Hot Melt Adhesive Climbing Robot

I had the pleasure to meet Fumiya Iida from the Bio-Inspired Robotics Lab at ETH Zürich at Robots on Tour. His group researches on unconventional locomotion (e.g. hopping) that uses passive mechanical dynamics for energy efficiency, and on thermoplastic adhesives (hot glue) in robotic applications. Here’s a video of their ultra-cool climbing robot that glues its foot to the wall with hot melt:

Evaluating 3D modeling software alternatives

Mey and I are considering several software alternatives that allow us to make the prototypes and send them to be 3D printed.

The ideal would be that we could use the same software on our different platforms. Mey is using OSX and I’m using Ubuntu GNU/Linux.

So far my favorite choice is FreeCAD, for several reasons. One, of course, is because it is free, with no restrictions or paid extra features. Another one is because I got used to SolidWorks at the University, and FreeCAD learning curve is less steep for me than, for example, OpenSCAD.
