We are all exposed to robotic systems everyday. It is important for students to understand how these systems work and how they can create their own.
Edison Robots, at junior level, are great for teaching directional concepts and sequencing of instructions. Using www.edblocksapp.com introduces them to the concept of graphic based programming. As students gain confidence, they can progress to www.edscratchapp.com.
Using Lego and other add-ons, it is possible for students to use the robotics to prototype robotic systems such as the ideas listed below.
