Motors and Tracks

For my next project, I want to use actual motors (I have used continous servos to this point). I also want to have tracks instead of wheels for this project. My question is whether or not the motors I want to use will connect to the tracks I want to use. I want to use this Tamiya Track Kit seen here http://www.robotronic.co.nz/images/TAM-008-000.gif and I want to use the Solarbotics motors like seen here http://www.robotshop.us/solarbotics-gm9-gear-motor-9.html .

Avoid object via ultrasound, indicate turn-direction with two LEDs, turn on its "head lights" when it enters a dark area, (Possibly RC/autonomous in the future)

This is my first robot (actually I made one a few weeks ago that was not so good...just so I could see something moving--instead of just lighting up LEDs and such). … Read more

Modifying Parallax Ping)))

I'm wanting to make a small physical modification to a Parallax Ping))), however I'm not sure that it won't destory the component.

 What I'm wanting to do is create a backlight for the ping (such that it would look like glowing eyes). The way I imagine donig this is by drilling a small (maybe an 8th of an inch in diameter) hole in the side of each cylinder on the ping, and insert the the tip of a standard (or possibly smaller) sized LED into the hole from the outside. This should glow the inside of the cylinders fairly well, and should have a cool affect.

Beginner here. I need some direction...

I have come to a point in my life where I have some free time for a new hobby and I think robotics is something I could enjoy.

As I understand it, the following seems to be the basic skillset necessary to really get into robotics:

-  ability to understand and create mechanical features with your hands

-  have an understanding of electrical circuitry (especially in the context of commonly used robotics components)

-  have an understanding of event driven computer programming
