief and have to make a project in accordance with that brief and this year's brief was in relation to theme parks and thrill rides etc, so anyway the making of the actual parts and assembling the piece in real life isn't the problem for me its the part concerning the motors where I am stuck. I'll attach a photo with this post of the design I have and if anyone could explain how to get that arm swinging around 360 degrees using motors that would be great, any input is appreciated. Thank you!
