Hi Folks, This is my experimentation with cheap chasis and tracked wheel set which i found online. The whole set up cost me between $50 - $60. This is my infial … Read more

Aluminum Frame

I am trying to build an aluminum frame for my robot but I am having trouble finding good techniques to cut and bend it. Anyone know a good way to cut and bend aluminum for a frame? I have basic tools, but not anything fancy. The frame needs to be about 7.5 inches and relatively sturdy.

hacked chassis' moves too fast or not at all

So I built three little bots so far. 

One with a raspberry-pi, (6V motors):  

One with an arduino (12V motors):  

And another with an arduino but a hacked remote car (7ish, volt motors):  

Robot chassis

Hello everyone! Now i finished my robots chassis and i want to show it to you.

First picture is front of it:

And secon is from left side:

And these are wheels i may use on it:

And parts are taped with two-sided tape.

Best robot chassis

Was wondering what you guys thought the best "chassis" for robot development was.  Not looking for electronics or a "kit" but just a platform with wheels (or legs or whatever).  I like the idea of doing my own electronics (processors, sensors, power systems, etc.) and could/would eventually build my own from component parts, but I like the speed of starting with known motor/wheels/platform that are well matched and robust.  I have already fried a servo trying to start with that.  I also figure that by the time I bought motors, plexiglass, wheels, etc.

SSS - Servo Suspension System

This is my first experiment with the MakerBot. I am totally thrilled with this machine!!!

SSS (servo suspension system) is designed to support standard servo motors and act as a basic suspension. It is still a work in progress and has not been tested yet.

Will update results as soon as possible (still waiting to have my lab back).

I would like to know everyone's opinion on this  :)


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.

Tread Chassis Design Question

Alright, so I am new to robotics as well as this site, but here is a question I feel I have to ask.  I need to ask because it will effect a future project I want to do when I am more experienced in Robotics.


Alright, so the theory behind this question has entirely to do with ground clearance with a treaded chassis.  I notice that every bot with treads has very little ground clearance, and was wondering if there wasn't another way to do the chassis so you could increase the clearance and what kind of effect it would have on terrain options.
