(Almost) Final version of the new container loader

In the video, you see the (almost) final version of the container loader. The only thing that is missing, is the power cable carrier.

What is new in this version (apart from finishing the build)? First of all, it has been added to the ‘real’ conveyor belt (you can see the enormous length ;-). This conveyor belt moves the containers from the warehouse to the wagons.

Furthermore, an ultrasonic sensor has been added at the top of the super structure. This ultrasonic sensor detects if a container has passed under it, so it ‘knows’ that after 1 second it can set its state to ‘container delivered’. Without this sensor, the only way to ‘ensure’ if the container has been loaded, was to use a predefined time frame. A predefined time frame has two major drawbacks: you need a very long time to make sure that the container has arrived. And you can not guarantee that the container will be delivered, no matter how long you define the time frame. You can see the ultrasonic sensor detection in close up around time frame 0:45.
