Fractal - Beetleweight combat robot
@ December 30, 2011
Robot sumo/Combat
Cost to build:
$350
Time to build:
40 hours
Weight:
1200 grams
- Actuators / output devices: Modified Hitec Servo
- Control method: remote control, RC
- Power source: 14.8V Li-Po
This robot built between 2010-11 is designed to compete in the 3lb combat robot weight-class.
It is very fast and agile, and can climb over objects using both it's tracks and the arm which can rotate 360degrees around its body.
Here's a labelled diagram of the robot:
Here's an image of the first build (circa December 2010) with 11.1v Li-Po and cheap (eBay) 15kg-cm torque modified servo
And finally an image with the top cover (carbon fibre) on:

For some reason I thought this was
bigger. But I guess there's nothing else in the pics or video to compare scale. I only realised this when I looked up os bots for the treads. They say they are only 5 inches long. Nice bot, have you thought of putting a turret on it and making it autonomous?

Quite strangely the only picture I've got on this computer with a scaling object is with a gutted cordless drill.. of course this is only useful if you know how big they are:
Making it autonomous is certainly on my to-do list (my only other experience with autonomous machines has been the 'Cybot' of the 'Real Robots' magazine many years ago) but it will have to wait a little while for other projects and university!

Congratulations!
You have made a very good robot. It looks very nice and it seems that it´s easy to control (or you are very good with the joystick :))
Good luck in the competition.

Please post more than a photo. Aside from video it would be nice to show some photos of the robot during construction / repair so we can see your workmanship.
More information about what parts you used and why / how you chose them would also be helpful to the beginners on this site.

I've attempted to post additional pictures but can't seem to find a method other than through 'attachments' - should I be adding pictures embedded in comments? Thanks!

You don't see very many combat robots on LMR.
I like it. It looks real beefy!
It would be cool to see it destroying something!

Here's a very old video http://www.youtube.com/watch?v=Zi_tZdKFg3A&feature=player_embedded this was back when it was at 11.1V and with a very cheap servo, it now performs much better so I ought to do another video soon
