The ClimbingRobot will weigh approximately 100 times the biggest Roach, so the proportion of parts based on the weight is as in column 3. The geometrical data related to the ClimbingRobot above can be reduced by 1/10 if we assume a size proportion, instead of a weight proportion (column 4), but the load will still be x100! Probably a roach can have only one spine per leg engaged.

	Roach	Main.ClimbingRobot (x 100!)	Main.ClimbingRobot (x 10)
Weight	<20 g	2 kg	200 g
Leg	10 mm	1 m	10 cm
Foot	2 mm	20 cm	20 mm
Spine diameter	0.1 mm	10 mm	1 mm
Spine length	3 mm	30 cm	30 mm
Max asperity (Rz?)(*)	30 um	3 mm (our wall)	0.3 mm

(*) Assuming an average arithmetic Roughness, Ra of 3 [um] (a very smooth surface, like a machined metal part)

Some thoughts on other ways to scale spines in NotesOnScaling?
