Abstract

A apparatus includes an a exoskeleton system with a plurality of sensors for generating signals indicating a current motion and a current arrangement of at least the exoskeleton system, a hip segment, and at least one lower limb. The lower limb includes thigh and shank segments for coupling to a lateral surface of a user's leg. The thigh segment includes a first powered joint coupling the thigh segment to the hip segment, a second powered joint coupling the thigh segment to the shank segment, and a controller coupled to the sensors, the first powered joint, and the second powered joint. The controller is configured for determining a current state of the exoskeleton system and a current intent of the user based on the signals and generating control signals for the first and second powered joints based on the current state and the current intent.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Provisional Patent Application Serial No. 61 / 386,625, filed September 27, 2010, and entitled "Mobility Assistive Devices," the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to the field of powered auxiliary equipment, in particular to the powered auxiliary equipment and method. Background technique [0004] There are currently about 262,000 people with spinal cord injury (SCI) in the United States, about 12,000 new injuries are maintained each year, and the average age of injury is 40.2 years old. Of these, approximately 44% (5300 cases per year) resulted in paraplegia. One of the major barriers to paraplegia is loss of mobility, especially when injured at a younger age. Surveys of paraplegic users have shown that mobility problems are among the most prevalent, with mobility hopes primarily the ability to walk and ...
