For EPro8 we created a crane. We started bottom to top to make it less harder. In the process it was quite hard building. We had a few ideas and some of the plans failed but at the end we finished it off. We had extra support on the sides to make the build stable. We also put 4 poles at the bottom to make even more stabilized. We were able to hold a object with the string(the hook), able to hook it up or down, and turn it. This was a fun, confusing challenge.
