We added tabs to the RoCo design so that the tape in previous boats will be replaced by mechanical connections. We also experimented with the settings on the Silhouette paper cutter and cut out half of one paddlewheel. In the next week we will construct a boat using the Silhouette Cameo to cut out...

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 t...

During the past week, we finalized the boat structure and began modelling the chassis in RoCo. Boat 10 was an attempt to make a faster boat by reducing drag. We flipped the battery and ESP8266 board on their sides and made the chassis narrow and long. However, when we tested it, the uneven weight di...

Our goal last week was to convert the boat chassis from an origami structure to a 2D template that was designable on RoCo. The template still needs to be made of one uncut sheet, like origami, so that water can't leak in through edges, but it can be folded from shapes other than a square. The first...

Boat 4 tested that the pinwheels would work with all the electronics in the boat since our last boat was too small to hold the battery. We also wanted to try making pinwheels with six wings instead of four which turned out to be much more difficult than we imagined. Although this prototype worked,...
