Description

Robot arm for education

Technical Field

The utility model relates to an education equipment field specifically is a robot arm for education.

Background

With the development of science and technology, various electronic products are more and more popularized and appear in common families, and meanwhile, the living habits of people are greatly changed due to the appearance of the internet and the lower and lower prices of the broadband. In order to promote the children to learn, different robots with entertainment are available in the market.

Autism, also known as autism or autism disorder, is a representative disease of pervasive developmental disorders that commonly exhibit symptoms including spontaneous behavioral abnormalities, lack of communication, sudden onset, and the like. Autism makes it difficult for children to adapt to normal society, resulting in a future disadvantage in society and to date there is no particularly effective treatment. Experts generally consider autistic children more beneficial to receive education in mainstream schools than special schools, as they can learn to interact with each other, control and modify their behavior. Meanwhile, in the field of robots for adjuvant therapy of autism, there are currently approximately three well-known brands, KASPAR, NAO and Milo. Milo was developed by Robokind, but has the disadvantage of being fragile in joints and lacking tactile sensors around the body, which do not allow tactile interaction. NAO was developed by SoftBank Robotics, who lacked the human favorite face. KASPAR was developed by the university of herford's adaptive systems research group, and the robot's face exhibited a series of simplified expressions and had movable arms, face and eyes, which could be controlled by the parent or teacher, and could be fed back in response to the child's sense of touch.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1-3, the whole front and back structure of the present invention is shown. The core layer 14 of the hand 12 of the present invention comprises three grooves, wherein the groove 16 is used for mounting the FSR sensor 18; the FSR sensor 18 is shaped as shown in FIG. 4;

the recess 20 is for mounting an RFID sensor 22, and the recess 20 is located on a base 24. The RFID sensor 22 is shaped as shown in FIG. 5;

the recess 26 is used for mounting a magnet (not shown). The magnet may be a permanent magnet or an electromagnet.

The cut-out shapes of the

recesses

16, 20, 26 are adapted to the respective mounted component.

The core layer 14 is formed of a plastic material such as polylactic acid, polyethylene, polypropylene, polystyrene, polyamide, ABS, polycarbonate, PMMA, or the like; core layer 14 may be made by injection molding, injection or 3D printing or other suitable manufacturing method. The

recesses

16, 18, 20 in core layer 14 are such that the assembly is substantially flush with the surface of the core layer and does not protrude above the surface of core layer 14.

FIGS. 6-9 are schematic views of a hand 12 of the robot 10; wherein the surface of core layer 14 is covered with a layer of skin 28. The skin 28 is partially peeled away in fig. 6, 7, showing the FSR sensor 18 in the location of the recess 16. Fig. 8 and 9 show the

electrical connectors

30, 32 and a portion 22 of the RFID sensor located within the base 24.

Electrical connectors

30, 32 are used to connect the FSR sensor 18 and the RFID sensor 22 to a power source and processing center, and when the magnet is an electromagnet, will also be connected to the power source and processing center through the

The skin 20 has a thickness of 2mm-3 mm; consisting of silicone or polyvinyl chloride.

Fig. 10 shows the position relationship of the present invention when it is connected to 10. in general, the present invention can be adapted to the educational robots of KASPAR, NAO and Milo, and the size of the volume thereof needs to be modified accordingly.

The relative position of objects equipped with complementary magnets and RFID tags in the housing 40, and already placed on the hand 12 of the robot 10, is disclosed in fig. 11-13. The housing 40 is detachably connected to the object. The housing 40 may be attached to any suitable object and removed again in the non-operative state. The RFID tags are reprogrammable and interchangeable within the housing 40 so that the housing 40 can be removably attached to different appendages and programmed according to different feature details of the object. The RFID tag can be programmed according to the methods described in the prior art, such as the methods described in patents CN102365646, CN103065166 or any other existing documents, and the present invention does not improve the programming method.

In general terms, the educational object (child) of the present invention is placed under supervised conditions near the robot 10 equipped with the hand 12, interacting through a plurality of scenes preset in the programmed robot 10, which may be automatically controlled or controlled by supervisors (teachers, parents, guardians, medical staff, etc.) through control devices.

These scenarios may be educating children to identify suitable tableware for eating a particular food; in this case, the robot 10 is programmed to say that he is hungry and wants to drink soup, asking the child to drink an object for soup to the robot 10. And gives the child the choice of toothbrush 34, fork 36, and spoon 38 that the child needs to select the correct object for robot 10. In this scenario, the object would be scoop 38, and after the child applies the appropriate force to impart the object to robot 10, the complementary magnet located inside housing 40 retains the corresponding object in hand 12 of robot 10; and identifies the object using the FSR sensor 18 and the RFID sensor 22. Robot 10 provides verbal or other feedback to the child based on the object, which may be "thank you, spoon is best" or "fork may not work, soup will slide in the gap" or "toothbrush is used to brush teeth". Additionally, if the child has imparted 10 an object with too much force, the robot may provide verbal feedback such as a "pain" to the child to recognize that they have applied too much force.

Similarly, the present invention does not provide any improvement to existing programming within the robot 10, which may result in differences in programming built into the robot depending on differences in the model, brand, etc. of the robot 10.
