Last week we made some wheels on the program Solidworks. Then we printed them in 3D.
Before we could put the electronic card  we had to modelize the entire rover on a "modeling" program called solidworks, which despite many quite frankly stupid mechanics, is still a rather good program. But we quickly realized that we weren't going to have enough time to finish the entire rover so we decided to only do the really important pieces which were the wheels and the frame. So after having finished the frame (which we decided to entirely redo), We realised that we were going to need a wheel that could turn so I figured we either use a axel to make the wheel turn, but I figured that it would be easier to use a free wheel. So I spent about an hour working on it until I was told that we didn't actually have to make one because we could just get one from a store. So that was a GIANT waste of time. So after that Lucas did the two back wheels which are now going to print in a 3D printer, which is going to take a few hours. So while we were waiting for that we had to imput an electronic card into the rover to give it a "brain". But before fixing the card to the rover we had to make a program that would enable our dear little rover to get out of a tight spot if it ran into one. To make the program we needed a program called ROOBY which is a thing that enable us to tell our rover what to do by inputing certain variables, those "variables would be two mustache sensors which would be triped whenever the rover hit a wall. ROOBY would let us tell our rover to do stuff like: spin both wheels backwards and that would make the rover reverse  ,spin one wheel backwards and forward which would turn the rover one way or another depending on which wheel went forwards and which one went backwards. but prior to doing that we had to connect the card to the motors, the moustache switches and four batteries. I can't explain how to use ROOBY because it would take too long to expain so I'm just going to put a link to it's user manual which you will find here if you have downloaded ROOBY: C:\Program Files (x86)\Rooby\Help\index.html .









We plugged the card to two motors, two switches, and a four-batteries pod. We are now making a program on Rooby to upload it to the card, in order to make the rover go forward, backward, to make it turn...
To have an idea of the final product, we are using an already made structur and uploading the programs we made to test them
