The Problem.

The German company Kärcher needed a new and fresh idea for their existing robot vacuum cleaner. The competition with the cheaper brands was getting harder and harder and to keep up with the modern customers Kärcher thought it was time for something different. The focus of this project was again on coming up with a realistic result. This result would be presented in front of the whole group of students and a delegation of Kärcher by means of a small video of 1 minute. (see the video above)

The Process.

After a presentation of Kärcher about the problem we individually started brainstorming for some good ideas and solutions. Kärcher gave us some of their standard robot cleaner parts as SolidWorks files. We had to build the vacuum cleaner around these basic parts (engine, nozzle, pump). Almost any student created a variant of the existing vacuum cleaner, a circle that could rotate on collision. I started with a different idea, a tube with only 2 wheels which drastically improves the maneuverability.

The Result.

I chose to go on with the tube concept because of it’s innovative nature and potential. The tube can be opened in the middle to take out the dust. The body of the tube is an obliquely cut, extrusion part that is connected to the other half by 2 injection molded parts. The extrusion profile gives the concept a huge advantage at the assembly of the robot. All the parts can easily slide in this extrusion profile (see video). Kärcher reacted surprised at my solution and specifically asked for my solution at the end of the presentations.
