Overview:
Small whizzing robots have been popular projects for years when it comes to Arduino at school or in education in general. They can be used to identify simple relationships between program functions and the resulting motion sequences. The robots can be clearly automated with just a few additional modules and sensors. With an ultrasonic distance sensor, the small Düvelbot can detect obstacles and react by moving around them. Line-tracking sensors make it possible for the robot to move along a line.
The Düvelbot was created in collaboration with Marco Düvelmeyer, who developed the so-called learning map for a STEM teaching unit with his technology blog"Technikwerkstatt4.0". This teaches in six steps how to create your own robot (CAD/3D printing, programming & assembly).
There are already a lot of robots and chassis. What is different about the Düvelbot?
The Düvelbot is available as a complete learning set. You don't have to buy anything else to get the robot working. The components have been deliberately selected so that programming can be done visually using the original Arduino software, but also on a block basis. For example with OpenRoberta or S4A -Scratch for Arduino.
The components are also very typical and inexpensive. This means that the robot can be used sustainably in the classroom, even if something breaks. All parts can be procured cheaply or printed out yourself. You can find information on creating the robot parts using CAD & 3D printing in this YouTube playlist and in the interactive learning map.
The Düvelbot with its components is
