I'm conducting an informal market survey to identify requirements for potential applications for a new type of actuator that is currently being refined for use in the aerospace industry. This technology has the potential to mobilize inspection robots in place of wheels or treads such as those currently used. To determine if this idea should be pursued, I need to know what specs would be required/desired of such a device. Of the inspection robots that exist today, what are their flaws/shortcomings that need to be overcome? Any insight would be greatly appreciated. Thanks in advance.
