How To Make A Winning Knex Battle Bot

How To Make A Winning Knex Battle Bot
I have been in a number of knex battle bot competitions. Each time I learn a few new things about making a winning battle bot. I'll summarize the basics and show you how to make a piece efficient battle bot.

The main thing to remember when you are planning is that you will be supplied with a limited amount of parts. So think basic! The person who tries to be fancy always looses. Many times I've seen cars that don't even have steering come in the top three. The people that win almost always have these five things:

Requirements:
Low center of gravity
Low to the ground
Weight over the wheels
Steering
Flat front

I'll show you how I achieved these things in a battle bot I made that won first place, and I'll give you some tips along the way.
I hope this guide will help future battle bot builders!

Step 1Creative Planning

Creative Planning

Your planning time can be some of the most valuable time you have, and depending on the contest you might have very little. You do not want to waste it!

Think simple! You will be given a variety of parts and you probably wont want most of them. I know that a lot of times they give you a bad selection of parts to make you think and be creative, but never forget the fundamentals!  Don't waste time and parts on fancy spinning things and lifts to flip the opposing car. I made this mistake my first time to compete and I had to spend half of the time I got to battle rebuilding my car. Just don't do it!

I have a tip: Maybe include the rules of knex battle bots in here. I don't even know anything about battle bots.

Basically, there is a ring or square, and two robots need to push each other out of the ring. I've only ever seen one knex bot, and it was awesome (the Mindstorms bots ones epic fail, don't ever make one). I used a bot once that just went forward really really fast, and I won several rounds.

Yes i used Mindstorms to make all of the robots. Some have power-functions to power it up! The one below is called paradox. It has a whole playlist on my channel.

i once made an awesome knex battle bot. wasn't a member of ibles at the time so i couldn't post it. i unfortunately scrapped it for parts:(

Nice! This is the first time I found out about battle bots. Just a quick question I don't get how you steer does the robot do it automaticly or does a person have to manualy switch on and off the motors. Great ible otherwise!
