As promised, here is the presentation of the best and latest of project SASHA Vex, in blog entry format.
The first design is seen here.
However, pressing the trigger and watching about 10 Lego pieces fly across the room wasn't quite enough. At Project SASHA, we strive to improve the robots we use constantly, and this was our goal from the beginning. Although no official documentation was created at that time, we extended the clip (the straight up piece seen in the image that feeds the ammunition) so that we could shoot for a little bit longer. We also created a set of wheels so that SASHA could drive around, and an automatic firing mode. Finally, to top it all off, we added a rolling clip that would say "Shoot!" every time we shot a round. This was mainly for amusement purposes, but it also put on display some of our early programming capabilities.
SASHA 3.0 was designed for the purpose of wireless streaming. We wanted it to be very fast and extremely versatile, while having streaming capabilities that allowed it to hold a camera in a safe way and travel long distances while maintaining reception (for the remote and for the camera).
Recently, we started building a miniature robot named SASHA 4.1, paying respect to all of our robots who have contributed to the design of this new machine. This robot's project goal is to sweep mines, as seen in the Vex mine sweeping challenge.
