PostSubject: Camden's confoundations   Wed Apr 13, 2011 6:14 pm

ok, as suggested, I started a new forum for myself. Along with that design, i originally came up with the idea after seeing wayachi, and on a 120 lb class bot, a friend at school, his dad has a battlebot that they named tutrle w'axe, which looks similar to wayachi, but has two arms instead of three, and got massacred by shrederator. I never saw that match, but it was about 4 years ago, they haven't done anything with it since, and i just found out about it. It is horribly bent up, and i don't have any experience with acetylene torches, just a soddering iron.

I was at this event at the state fair 4 years ago. this is where my liking to full-body-spinning robots really started, its also the exact robot that crushed the aforementioned turtle w'axe (sorry i can't find ANYTHING on it ;( but when i get a chance and a camera i'll take a pic of it sitting in my school's shop.)

this is just a quick freehand sketch, i have about 30 more pics, but this one is the most full, the motor dimensions may be wrong, but if anyone knows where i could get some stuff for getting this thing from a sketch, that would be really helpful Wink

Kindof hard to see the details of the picture.
What weight class are you planning to be in?
What components are you planning on using so far?

Im planning on doing the 450g weight class, the drive motors are those 30:1 gold motors, no idea where to get the ESC or transmitter/reciever, nor what to build the weapon out of (full body spinner), here is another pic:



2 motors you say? will it still be balance-able when gyro effects kick in at hopefully 5k+ rpm?

really sorry for the not-so-good pics...i don't have a good camera

I'm not sure if I'm confused as what your describing (I mean you are using metric lol) or if your confused about the way the FBS works.
Take a looks at kyle's 3lb FBS he is building:
http://battlebots.forumotion.com/t633-donatello-beetleweight

This is probably the most effecient way to lay out an FBS. With an ant weight you can probably get away with direct driving the shell with an outrunner motor.
Take a look at fingertech robotics website. They make great antweight parts (drive motors/ESC)

I tried my hand at making an ant fbs... epic fail. You could probably use Sanyo gearmotors as they are much lighter than the Spark Gold gearmotors (.3 oz compared to 1 oz)

Take a look at this fbs:

http://www.youtube.com/watch?v=dUYGQR9fLMU

In the description there are also some photos.

To warn you, it is very hard to make a successful ant fbs... The shell needs to be very balanced

Another example of an fbs is Baby Blaster, bent my titanium on Warpig pretty badly:

as is my design isn't that space efficient if i rework it i could probable get a smaller shell

no one said you had to direct drive it although most ants do.
Not sure where your going with the motor alternatves you posted when the ones kyle posted are tried and proven.

and at this rate, considering the price of the motors, i would be willing to try direct drive. It would end up being less weight that i could add to the weapon. Very Happy

also, does anyone know of any type of design software i could get, especially for free? otherwise i'm stuck with notebook sketches or MS paint

google sketchup is free
the motors i recommened would be for you weapon system, and you would gear them down with belts and pullies
