Pound for pound, cvg Douglas fir, for example, is stiffer than aluminum, and has better strength in compression and sheer. Aluminum wins for better impact resistance, and possibly strength in tension. The mistake would be to make a wooden robot just like you would make an aluminum one. The design and building method has to be tailored to the strengths of the material you choose.

Dude, I didn’t say anything about the wood being heavy, people need to lighten up a little around here. I know wood can be lighter; I have used it myself for many projects, like our automated couch. I was referring to the weight because there is a B&S engine on the bot….
