Patrick's Antweights

Hey guys,

A bit of a journey into the past before we get into what I’ve been working on recently as I found some old videos of my first ants from 2018

1000009396

My first real robot, it never got a name and got very little development before the next one, but it’s fun to look back.

Full size receiver, dual 10a red Chinesium ESC’s and some basic N20’s

After the success of pushing butter around, I’d seen a video of witch doctor, and I thought it was really interesting how the design elements were not only decorative but also functional, which led to this

Scorp, my first spinner robot and my first (and only) ant hammer saw to date. I’d really like to resurrect this soon, as I loved the look of it compared to a solid block with some weapons on it. It later got an axe conversion and then was gutted for parts earlier this year.

Sometime before this I made the firestorm model that was available with continuous rotation servos, which led to my trying to design a flipper. I have no real photos of this working, but the geometry was terrible for both flipping and driving as I’d tried to stuff a 37g servo into an already crowded chassis.

That’s all that I can find looking back, based on my photos I didn’t make any other ants between 2018 and 2023 which seems odd, but changing jobs and moving will do that I guess.

Great design history :grin:

The in-between times

I do a lot of STEM activities through work, and robots are always popular with kids and at events, which led to making some ant versions of my first featherweight, fortitude


(Hiding in the background here)

Its a great little robot, and accurately captures all of the problems the featherweight has with regards to it’s weapon while remaining old AWS (100mm³) compliant.

It’s around this time I also made “transvector”? It’s been a long time but the name seems about right. It’ll have its own post later on as it’s more of an ancestor of my current undercutter design.

Now finally having an antweight again, i started looking at local competitions for the first time in years and found SCAR, which being in Sheffield seemed pretty attractive as a first event.

I decided to enter a spinner, and with about 3 months until the competition it seemed like a reasonably achievable goal, so I ordered a large bar from monsoon and started designing

I wasn’t happy with either design, and so I kept going back and forth until it was a week before the event and I had to make something quick. “Friday Night Special” was made on a Friday evening, and was the result of desperately trying to shoehorn my new favorite paper-roller wheels into a Thagomiser-style build using a drone arm.

On the next Thursday morning I ended up with this

It didn’t drive inverted, my polycarbonate armour never showed up and it drove shockingly, so on my lunch break I designed it’s replacement, pretty heavily based on a generic ant found from thingiverse. It’s prone to wheelies but a lot of fun to drive on 3S.


Lunch break ended up competing at SCAR under Friday night specials name, and went 1-3 which earned me the best newcomer trophy, which I was over the moon with!

Taking what I learned from lunch break, I decided to make a simple test bot to run as a reserve and let people drive if I manage to convince someone to come to an event.
I struggled with a a theme for a bit, and then found a mini RC forklift beacon which settled it for me.

Called PowerLoaner, it’s inspired by the loader from aliens, with some details from its design incorporated as features to aid In pushing. It uses the same double-wall construction as lunch break for a sacrificial front to defeat spinners. This was essential I felt after my performance at SCAR, but after printing a TPU version about a month later it feels a bit pointless now. The PLA versions also put a lot more shock into the motors, which if you run them for a long time has a habit of causing axle wobble and then premature death.
The TPU version also is far better at getting under opponents due to its compliant front end.
If anyone was at FightFest last year I had some of these running in the breaks for spectators to enjoy.
