BotBrawl as in Toronto Canada? In short, yes, most of the materials have been acquired and arena building has begun. BotBrawl events will feature 30 and 150lb sumo as well as 1lb and 3lb combat. Sign up for the email list to get all the latest updates.

Time for some updates

Slim Pickens has a new wedge. It was cut by myself with an angle grinder and Mike Jeffries cleaned it up/bent the sides for me. 1/16 Titanium


Made a pretty crude 150g undercutter. The body is 1/16 lexan spinning a 3mm bar that's 4.5 inches long. It hits pretty hard but I can only go up to like half throttle before its undriveable.


See everyone at Franklin

What you describe is very close to what I was going to recommend if using off the shelf parts. Hope to see it in action in person.

Awesome.. Thanks!

You'll either need to replace the connector on the battery with one of the other ones you're looking at or find the type of connector the battery uses and use that style of connector for at least the connection between the battery and switch.

Awesome!  That hardening article will be really useful.  I'll def keep it in mind.


With the connection, now that I'm looking closer, it doesn't seem like these:

Would fit in the connections attached to my battery (attached).  Any advice here?  Thanks!  Chris

Mike, hope all's well!  I got a bunch of parts now and I'm trying to figure it out!  Ha..

If I want to buy plugs so that I can solder the 2 red and black ends to the motor and have a plug to plug in to the battery, which ones would I use?  This is the battery I have:

Something like this?

or this?

Thanks for any help!  Chris

The second one is more along the lines of what you'd want for running power around the bot. I'd suggest having connectors like that between the battery and power switch as well as between each esc and motor to make it easy to work on or replace motors/gearboxes. You'll want to replace the existing main plug on the battery with whatever type of connector you use for the bot. (On that note, you may want to use a different size connector for the Battery-to-switch portion and the esc-to-motor portion so you can't hook them up incorrectly) I also put the female connector on the battery side of the circuit in all of my bots so with connectors that have the contacts exposed on their male connectors there's less risk of a short when something's unplugged.

I'd also suggest a read through this post on my team site: http://nearchaos.net/battle-hardening-the-inside-of-your-bot/

This image from my instructable may be a handy reference as well-
