Let's Make Robots!

My first robot - Ziltoid the omniscient

Navigates and avoids objects

Ok, This is my first go at it. I will post more pics and some video as well.
Yes I did name him Ziltoid based on a Devin Townsend project. This is the first incarnation of Ziltoid here, I will work on a second one, probably just modify this one with speakers and sound. Ok, I had a little fun with the 2nd video. It does not explain anything, but it was fun to play with. Enjoy!


Ok, I can go over what I used now and costs. But first, thanks to Fritsl for the inspiration

and his how to build your first robot tutorial. Could NOT have done this or want to attempt

to do this without your guidance. The above tracks and chassis are from SUPERDROID

ROBOTS for $15. The chassis is solid and the parts that came with it to put it together

were tooled very well.


The two motors are from SOLARBOTICS, 143:1 ratio , 90 degree for

$11.50. I think next time I would go with a faster ratio, but this worked for a starter bot.


Since I really did not have some of the proper tools for this kind of project, I had to go

and get some basic stuff, like a glue gun, a better soldering iron and an extra pair of

hands/alligator clip circuit board holder. So add in an extra $40 bucks or so for that stuff.


Of course the whole thing is controlled by PIXAXE-28X starter pack with USB programming

cable. This was kind of the big single cost which was a total of about $73 from SPARKFUN.

The only problem I had, was once it came, the software CD was melted and un-usable.

No problem though, just went to the PICAXE web site and got the editor and manuals for free.


Add in L293D -Dual H-Bridge Motor Driver for about $3.50 from SOLARBOTICS. I could

not find the PICAXE servo upgrade kit anywhere that did not cost me an arm and a leg for

shipping, so I just used the 330 ohm resistor and had to do some searching for header

pins to hook up the servo and IR sensor. Found some 1X10 header pin connectors at

IEC for about $0.31 for 10. Problem here is that I bought like 10 sets for about $3.10

and paid over $9.00 for shipping. Lesson learned? Yea, buy whatever you can at the same

site at the same time and save on shipping. Used a Hitec HS-322HD servo from ROBOTICS



I used the Sharp GP2D120 IR sensor with the IR sensor cable from ROBOTICS CONNECTION.

Cost for those was $9 for the sensor and $3 for the cable.

Other than the basic design change with tracks instead of wheels, the only other change

made was I added some header pins to the A/B motor outputs and connectors to the wires

from the motors so I could easily add/remove the motors and or board to another project

If I needed to. This was an awesome first time experience and thanks again to Fritsl and

everybody here for there input and knowledge. Hopefully this will help some other beginner

start on his, or her's robot. Now on to Ziltoid II.....INDEED HUMANS!!!!

I saw it!!! Very fast!!! Turbobot! :)

Hey, you have good taste in music :) (Devin once signed my brother's boobs).

Nice to see video of that Tamiya tracked kit too. I've got one here waiting to assemble, and I was curious what it looks like in action.


Thanks, Devin is one weird guy, but his music is amazing! I would absolutely get the tracks again. Faster motors are a must though.  It is a solid kit and was pretty easy to put together and so far the tracks have held up very well. Good luck with the tracks HUMAN... I'm off to find some coffee :)

nice updates, its always good when you do things thinking in future updates, that will make your robot more portable and more usefull in future.

Nice robot, i'm sure that will help everyone that see it.

 Good luck for  Ziltoid II

As i can saw in the movie motors are really with power problems, you shueld think in add a external power to motors, or a 4rd AA baterry to the pack, if you get something small to climb or something heavy, the low power will mean low torque, and the motors will not able to keep going as you want to.

Good luck with the project.

Yep, I agree.  That will be the next major inhancement for Ziltoid II. Still trying to get a feel for how to wire that properly, any help/suggestions would greatly be appreciated.

i wrote an answer in the forum.. Also - have you read the official documedntation for the board?

/ Fritsl

Thanks!!!! I think I have a better feel for what needs to be done!! Power is next on my project list including rechargeable batteries.  I thought first I would give a go at programming for the chair challenge first.

sory, but i can't help you with that.. i never used picaxe, my experience with it is zero. =S

there are already some topics about that in LMR, try search for it.
