Teddy the Artist

Craig Longhurst <craiglonghurst@...>

Hi everyone,

I've always been fascinated by drawing/writing mechanisms and recently stumbled across "Teddy the Artist" made by Yonezawa: https://www.grandoldtoys.com/toydb_Detail.php?id=526

Videos in operation here: https://www.youtube.com/watch?v=brx47OS90CM and https://www.youtube.com/watch?v=xCU2rzAMC28 (quite a few more on youtube)

What I like about this is the apparent simplicity of the cam - being the same shape as the picture to be drawn. Having said that I still can't work out how to design a cam follower / pen attachment to achieve this.

Any ideas?
