Building a Prototype of the Shooter

Todo: Attach to frame
We went back to our calculations, and noticed that the torque of the motors should suffice after all. (They are three times as strong as we need them to be).
Now we need a gear ratio of about 30:1 (see the calculations). To see which gear combinations might work, we made an excel table that calculates the ratio for each combination of wheels. By combining two pairs and multiplying their ratios we strove to get to the 30:1.
We decided to go for the 125:30 and 125:15, which yields a total ratio of about 35:1.
But instead of trying it out on our robot directly, we decided to build a new frame and attach the wheels and gears to it for testing purposes
Testing this we found out that it should be able to shoot the cubes. However the distance between the wheels is very relevant to the distance it can shoot.
The next challenge will be attaching this to our robot.
