Abstract: An all-in-one symmetrical mobile modular mechanical and electrical lab that may be used to explore, expose, educate and provide basic hands on training in core technical skills. The modular lab is constructed using more than seven different types of materials and a variety of fasteners to enhance the learning experience. The modular lab consists of a middle section and end sections connected by hinges. The modular lab has a design consisting of removable and interchangeable panels. Individual components are interchangeable and may be easily removed, replaced or customized. In one specialized embodiment, the modular lab may be used to simulate the mechanical operation of a typical air conditioning system. The modular lab folds in to ease transporting and is mounted on wheels which makes it easy to move. Never before has a compact mobile lab existed that allows as many as twelve (12) individuals to utilize at any given time.
