I am currently in the process of scratch building Sapporo, a 1/5 scale R/C
controlled Tachikoma. When he is done he'll be about 18" tall.
I've been having fun figuring out what parts to buy and techniques to use
in the build. The inner structural elements are laser cut 1/8" masonite, and
the skin is currently metallic blue art paper laminated to poster-board, also
cut via laser cutter. All of the base modeling is being done in Lightwave 3D,
then sent through Pepakura to create the vector artwork for generating
either the skeleton for the inner masonite support structure, as well as the
shapes that create the paper/posterboard skin.
I was planning on using Mecanum wheels direct mounted on mini-metal
gearmotors, VEX electronic speed controllers, and standard R/C
transmitter/receiver electronics. After some field testing, I've so far managed
to fry one of the motors, and have determined that for now the mecanum
wheels will have to be set aside for standard wheels. The current chassis has
too much flex in the legs, and the design of the mecanums creates too much
extra rolling friction for the torque available from the current motors that are
being used.
