I was wondering, the way the Omnibot 2000 claws are set up, it seems a solenoid may be able to make them open with a spring acting to close them. Is this possible? and if so is it a good idea due to the fact that solenoids are usually high voltage and I can not seem to find a digital one, are they able to connect with the EZ-B? Please let me know if this is a good idea? Thanks.
