It is a while since we last spoke… Since milestone four was this week on Tuesday we had our hand full to try to make the prototype work. At the end it worked partially.
The interaction between mechanical and electronical parts is still not optimal. Furthermore, there emerged a mystery when it comes to the money counting system. When inserting the money, the piece is sliding down a ramp. This process works excellent. At some moments however, the piece does not even slide a millimeter down the ramp.
Our mechanical engineers looked at multiple reasons: impact of heat on the plastic, surface friction, etc. Up to know there is no solution within the range of vision. Nevertheless, we are still positive to find a solution and highly motivated to start our trip to China.
The next blog post will probably be in China. With this in mind, we wish you all the best and speak to you soon.
