Rolling Robots Rules to Build Cool Robots
There are no instructions for building competition robots, rather we follow a set of rules. Using Design Rule Checking is an engineering practice to assure that all designs that we produce will have a high chance of being successful. It is well known and defined in the semiconductor chip industry but also applied to other design projects typically when using a common manufacturing process. Ou common manufacturing process is the use of the VEX Robotics product line. Through years of experience we have learned best practices when using the VEX Robotics product line and developed rules of building that will assure that your robots function as expected. Follow these rules while building and your robot wont fall apart on the field.
Design Rules also give us a clear way to communicate problems or errors in the design. When reviewing a design we can simply quote a design rule that we all know instead of having to make a detailed description of what is wrong. With this language of design we can all assist one another in the building process. Learn the language of the Design Rules to become fluent in the Rolling Robots Design Process.
2 Points make a line, 3 points make a plane
This is basic geometry applied to robot building
No metal moving on metal
Use plastic bearings and spacers. Wherever we have a metal part that needs to move it should be supported by a plastic part. Usually the plastic part should be made from a bearing material like Nylon or Delrin. These materials are strong and low friction. The bearings are Delrin, the spacers are nylon.
Use locking fasteners
Star Nuts, Nyloks, Lock Tite
Use the correct length screws
Excessive length of the screws wastes time and annoys the pig.
Triangles define angles
The triangle is your friend
No sharp edges
wether you use a file or go caveman style, eliminating the sharp edges keeps everybody safe. Also it is an inspection requirement.
