First, let’s build the simplest worm gear box – credit goes to Builderdude35, where we initially saw this simple build. But, it’s quite a popular design that seems based on a LEGO Technic part. The below provides roughly the same building instructions as Builderdude’s in pictorial rather than video format…

I was working mainly on demonstrations to students working on the VJC East Zone 2019 Robotics Challenge (Exploration) – so, lifting boxes and manipulating tennis balls. I came up with two designs that integrate with the LEGO EV3 Driving Base model.
- Velcro Lift – Reminds me a little of Electromagnet Cranes used in metal scrap yards…
(Uses the Large Motor – see link for torque-related specs)
- Fork Lift – Sort of a fork lift for tennis balls… although hard to release, once you’ve got one!
(Uses the Medium Motor – see link for torque-related specs)
See the peer coding page for generic code for simple EV3-based Remote-Control projects.
