Team Tiki - Web Store - Botbitz Escs - drill motor- hubs, mounts, wheels

[TeamTiki]

Hello,  My name is Chewy, i'm captain of Team Tiki Combat robotics.   I have been interested in the sport of combat robots since 1996 and have been competing since 2000. 

This obsession has driven me to gain an education in manufacturing and start a small machine shop, tailored to bot people and parts.

My poorly made webstore is located at:

http://ttrobotics.com/paypal-webstore/

I am a state-side reseller of BotBitz  Escs, and try to maintain a small stock of 10,30, and 85Amp escs.  Altho these come at a small price premium to ordering direct, They can usually be delivered in 2-3 days Via priority mail.

I am also trying to develop a line of "budget bot builder" parts. The first lines of products are based around cordless drill motors, featuring mounts, hubs and wheels.  Please see the tips section for a step by step tutorial on how these inexpensive drills can be converted to powerful and light weight drive motors, suitable for 12-60lb combat robots. 

I am also available for custom or semi-custom work. I'm still learning the trade, and prices reflect that, sometimes so do the parts...

thanks,
Chewy

Hi Chewy, I'm gathering parts for my first combat robot. It's a project for my kids and I. I've harvested several 18v drill motors. Are these typically brushed motors? I assume they are but please confirm. Would the botbitz 30A ESC handle these motors? Or is the 85A ESC needed? Also, your website says these botbitz ESC's are based on brushless Turnigy ESC's. Are they hacked as brushed ESC's?
Thanks for your help!

Welcome to robot building!

What weight class of robot and type of robot are you hoping to build with the drill motors? The drill motors are brushed (except for a few very high end drills that use brushless). I use these motors, if you wait for coupons, you can get them for $15 each (http://www.harborfreight.com/18-volt-38-in-cordless-drilldriver-with-keyless-chuck-21-clutch-settings-68239.html)

I have used 2 of the cordless drill motors in a 12 pound robot that had a weapon running on a Scorpion XL which only handles 12.5A continuous, 30A peak. I think for a 12 pound pushing robot, more current might be needed than what I had. I don't know if the Botbitz ESC rating is continuous or peak, Chewy can probably help with that, but a 30A continuous rating would probably be okay for that weight.

Ordered some controllers on Saturday, they came today. Thanks Chewy!

Most inexpensive cordless drills are still running brushed motors.  I have used a pair of 30A Escs, driving 2 pair (4 motors) of drill motors on a 12lb testbed.  ( 12v drills  running  a single pack of 18v nicads)  This combo worked in testing and didn't get alarmingly hot.  If I was running a 4 wheel pushybot with a heavy handed driver I would upgrade to the 85A escs.  But if its just a weapons platform a pair of the 30A would be fine.

hey chewy what kind of drills do you recommend for taking apart for the motors and stuff that would be used with 30 amp esc. And how much would shipping up to Canada be?

Just ordered 2 10amp ESCs.
