Abstract
A robotic structure having a low mass, capable of providing seven degrees of freedom, and movable in a hemispherical workspace. The robotic structure includes several platforms connected by actuatable longitudinal members and movable joints made of intersecting or interwoven wire members.
Claims23
A low mass robotic arm comprising:
- a base platform;
- an effector platform;
- means for supportively spacing and connecting said base platform and said effector platform, said means for supportively spacing and connecting said base platform and said effector platform comprising interwoven movable joint means intermediate said base platform and said effector platform;
- linear actuator means operatively connecting said base platform and said effector platform;
- and
- means for selectively actuating each of said linear actuator means to operate said robotic arm.

A low mass robotic arm having at least seven degrees of freedom, capable of moving substantially throughout a hemispherical work space comprising:
- a base platform;
- at least one joint platform;
- an effector platform;
- means for supportively spacing and connecting said base platform and at least one said joint platform, said means for supportively spacing and connecting said base platform and at least one said joint platform comprising first interwoven movable joint means intermediate said base platform and at least one said joint platform;
- first linear actuator means operatively connecting said base platform and at least one said joint platform;
- means for supportively spacing and connecting at least one said joint platform and said effector platform, said means for supportively spacing and connecting at least one said joint platform and said effector platform comprising second interwoven movable joint means intermediate at least one said joint platform and said effector platform;
- second linear actuator means operatively connecting at least one said joint platform and said effector platform;
- and
- means for selectively actuating each of said linear actuator means to operate said robotic arm.
