You can't really tell from the picture but every spot there was a screw hole broke... all the motors are free floating... It was literly being held together by the duct tape. I don't have another competition till next year so I have some time to design my next robot. I am going to rebuild this one with a metal frame and replace the spinning blade with a lifting fork ala panic attack. Then I am going to build a super low profile melty robot designed to destroy the robot that broke mine.

Its a little fat but this is the design I am working on right now. it is made out of 6" square aluminum tubing 0.187" wall thickness and 0.8" height

Reminds me of Massive

<bovril> it collects data about the surrounding environment, then discards it and drives into walls

just found a competition and its in a month.... AHHHHHHHH speedbuild!

Strangely familiar

How did your design work out?

Mixed results. It was pioneering some of the original Rich Olsen melty brain code, which worked for the most part, however due to a last minute testing accident, I destroyed the accelerometer. So it competed with a manual "guess the rpm with throttle position as you go" setup which was fine in testing but completely impossible to do in combat

A series of platform issues (wheel wear, base friction, high battery and motor consumption) lead to sub par results afterwards and I eventually got bored of fiddling with the melty

I am also using the same melty code but I am in the process of modifying it.

I am changing the calibration routine to have its own dedicated switch
and I am going to try and use a car esc (hopefully it has fast enough pwm)
so that I can spin either direction and more importantly get out of corners.

Also the USA scarlet clone is going to be at the event I am going to. If you want I can try to get some good pics of it...

Started milling... gonna take awhile...

1lb robot I am working on. built it in a week
it has a .06" stainless wedge
and a shell with .25" aluminum armor.
all thats left to do is paint, new wheels, and a hole for a led and cutoff switch.

The wedge is shock mounted so that it will retract on impact.

It still needs a name any ideas?

Boing.

I kinda decided on Recoil

So its been awhile since I posted here. Recoil has now competed in 3 competitions and continues to place in last. Its kinda fun to drive so I don't have the heart to retire it. Death by 1001 cuts has taken 1st place and 3rd place in two different events and my 3lb melty tempest took 2nd at one event but due to various problems I am retiring that robot. I may in the future build a 1lb melty but the larger weight class just cant handle it IMHO.


from left to right is recoil (after being rebuilt) tempest and Death by 1001 cuts

I am also designing a 150g robot.


On another note what type of O-Rings do you guys use?

I am using A70 Silicone (red orange color) and they keep breaking on me under stress and Id like something with a tad bit more stretch.

I used 5mm green round PUR string. Weld it yourself stuff.
