Building with VEX Robot Design Every robot is designed with a purpose in mind – What will the robot do? Determining this is sometimes the most difficult step. Tasks can range from very easy to very difficult, and some may require quite complex robots. Some robots will be capable of completing multiple tasks. After determining what the robot will do, the next step is to decide how the robot will accomplish the task. It is tempting to start building immediately, but often a little bit of planning and design will result in a much better robot. Creativity and innovation will be important during this part of the design process. Some engineers and designers have trouble thinking of how to accomplish their challenge. In this situation one of the best things to do is to search for outside inspiration. Inspiration can come from anywhere, so good designers are always looking for ideas. Examples of designs from the “real world” can sometimes be adapted successfully into a VEX robot design. There is no shame in improving an existing design or refining a previously used mechanism. Two brains are better than one, and bouncing ideas off of another designer will often help stimulate creativity. Good designers will collaborate with others to improve their designs. Design is an Iterative Process The most important thing to remember about building a VEX robot is that it is an iterative process. Most designers will find themselves building and rebuilding things over and over again until they get the robot functioning well. The VEX Robotics Design System is well suited for this iteration. It is easy to take things apart and modify assemblies without any major fabrication of parts. This allows users to build VEX systems quickly, while a less versatile kit might take much longer. When building robots, a designer should never be afraid to modify work if this process makes the overall product better. Designers are always thinking of ways to improve their design. Introduction to the Structure Subsystem The parts in the VEX Structure Subsystem form the base of every robot. These parts are the “skeleton” of the robot to which all other parts are attached. This subsystem consists of the main structural components in the VEX Design System, including all metal components and hardware pieces. These pieces connect together to form the “skeleton” or frame of the robot. In the VEX Robotics Design System, the majority of the components in the Structure Subsystem are made from bent sheet metal. © 2011 Project Lead The Way, Inc. GTT-AR VEX Building with VEX – Page 1

These pieces (either aluminum or steel) come in a variety of shapes and sizes and are suited to different functions on a robot. Different types of parts are designed for different applications.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
