Aluminum Channel - 12"

These aluminum channels are the building blocks to the Actobotics line and function as the back bone to your electromechanical project. These channels can serve as connection points for servos, motors, and shafts while still providing an easy to assemble structure. Each aluminum channel has exterior dimensions of 1.5" wide by 1.5" tall, interior dimensions of 1.32" wide by 1.41" deep, a 0.09" thick wall, utilize both the 1.5" and 0.77" hub patterns, and are 12" long.

Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.

  • Exterior Dimensions - 1.5" Wide x 1.5" Tall
  • Interior Dimensions - 1.32" Wide x 1.41" Deep

  • Backbone is one word, not two... :)

  • sparkfun, what is going on with this item? Is it discontinued ? It has been out of stock for 2-3 months now? Please can you at least update the status with a valid arrival date?

  • This 12" channel and the 6" one are the base for building any actobotics. The items have been out of stock for more than a month now. I also check the servocity.com, the same thing, they said that they are going to be back in stock in a couple of weeks. I had to drop my project because I don't really have so much time to waste. Also, sometimes the channels have the hole pattern off so I had a very hard time to screw the different hubs in. As a building system I give it 5 stars, for quality 3 stars. Overall rating 2 stars because extremely annoying "out-of-stock" issues (I had to practically halt my project completely).

  • Tetrix looks like a substandard twin of this product designed for Lego lovers and children.

  • looks alot like tetrix
