Need advice about tracks

LordGG's picture

Hi all !

I am currently working on a tracked robot (electronics is finished, starting mechanics).

The tracks I am planning to build look like that :

I will you use the "pattern" described on many projects on LMR (the one using bicylcle chain, nuts...).

Bob is born

NiteLynr's picture

 

Well, thanks to not being allowed to alter Serenit-e's looks, I have a spare set of tracks & a dual-motor gearbox to work with - seems a shame to let them go to waste.

Bob is going to be a test-bed for trying out any new circuitry I come up with, such as controller boards, sensors, displays etc.

Hi LMR,

Now that the Phoenix CNC works good enough to do some real work, I have finally started working on a new project: 

YATB - Yet Another Traked Bot - at least until I find a better name for it

I will try to document it's building saga here, before creating a robot page for it. 

So without further intro:

Phase one: Tracks

First I have done some Blender designing, I came to design something roghly as below:

NINA - The Robot

WhiteCrow's picture

Hi everyone! I'm new to LMR. I got into robotics a few years back when something hit me. "Hey! I know what I can do this summer! I'll read books on robots and learn how to build them!" So that's what I did!

Free BIG Track For BIG Robot!!

pravoka's picture

HI,

 I got this:

tabletop.jpg

This are 10 FT (3.048 m) of Rexnord Table Top Chain, They are plastic on metal chain, model D843K3-1/4.

I tink that this track can be used in a nice and big robot track, if the plastic is sliperry can cover it with anti-skid tape for more traction.

IF someone is interested on this, only have to pay for shipping to your location anywere in this beautiful world !!!

Information of this chain on:

Track design for tracked robots

I am brand new to the robot hobby with questions about track profiles.

The high sided triangular track profile of Wall-E or Johnny 5 looks really good, but seems to make inefficient use of track links.  Other than good looks, is there a good design reason for this profile?

Of the other general profiles available (parallelogram - WWI tanks), (rounded rectangle - Christie type WWII tanks), (inverted trapazoid - short base down), what are the relative merits in terms of efficient use of links vs. object climbing ability?

So you love tracks but...

.. you are not able to find the rigth size, or...

you have enough time but not enough money for them, or...

you need real though ones, or..

you just want to enjoy with new ideas, and..

you are able to build..

 

then  maybe this link will provide some ideas to make you happy ;)

I specially liked the hinges ones.

Treads?

Thomas Countz's picture

Hey guys, I have a question for you. I see many of you guys using the track and wheel set from Tamiya (http://www.sparkfun.com/commerce/product_info.php?products_id=321) that is special built to be compatible with their dual geared motors. For such a cheap price you get a very versatile tread kit that allows endless combinations of tread length and design, however, it seems what's gained in inexpense, is lost in quality.
