So let's talk Limblifter. Clearly my most successful robot that wasn't two RC toys stuck together. At last event it had issues.https://www.youtube.com/watch?v=dqslR8KydnA
I learned (six years ago) that 1/8" garolite was no longer acceptable for the side lifting arms. And you can see that I die in this video for a few seconds a couple of times near the end. This had been happening during long fights for quite a while, but I didn't figure out why until rebuilding for this event. I tore everything down to retighten the gearboxes which had all come loose. Then during testing I find one of my Banebots 3-9 ESCs was really, really hot. I find out that one of the motors was drawing way too much current, making the ESC go into thermal shut down. That's why my drive stopped but the lifting arm still worked in the video above. Shortly after figuring this out the motor just died completely. There are no replacements for Banebots motors, so I had to replace all the motors will the "1000 RPM" beetle motor, which as it turns out was 100% a drop-in replacement. Also to be sure the ESC wasn't at fault and for that extra degree of safety, I replace them with 10A Wasp ESCs.
I now needed to make sure that the lifting plate never breaks again. I replace the side arms with 1/8" 6061 aluminum, and get the whole thing welded together. Noticing the side arms could still bend under a large force, I stiffen them with a 1/8" garolite layer. What used to be the entire side arm is now just the stiffener. Not to get ahead of myself, but this new wedge did not break, so mission accomplished.
Limblifter vs Pinky and The Brain
This was the fight where I realize all my mixing settings are wrong. This was a fight I felt I had a really good chance of winning, as long as I could drive properly. In a complete panic because I don't want to lose this I get a few minutes to play with my radio. I manage to find a state where up is right, right is down, down is left and left is up. So if I hold my TX sideways, it drives like normal. Except "lift" is now stick right. Ugh. The plan for the fight is to ignore Pinky as much as possible since it's the lighter, non-weaponed and invertable of the two and just go after The Brain relentlessly. I was still in a bit of a panic so it's getting hazy, but I remember I could outpush The Brain, and that its weapon (a smallish drum) wasn't too much of a concern. The Brain gets pushed out eventually and I spent something like a minute bashing against Pinky. Limblifter wins judges decision. I had a few gouges in the lifting wedge and it might have been bent slightly, but nothing major. This fight might have been the 2nd biggest grace from the robot Gods next to the time that 1/2 of 3D beat Hellrazer because I forgot to reset a switch on it, paralyzing half the drive.
As an aside, if I push a fully intact The Brain out, does that count as a huge amount of damage in a judges decision? As far as actual, real damage goes I probably lose that 6-0 or whatever, but if pushing out counts as damaging 74% of the multibot then do I win damage, like 4-2?
In the pits I find the lifting motor isn't working. The final stage planetary gears are all stripped, which has never happened before. Not a problem I have lots of spares for that. I fix my radio mix too.
Limblifter vs Broadside
This was another fight I knew I could win. I forgot that Broadside is now non-invertable, but even when it could drive upside down, without its magnets it's easy fodder to push where I want. I'm not a fan of big wide wedges, preferring my wedges to come to a narrow section, and with the sharpened spring steel I use, I knew I could get under Broadside easily. Which I do, much to the surprise of Travis or some other veteran watching the fight. So Broadside goes upside down in the first three seconds. It's not moving and I see Dirk through the arena looking very depressed as he throws his hands up. It's only at that point I remember Broadside can't drive upside down, so in the interest of having some fun and showing off, I go push Broadside into a hazard before I try for a pushout/wait for a countout. I flipped him over easily, I can do it again if I have to. After a couple of hits the hazard rights Broadside and he comes back at me. He got terrifyingly close to getting me pushed out, but I think I spazflipped over him into safety. I'm getting a little worried that I've made a horrible decision, so I make sure I'm in a safe place to get the wedge lined up. I do get Broadside flipped again and signal to the judges that I'm just going to take the victory at this point. Phew!
Limblifter vs Black Adder
So Black Adder. It's a drumbot with a smaller-ish drum about 2 or 3 inches long. I more or less fought that in The Brain, right? So same plan, go in relentlessly, flip it over, push it out. Now, no one can say I didn't do that first part. There may have been a small delay after the first hit which taco'd my lifting wedge pretty bad as I realized BA had much more power than I thought it did. But back in I go. Big hit. Back in I go. I'm losing bits after every hit. The lifting wedge gets taco'd REALLY bad. Then the non-powered arm comes out. Then a wheel goes. Then another wheel. Then the whole lifting wedge gets blasted off. (It didn't break though! Yay for small victories!) I see the shaft is bent. Good thing the gearbox with the broken gears had a perfectly fine shaft I could use for the next fight! Black Adder actually shaves off a good 1/4" around the outside of one of the 2" wheels. The announcer is loving this, exclaiming how Limblifter is still driving around on two wheels. I correct him by yelling "one and a half!". At some point the entire front nose gets broken off. Good lord, Kurtis. Thank God I don't keep my battery or power switch in there anymore. I did have much of my antenna there however, so it gets torn off. Now I have connection issues. There's one point where I'm either pushing directly against the drum, or he's got me on a wall but the result is a incredibly visible shower of white UHMW particles flying off my robot. I look at Kurtis and see his "unbridled glee" face. Now the match goes down as a KO only because after about 2 minutes of abuse I get knocked against the wall in a way I can't flip or drive away from. Because I have no flipper arm. Or the majority of my wheels. But in the video (uploaded soon, right Dirk?) you'll see the drive is still going! I take pride in that. And also I know that I likely have "robot that fell apart the most" prize on f'ing lockdown. Thankfully that was the last fight of the day, so I had a good long time to fix everything. Bash the lifting wedge back into shape, find the best of my remaining 2" wheels, ignore the front nose because it's such a pain to put that back on, but by the dawn of the 2nd day, Limblifter is back, baby. Too bad I lost that fight, I really wanted to go against Utopia, which was who the winner fought.
Limblifter vs Super Shooter McGavin
SSM is an invertable undercutter. I again wasn't too worried about the spinner. I don't remember what damage I suffered in the fight. What I remember is that I do take a couple of good hits, but I was attacking SSM a lot, got a few flips in I think, and a few near pushouts. I was really sure I lost the fight, so was a little surprised to hear I lost a split
decision. Fair enough, I'll take it. Limblifter finishes tied for 5th place, and as Travis said, I proved that a good 6 year old bot can at least hang with the current gen. If I had won, I would get to fight Pinky and The Brain again (a likely win) and the Utopia. That Utopia fight just didn't want to happen, sadly.
My lifting wedge is taco'd so badly it's hard to get under people, so I have some fun somersaulting around instead of driving. I'm sure it looked cool. I know at one point Pinky drives/gets pushed square onto my wedge and I absolutely suplex the hell out of it. It'd be nice to fight 1lb robots all the time with Limblifter! As fate would have it, Black Adder and myself are the only ones left in the arena and still working. I don't get any revenge in, and lose another wheel, but Limblifter survives the rumble, which only Black Adder can also say. Since Black Adder won the tournament as well as the rumble, so I have no problem losing to a better robot.
I do win "robot that fell apart the most" and get some mini-gorilla tape and gorilla glue, which is great because I needed both of those things, and will use them.
For the future, Limblifter needs a new frame. I like the look of the Kitbot beetle brick design. I'm not going to buy it because it's too large and heavy for what I need, but I can build one just like it that's more compact. As for the wedges, I need new ones, and they need to be modular. The current one is great for other wedges. For drums I think I need like a section of a pipe to act as both a wedge and to deflect drum hits. Maybe something that's just an UHMW block for other spinners to eat without causing real damage.
