Hi everyone! I’ve completed a major upgrade to my Bubble Lifter in my B9 Robot. This is a whole new design and concept from my old bubble lifter. The old way was a fork design operated by a very expensive super HD servo. Once power was shut down it would leak down under the weight of the bubble. Also it was kind of jerky and the servo was getting weak to the point I had to install a spring assist just to make it work. Here's a couple pics of that old design:

I hated to see that old lifter go but it just didn't hold up to expectations.

This new design is very smooth and powerful. I use a DC worm gear motor to power the lift with an offset cam design to to move the platform up and down. An added bonus is that the worm gear motor will stay in position when powered down!

Here's a vid of my new design. Enjoy the video and feel free to comment. Happy Building!
