In this attachment two knob wheels "(32072 ) Technic Gear 4 Knob" engage at 90 degrees angle. One of the knob wheels is a part of the robot and the other is a part of a pinless active attachment. This attachment is an example of how not to build an active attachment. These are some of the reasons why:
- When you use only "(32072 ) Technic Gear 4 Knob" the attachment will start to jump when it is rotated in some directions. This happens according to the forces in the knobs. That leads us to the next reason why you should not to build attachments in this way.
- You have to remove the attachment "jumping". This makes the attachment bigger, harder to attach and time consuming to design and build.
Build the attachment and experiment. See for yourself how it "jumps" up and down when the knob wheels are rotating and you hold the lever by hand.
