I posted last month about the wooden robot automata made by Alan Westby. I just received word that he's finished another in the series. This one depicts a poor robot hurling through space just beyond the safety of its rocket ship. Thankfully, most robots don't require air.
Note the clever use of two sets of bevel gears used to create rotation in two directions off of the same drive shaft. Well played!
