Embodiment Construction

[0018] The invention will be described in detail below with reference to the drawings.

[0019] Such as figure 1 , 2 As shown in and 4, a soft manipulator crutches, including crutches base 1, soft manipulator 2, three-dimensional four-way air pipe joint 3, gas delivery pipe 4, micro air pump 5, control valve group 6, and equal diameter cross four-way joint group 7. Light bulb 8, rod body 9, rod head 10, lighting control switch 11 and manipulator control switch 12; the soft manipulator 2 includes three soft fingers uniformly distributed in the circumferential direction; the soft manipulator uses two-component room temperature silica gel (RTV-2 ) It is made of vulcanization, which has good flexibility and toughness; the outer top surface of the soft finger is provided with three movable knuckles 21 integrally formed and arranged at intervals. The movable knuckles 21 are semicircular and move adjacently. The gap between the knuckles makes the soft fingers easier to bend; the outer b...

Abstract

The invention discloses a soft manipulator crutch. Existing crutches can only be used as simple walking-assisting instruments. A soft manipulator of the soft manipulator crutch comprises three soft fingers uniformly distributed in the circumferential direction; the top surfaces of the outer parts of the soft fingers are provided with three movable knuckles; and the inner parts of the soft fingersare provided with air cavities corresponding to each movable knuckle position. When the soft manipulator crutch is used as a common crutch, the soft manipulator is a ground palm of the crutch; and when the soft manipulator crutch is used as a common manipulator, a control switch of the manipulator is closed, a micro air pump is started, two-position three way solenoid valves of three control valvegroups are energized, the micro air pump supplies air to each of the three air cavities arranged radially from the inside to the outside in the soft fingers through the three control valve groups, the air pressures of the three air cavities arranged radially from inside to outside in the soft fingers gradually decrease, and the soft manipulator bends to pick up items on the ground.

Description

Technical field [0001] The invention belongs to the field of walking aids, and particularly relates to a soft manipulator crutches. Background technique [0002] Crutches are a tool that the elderly often use in their daily lives. The crutches currently on the market have a single function and can only be used as a simple walking aid. If an elderly person falls during walking, he needs to ask others for help or bend down to pick it up. Elderly people have inconvenience, and bending over is a burden to the body, which is prone to accidents and threatens health. Therefore, it is necessary to design a new type of crutches that can help the elderly pick up objects on the ground. Summary of the invention [0003] Aiming at the shortcomings of the existing crutches, the present invention provides a soft robotic crutches, which can help the elderly who are inconvenient to bend to pick up objects on the ground quickly, and has the advantages of simple structure, portability, lightness,...
