GBC Chainable Camshaft Stepper Module

[Lasse D]

This is my latest GBC module:

A stepper module is nothing new in the GBC world. Most GBC steppers have pistons and work like in a normal piston engine with a crankshaft moving pistons up and down.

This design is a bit different from the typical designs in that it uses camshafts instead:

There are 9 steps which lift the GBC balls:

The driveshaft in the middle can be used to chain multiple modules:

This is shown in the video. It also shows how to chain the modules in a gentle curve. Here the slopes on the top can be turned to make sure that balls are directed into the inbox of the following module.

In the video you can also see this small circuit made from 10 modules. Two M-motors and one NXT motor power the 10 modules:

There are building instructions here: http://c-mt.dk/instructions/models_gbc-GBCStepper.htm

The module is based on this old one which I had at LEGOWorld back in 2011: http://www.brickshelf.com/cgi-bin/gallery.cgi?f=461558

Up next: I should take a look at the conveyor module... it didn't work too well at the last event.

That's excellent! I love how smooth the motion is, and how the balls appear to practically roll uphill. Well done!
