Spinfu

Description

Spinfu is a modular plastic Vertical spinner in the 150g weight category. Its design has been inspired by the battlebot Uppercut. This means that even if the robot ends up being flipped onto it's head, due to the design of the weapon mount, it will still be mobile and be able to continue fighting. This is meant to be in the 150g plastic antweight(AUS/UK) category. From the beginning, I wanted to build a modular robot, and I have always liked the core concept of Uppercut. I went through Alex Hattori(creator of Uppercut)'s blog to get some idea about his design. This has been in the works for quite a while but I am finally coming around to building and documenting it. Since, this is my 1st attempt at building a spinner, I am not even sure how this will work. But I am really excited to finally build a spinner combat robot!

Since its been a while I have documented my project(or even done a proper project), this documentation is going to be a bit incomplete. This will just store all the files and basic info and some instructions on how one could attempt building something like this. I am planning to do an upgrade of this in the future and will be making proper project pages and guides for that and my other competitive robotics projects.

Ready and survived the competition!!!

It was a tight build schedule but I managed to finish the robot on the night before the competition. I tested the weapon and it seemed to make a good amount of sound and it convinced me of it ability to hit things. I came in for the event on Sunday and the day started with 3 rounds of round-robin qualifiers. However, I was unable to get through safety check before my first fight since I ignored the need for a clear LED. I got it ready in-time for the second fight and went up against a solid flipper. I lost that match due to being flipped side-ways. I was aware of the possibility of that happening and had a plan to do something for it but never came around to doing anything for it due to lack of time. Important thing to do for the next iteration! I went for my 3rd match and I managed to survive long-enough for my opponent to fall into the pit giving me 1 and only win for the event. My robot thankfully winning 1 match(which was kinda my goal for the event) gave me a chance to get into a mini-rumble of sorts to try qualify for the knockouts, but I ended up loosing in that, ending Spinfu's run at its 1st tournament. I did get the opportunity to get these fights and think about further improvements for the next iteration of the robot. I will be making a proper project page/proper logs for the next version along with build instructions for the revised version.
A bit of redesign and we seem to be almost there!

My previous weapon mount was too heavy causing the robot to be almost 10gs overweight(yeeesssshhhh). I spent some time to cut weight down, got some reprints done, changing the base chassis to an older versionb and now seem to have the robot exactly at 150g. I need to do some soldering and assembly work, but we should be almost there to do some test runs!
Parts are printed!

Got the robot chassis printed and cleaned today from makerspace. I tried measuring it, and it is going almost 10gs overweight. Need to make some adjustments to the design to get the weight down since I can't reduce any more on the electronics side.
