[0019] Working process and principle of this embodiment: At the initial moment, food can be placed at any position on the dinner plate base 15. The three-axis and double-screw module connects the redundant mechanical arm with a flip spoon at the end and the redundant mechanical arm with flip chopsticks at the end by installing 3D screw cover 19 and 3D screw cover 210 respectively. Screw 15 and screw 26 can control the two mechanical arms to rise and fall smoothly to a suitable height. The double-screw fixed base module fixes the dinner plate base 15 and the dinner plate base 216, and can fix the screw to ensure that they are within a certain range and operate smoothly. The redundant mechanical arm with flip chopsticks at the end is connected to the end through the steering gear joint arm 4 and the steering gear joint arm 5. The steering gear 5 76, the steering gear 6 81 and the steering gear 7 86 can control the rotation and translation of the mechanical arm to expand its accessibility. The structure of the end main gear 90 and the end sub-gear 89 can make the chopsticks rotate in multiple dimensions in the horizontal plane, and the end rotating frame 29 can make the chopsticks rotate in multiple dimensions in the vertical plane. The combination of the two enables the chopsticks to rotate in all directions and approach the food according to the algorithm. The temperature and posture of the food to be taken are detected by the installed camera 99, temperature measuring device 100 and laser 101. After confirming the posture information, the high accessibility and stability of the mechanical arm are used to use the thick head 1 22 and the thick head 2 23 of the clamping chopsticks to grab or roll the food to the designated place for feeding or pass it to the flip spoon 17. The redundant mechanical arm with a flip spoon at the end is connected to the end through the servo joint arm 1, the servo joint arm 2 and the servo joint arm 3. The rotation and translation of the mechanical arm are controlled by the servo 2 62, the servo 3 67 and the servo 4 74 to expand its accessibility. The flip spoon 17 is connected to three flip motors to realize the full reception of the food passed by the thick head 1 22 and the thick head 2 23 of the clamping chopsticks, and can also scoop liquid for feeding. The two can complete the task of auxiliary feeding separately, or work together to complete the feeding assistance together.

[0020] The redundant robotic arm modules in the modular spoon-and-chopstick collaborative eating auxiliary dual redundant robotic arm device of this embodiment can not only load and take different types of food respectively, such as the end clamping chopsticks to pick up block-like food or roll up noodles and other strip-shaped food, the end spoon to pick up soft food or liquid, etc., but also work together to put the food picked up by the clamping chopsticks into the spoon before eating. The parallel structure of the temperature measuring device, camera and laser set at the end of the redundant robotic arm with flip clamping chopsticks at the end can realize the coordinated monitoring of the end of the spoon and the all-round detection of food. The setting of the end rotating frame can make the clamping chopsticks at the end rotate in all directions, and allow the wire to pass through without affecting the normal operation of the clamping chopsticks, ensuring that the chopsticks can not only grab vertically downward, but also feed horizontally forward. The flipping motor in the redundant robotic arm with flipping spoon at the end can make the flipping spoon at the end flip in multiple directions. Through the cooperation between the various components, the horizontal angle of the spoon can be guaranteed to be stable, and the feeding posture of the spoon can be changed, and the control and grabbing can be flexibly switched. The setting of the redundant robotic arm module can ensure the flexibility of the overall structure and avoid the influence of the dead angle of the joint on the reachable range of the end components. The three-axis and double-screw modules enable the redundant robotic arm module to achieve a large range of lifting and lowering, ensuring the stability of the overall structure. The device of this embodiment uses a reasonable spatial layout to fix the various components in the device within a certain spatial range, while also achieving all-round capture of food information and efficient feeding of special groups of people. It is an auxiliary tool that combines intelligence, convenience and efficiency, and is particularly suitable for daily life support for special groups of people. It has important application prospects in automation assistance, elderly care and disability assistance, social care, etc.

[0021] Beneficial effects of this embodiment: A modular spoon and chopsticks collaborative eating assistance dual redundant robotic arm device of this embodiment uses computer, sensor, information, communication, artificial intelligence and automatic control technologies. Through the modular robotic arm, it can perform precise operation and flexible use, and can further help the elderly, disabled people and patients with limited mobility to complete daily eating. The device of this embodiment is flexible in operation, adaptable and can perform autonomous feeding. On the one hand, it can give users more self-care ability, and on the other hand, it can also enhance the user's mental health and sense of social integration.
