For the paddlewheels, we have implemented the correct 2D template in RoCo, but we're still working on the correct construction for the 3D model. Currently the two sides of the wheel are oriented flat face to flat face, instead of flap to flap as desired. We also need to code in tabs to connect the interfaces so that the final boat can be made completely of plastic film and electronics, and not use any tape.
In the next week, we will finish building the boat and wheels in RoCo, and also make the servo holders. By the end of the week, we want to have a physical boat made from the RoCo design.
