Jumping on the SPARC wagon



The Greatest of All-Time; Play'n Krazy started life out as a gift chassis from Zac ODonnell after he won the Hobbyweiht division at Franklin 2010. After that, I built it up, it managed to win 3rd place in the Beetleweight division of Franklin Institute 2011 and Bot Blast 2013. Aside from some technical issues, it is a cool machine that I have brought to basically every event since FI 2011. I have sought to replace PK sometime so I can give it a rest, but it hasn't worked out.



Terrorpin is an all-new brick with a lifting wedge. Hasn't competed yet, but I hope the lifting wedge will turn out to be a useful tool.



El Destructo was supposed to be the robot to replace Play'n Krazy. At its first outing at Franklin Institute 2012 it almost received a podium if it weren't for the fact the weapon belt came off. At that event it used the Banebots 16:1 24mm gearboxes which gave it speed and power. Unfortunately, those motors were discontinued so I tried the Kitbots 1000RPM motors but they weren't quite as powerful or speedy so it wasn't the same. It was alright, but it eventually had to be retired after the facing Robo-Rooter in the first round of Bot Blast 2013. Alex Horne managed to bend the frame and knock out a tooth on the beater bar. Since then, it was retired and seeks a rebuild. Since I lost access to the machine shop I used to make it, it has been on the shelf longer than expected.



CATAPULT is the coolest bot I have. Its shell was made by Team Whyachi and is the single strongest structure for a robot I have. It managed to attend Bot Blast 2013, but it was never able to spin-up. I am rebuilding it now and am probably going to bring it up to Motorama to tool around with and hopefully play with.



Ferocious Mark IV is the fourth robot that I built based off the antweight wedge Ferocious that competed at Motorama 2012. It went 2-2, but I wanted a weaponed bot. Its not registered for Motorama 2015, but it is going to be up there to grudge.


Spy Cam:


Sir Wedgeleroy(possibly) 12lbs. wedge FTW

I think you need to resize your pics mate.

[Koolaid64]

change the [img] to [img width=500] for each picture

[BranYoung]

Thanks Kyle. I think that should make it easier to see.

[Koolaid64]

much better. everything is looking good.

[Harry Hills]

Sweet FBS shell dude, whats it made from?

[BranYoung]

That shell is made from 4130 Chromoly steel. It is unhardened thanks to the fact that it is only in a 6lb mantisweight class and doesn't need to be incredibly strong and/or heavy.

I'd try to clean up Ferocious' top armor. Spycam looks pretty good so far though.

I would harden it if you like it  and hardening doesn't add weight

[jfoxjfox]

Does he run the risk of warping it if has it hardened?

Jim

he runs a risk of warping if its left unhardened

[BranYoung]

To Dylan: Since that picture was taken, I added a single UHMW hoop around the back and am currently cleaning up some of the internals. I'll get a better top plate along with it.

As for the shell, how would I harden it, how much would it cost, and what kind of places offer such a service? You are right, the shell would probably last linger hardened.

[Koolaid64]

as Jim was saying though the process of hardening it can cause warping. it's a tricky thing to do right. Zacs fbs feathers have always been unhardened so you will probably be fine.

Some more progress on CATAPULT.



Tightened down the shaft. While it didn't become an issue at Bot Blast or in testing, it was always a place of concern that I knew I wanted to correct. Figured some 1/4" UHMW on top should be sufficient.



Attached the weapon motor. Another piece of 1/4" UHMW will definitely be able to hold it in place. However, I feel a support on the other side to provide more stability as well as not allow the system to flex much.



That mount basically clamps that motor to the baseplate in order to keep it as low as possible. I will need to make some solid metal faces for it though so it doesn't rotate inside the mount.



The chassis as  she lies.

[BranYoung]

Thinking of positioning wheels like this to shorten that massive chassis. Any thoughts?
