My submission for the crane contest: the candy crane. The candy crane has been inspired on a harbor container crane. The name points to its functionality: picking up candy and drop it in a wagon (it is part of a fully automated train layout, see siouxnetontrack.wordpress.com).

The crane uses 5x EV3 M motors:

  • 2 motors to move the body (X-movement)
  • 1 motor for the Y-movement
  • 1 motor for the Z-movement
  • 1 motor for opening/closing the grabber

Next to that, 6 sensors are used for the positioning:

  • 2 touch sensors at the base
  • 1 color sensor for the Y-movement (5 stopping places)
  • 1 color sensor for the Z-movement (3 stopping places)
  • 2 touch sensors to stop the hoist at the end positions

Two EV3's (one to control the base, one to control the hoist). Using the EV3 daisy chain functionality, the crane can be controlled as one construction. It get's its input from a PC application, but it is easy to rewrite the software that it can be controlled by another EV3 brick.

Hi Hanso, you presented a great piece of machine, in which is obviously invested lots of time and effort. Unfortunately, it seems that you have presented this machine here on EB after you have already show it on Lego World Utrecht 2015.

According to the TC8 Information topic, this is not allowed. So, this model cannot be entered into the competition. This is to make sure that every model in this competition is build for the competition.

Sorry, didn't read the regulation in detail. Of course, I understand that my entry will not be entering the competition due to this rule.

This is some top-notch work, even if it's not allowed in the contest. The conveyor system is a great alternative to running large tracks and the flipper mechanism at the end is probably my favourite part of the system. Great job, even if you don't get a single vote.

Thanks for the compliment. At Lego World, the Delivery station was most popular. Especially the fact that the train is tilted. One of the visiting kids said "that's not a nice way to get out of a train" :wink:.
