Mechatronics Resources

Overview

The word “Mechatronics” was created by combining the words “Mechanical” and “Electronics”. Mechatronics products are those where mechanical and electronic components are tightly integrated and optimal design requires that both mechanical and electrical be considered together.

Spec Sheets - "Real Engineers Use Spec Sheets"

Spec refers to specification, and a spec sheet is indicates the performance guaranteed by a manufacturer. In order to design reliable devices all the components should be operated within spec. Below are the spec. sheets and other resources used in the MAE 156A Mechatronics project.
