8bean builds bots IRL
8bean:
Hello everyone! 4 of my friends and I got together and decided to build two bots. We had limited resources and time so neither of them came out as expected.
The first bot is Sean.
Sean is a beetleweight wedge powered by 4 22:1 silversparks by a 3c 12v lipo. It was originally supposed to have a servo lifter but due to weight constraints it had to be removed.
This caused Sean to have a lot of excess space and be way too large.
The second bot we made is named Vaughn.
Vaughn is a mantisweight thwackbot that was made at the last second with spare RC parts. Rushing this bot out was a poor decision on our part because at the event we had a full electronics malfunction and had to forfeit it from the tournament.
Sean fought in three matches. This first match was against a plastic coffee cup and would determine our standing in the tournament based off of the damage we had done to it. Needless to say our wedge could do very little against it so it basically became a game of ram the cup as many times as possible.
Unfortunately, after this match we discovered that both of our back motors had become disconnected from the gearboxes. We spent an hour and a half troubleshooting these motors but couldn't get them to reconnect correctly to the gearbox.
The second match it fought in was against a very small overhead bar spinner named WISPTEC. Prior to this battle, WISPTEC had shredded its weapon bar mount when fighting the cup. Since the bar couldn't be repaired in time, a wooden ruler became its primary weapon for this match.
Our third and final match was against the feared Rapid Unscheduled Dissasembly. Lets just say that we came out of this match much better than expected.
Since Vaughn forfeit its match, the very generous host of this tournament provided us with an RC car toy named Sacraficial Lamb. It fought valiantly against the destructive American Banshee.
This event was a great experience and was very fun to participate in. We are certain that we will come back next year with something much more planned out and will hopefully take home a trophy.

Somebody:
Looking good! I would say more bolts will probably be needed as you guys progress onwards.

Hey chads I'm back with an all new bot (and this one actually has a real weapon)
Introducing H5N1 from Team Plague! A beetleweight vert that we just competed with at NRC.
NRC was a 3 day event that was a blast to participate in and spectate. No combat matches were scheduled on day 1 so we got to walk around the pits and talk with builders from all over. One of the combat teams stationed next to our table was having several driving issues so we helped them out and got it up and running again before inspection. Several other robotics competitions were running here as well that were fantastic to watch. One of which that was scheduled day 1 was the extremely competitive bot hockey and was fun to watch.
As day 2 came along, our fights began.
Round 1 was the first combat test of the weapon and needless to say we were happy with the result. After we flipped the opposing bot I planned on asking them if they would like to be flipped over so that we could keep going but they tapped out before I could say anything.
Our second fight was against the feared horizontal spinner Conquistador. The shock of the first impact was so hard that it stripped the screws holding the bottom panel in clean off and removed 5 of the teeth off of our weapon belt. However, since we won we were guaranteed a spot into tomorrow so we started on repairing that bottom panel. After a quick Lowes run we attached a brand new bottom panel with JB plastic weld and let it cure overnight.
Day 3
The opponent we faced in this round had an extremely tough front plow but was slammed into the glass and flipped on first impact. The team replied that they did want to be flipped over, but by the time I had gotten into position to hit them on the solid front rather than the fragile polycarb back the buzzer had already been sounded.
This fight quickly turned tides after the opposing team agreed to be turned back on their wheels and got a quick charge on our back, pinning us against the wall. Thankfully we spun around and got a hard hit on the wedge sending them into the roof of the arena and onto their top.
The finals were a rough match up against an extremely talented college team. The JB weld we used to fasten a new bottom panel on ripped clean off exposing our electronics once again. This time however, after an unfortunate flip, our battery ended up outside of the bot. Fearing the destruction of our power source, we took it extremely careful to ensure the blade wouldn't be able to reach it. The horizontal blade came close to slicing into it a few times but since we had bent their bar up it was angled barely above battery. Near the end we became stranded on it and were nearly counted out. Thankfully the opposing team gave us a good shunt on the back and the fight was on again. Afterwards, they showed us the damage that they had sustained throughout the fight.
This fight was truly the pinnacle of NRC for our team and was amazing to participate in.
We had made it to the grand finals! After scrambling like mad to fix our bottom panel and any of the other damage we had sustained with duct tape, H5N1 was up against a wedge that had dominated the competition with superior driving throughout the event. This wedge wasn't just any wedge though. Remember how I said at the beginning that we helped a team get driving again and pass tech? Well that was this bot. It was insane to be fighting them in the grand finals of all places. However, it was not a peaceful reunion because we were able to rip off the top panel and flip it, spilling its electronic guts all over the floor
Overall it was a fantastic event that was extremely fun to participate in. We even came out with relatively minor damage.
We all hope to return to another event soon and can't wait to get back into the arena!

Awesome
Congrats on winning the event 8bean
Also, I like your RL team name and logo, as well as that VS itself
8bean:
Thanks. We hope to be able to bring it to HORD in June and then head off to NRC at the Ohio State Fair in August.
