Skitter
This robot is a beetleweight walker. Beetleweights are 3lbs, but as most rules give a bonus for walking robots, this one weighs 6lbs. I still need to finish this project - it is code complete, but the wiring needs a lot of work.
In order to maximize weapon mass, some sacrifices were made. Many of the electrial components are outside of the body, held on by TPU nets.
Here are some videos of it in action. The first is a walking demo, the second shows how the robot will move when it needs to invert itself (if flipped upside down during a fight):
Here are some photos from its development. It was prototyped in PETG, then gradually converted to aluminum. The armor panels will be carbon fiber.
