Additionally, the design is more resilient. Structure Go to Reference Links Concepts to Understand, continued Robust Fabrication, continued EXAMPLE 1, continued: Arm Extension, continued By using two screws, this design removes the possibility of rotation around either one of them. Two pieces must be joined together to reach the desired height. The goal is so high that a single long piece will not reach it. EXAMPLE 1: Arm Extension A robot needs to be able to reach a goal that is high off the ground. Go to Reference Links Structure Concepts to Understand, continued Robust Fabrication Fasteners The most common problem with robots that fall apart or lose pieces easily is that groups of parts are not joined securely enough and separate from each other and move around. Applying this type of knowledge is the basis of structural engineering. It is very easy to bend a piece of VEX Bar in one orientation, but it is almost impossible to bend it when it is in another orientation. Each of these structural shapes may be strong in some ways but weak in others. Structure Go to Reference Links Introduction to the Structure Subsystem, continued The VEX structural components come in a variety of shapes and sizes. One of the key features of many VEX structural parts is their “bend-able” and “cut-able” nature. These standoffs work great for mounting components in the VEX system as well as for creating structural beams of great strength. Structure Go to Reference Links Introduction to the Structure Subsystem, continued Components can also be offset from each other using 8-32 threaded standoffs these standoffs come in a variety of lengths and add great versatility to the VEX kit. These are harder to install, as you need to use an open-ended wrench to tighten them up.

Nylock nuts have a plastic insert in them which will prevent them from unscrewing.

Go to Reference Links Structure Introduction to the Structure Subsystem, continued HINT: Attach components together with multiple screws from different directions to keep structural members aligned correctly and for maximum strength! When using screws to attach things together, there are three types of nuts which can be used. This allows for good placement of components with key alignment requirements. For example, when mounting a VEX Bearing Flat there are small tabs which will stick through the square hole and hold it perfectly in alignment. These pieces will “snap” in place into these square holes.

Structure Go to Reference Links Introduction to the Structure Subsystem, continued VEX square holes are also used as “alignment features” on some components. These pieces connect together to form the “skeleton” or frame of the robot.

This subsystem consists of all the main structural components in the VEX Design System including all the metal components and hardware pieces. These parts are the “skeleton” of the robot to which all other parts are attached.
