This kit is ideal for children that have completed the level 1 Beginner Electronics and are ready to start building and practicing on a breadboard with real electronic components
The Arduino kit has a Arduino clone which has more connecting pins than the standard Uno, and most of the commonly used components that a beginner would use to tinker and create with.
The robot is for more advanced Arduino tinkerers, ideally Level 3 Intro to Arduino should already have been completed. It includes the robot chassis and all the component that one would need to build an obstacle avoiding robot
This kit is for a relatively new Arduino Tinkerer, who would know how to load code. It is a fun toy for setting challenges on how to get through an obstacle course
