Introduction: Paradox the Ultimate Lego Battlebot

Picture of Paradox the Ultimate Lego Battlebot

THis is my battlebot named Paradox. He has faced many other lego battlebots and defeated them all.
I have made a whole series of videos for this robot.

Below is the link to his playlist of all his videos.

Do you know the gear ratio?

GATEBOYNXT (author)Mr Tesla2014-03-03

Fortunately I found the drivetrain sitting around for some reason:
It is in the following arrangement (numbers indicate teeth count, P indicates powered, W indicates wheel attached, all are the double bevel gears(forgot what they were called))

Or in ratios with base 12:

It was mainly designed that way to have a large base and surface area. At the time, my robots trended towards lower to the ground, compact, and not very tall.

Nobody commenting, but this is pretty awesome! Reminds me of Robot Wars :P

GATEBOYNXT (author)Lowney2011-06-28

Thanks for commenting and the reply.
I plan on joining a robot battle comp. later in life.

i gotta admit it is eye catching...but so expensive...but worth it......but i don't have the money.....

or you could get a used one on Ebay.

It doesn't have to be too expensive. Just be smart, unlike me, when it comes to buying pieces. bricklink can let you buy tons of pieces for a really low price.

Wow all I made was a 3 1/2 pound horizontal spinner and it only has 2 motors. It is a play off a BattleBot called Tombstone. The spinner can destroy practically any pieces. Its weakness is the small thin flats. The spinner is 1 3/4 in off the ground and it is remote controlled. You want to fight when you rebuild it?

Perhaps I'm missing something...

Where is the "instructable" part of this?

Mr Tesla (author)2014-04-18

Just out of curiosity did you program it with nxt-g or robotC ?

My friends and I are doing battle bots. When I was looking for bots, I found paradox and immediately knew it would be amazing to bring in. Any chance I could get the instructions? Thanks!

GATEBOYNXT (author)crazy99red2014-03-03

I'm sorry, Paradox got dismantled for other projects. The best way to rebuild it would to reverse engineer it from the videos.

Drive train closeup just for kicks.

How is the drivetrain geared?

GATEBOYNXT (author)Mr Tesla2014-03-03

It uses a whole line of gears. It's currently dismantled but here is a glimpse from a video screenshot:

Was Paradox autonomous or RC controlled?

GATEBOYNXT (author)jmiester2011-08-24

He was Rc controlled. Though i could make him automotous.

jmiester (author)GATEBOYNXT2011-08-24

How did you RC him? And what technic set did you use?

GATEBOYNXT (author)jmiester2011-08-25

i used Lego mindstorms NXT so i controlled him with a laptop which connected viaa bluetooth. Besides the 2 NXT sets used to make him, i used the motorized crane motorized hauler and buggy.

crazy99red (author)GATEBOYNXT2014-02-27

How did you control it with your laptop? I know there is a "play selected blocks button" but don't know how to specifically do all of it.

jmiester (author)GATEBOYNXT2011-08-24

O, cause I'm trying to make a Paradox-like battle bot, but I don't know how to RC him...

jmiester (author)jmiester2011-08-25

I have now made... Singularity, battlebot 3084

GATEBOYNXT (author)jmiester2011-08-26

AWESOME! What is he like? You can compare him to Paradox through his pictures and his videos.

jmiester (author)GATEBOYNXT2011-08-26

I made an i'ble (sort of) for him. Check it out! He's only half the weight of Paradox thought, since I used only NXT parts...

GATEBOYNXT (author)jmiester2011-08-27

I sure will! Thanx for subbing!

paradox has only three motors.

jmiester (author)GATEBOYNXT2011-08-28

So does Singularity! :) where r u if your close we could pit them against one another

GATEBOYNXT (author)jmiester2011-08-28

Bay area

jmiester (author)GATEBOYNXT2012-08-17

San Francisco?

jmiester (author)GATEBOYNXT2011-08-28

O, im in NJ

SwaggerFul Swellow (author)2013-06-27

Please post instructions! Pleeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeease!

KerelMC (author)2012-11-26

D: i can't download the pdf unless i have a pro membership

jmiester (author)2011-11-22

One thing I have learned from these videos is... treads = MAJORLY BAD IDEA!!!!!

P.S. Singularity Mk II will be instrucablized soon, but the pictures may be cr**py since I have to use my webcam (my camera is out of bats, and my family goes through double-As VERY quickly), but sorry for the loooooooong wait :0

theswordninja561 (author)2011-10-08

let me just..........visit real quick

pkothari2 (author)2011-07-26

may i get to know the materials reqiured to build this battlebot and how is it is made.

i am a science student and i am very eager to make this battlebot and give your name in my school's science fair.

please help me as soon as possible.

waiting for your reply,
thank you.

GATEBOYNXT (author)pkothari22011-07-26

it used pieces from the technic hauler,motorized crane, nxt 2.0, and nxt 1.0
Paradox has two long gear-trains that powers the 6 wheels. 2-36 teeth gears, lots of 20 tooth gears and lots of 12 tooth gears.

It took me three to five hours to make paradox. Planning? I did not plan before him. I just built him and thought about it along the building process.

i am also a science student. You can call me by my youtube name: GATEBOYNXT

Thank You,
