Wire Tubing

The part was created by Issac Magallanes, from the team 6526E of La Verne, California.  The part was a type of tubing in which it can be attached and tightly fastened to the c-channel so that the wires can move freely throughout the tubing and still be organized and have the connections available to switch.  The functionality of this part was improved upon the ideal situation to give free wires the slack to move along the robot but not be in the way of moving parts and gears.  This tubing would very efficiently improve wiring for many teams with limited resources, such as zip-ties and rubber bands.  The new part would attach to c-channels, not taking up too much space, so that the c-channels can still move about their normal rotational limits. I first brainstormed what part I could make using the scientific method and with the help of elimination, I was able to narrow down the idea that would be most functionally successful in terms of the use and organization of wires in the VEX Robotics EDR design of competition robots.  The many whiteboards I had were helpful in expelling all the ideas flowing from my head like a river flowing after opening a dam.  The number of ideas that came from my mind was extraordinary considering how simple this piece was. The software used to create this masterpiece was none other the magnificent 2016 version of Autodesk Inventor.  I have much experience with Autodesk Inventor due to the engineering classes and courses provided by Damien High School.  This four-year program includes an Introduction to Engineering Design in which we, the students, are instructed to learn and practice skills of using Autodesk Inventor, such as creating custom parts, and the reverse-engineering of common daily-used items.  Since I have had lots of practice with Autodesk Inventor in the afterschool program of robotics, and the engineering courses, I saw it only fitting that I used Autodesk Inventor to create this part.  I also used the CAD VEX parts library of 2016 to model the tubing holes much like the screw holes of the VEX battery clip.  The exact measurements of the part, measured using a caliper, were taken using parts from the VEX parts library and real-life parts used on many of the robots from the teams here at Damien High School.  The part was made so that you can add more tubing next to each other to create longer lengths of tubing for longer c-channels and farther moving parts.  This part had many versions made to make this part working and was difficult in some areas but was fairly easy to make.
