All Electric 6-DOF Motion Platform

Abstract:

The proposed innovation is a 6-DOF motion platform, using only 
electric motors and cable transmissions, with a +/- 90 degrees 
range of motion on all three rotational axes, a +/- 1 meter range 
of motion on all three translational axes, and a 5000 Newton /3250 
Newton-meter load rating. The proposed innovation addresses two 
aspects of the subtopic requirement. First: "...improvements to 
robotic joints..."; the proposed electric linear cable drive 
actuator is an innovation by itself. Second: "...improvements to ... 
mechanisms."; the proposed platform is an innovative motion platform 
mechanism providing faster response, smoother motion, and lower operating 
costs compared to conventional platforms. The Phase I project objectives are 
1) develop a proof-of-concept dynamic simulation of the proposed platform 2) 
use the simulation to determine the optimum physical characteristics, and 3) 
determine mechanism requirements and candidate components. The proposed Phase 
I effort is 8.5 man-months across a 6 month project duration and will produce 
complete hardware / software requirements and a specifications list for Phase 
II platform design and fabrication. NASA will gain direct benefit from the 
proposed platform for virtual reality applications involving motion and force 
feedback for Astronaut and robotic device training.
