How much will the whole device weigh including air muscles and pneumatic pumps, and controller?
The Hand system itself weighs under 4kg. You will need a pneumatic supply, but that can be a long way away, just running a thin air-line to the Hand. The PC does not need to be on-board; we currently use a little Mini-ITX system, but a smaller embedded system could be used. The compressor weight depends on your noise budget; a “silent” (i.e. <38dBA) compressor will weigh 15kg, but a very noisy compressor might weigh 1-2 kg.
