The strict development processes of commercial upper-limb prostheses and the complexity of research projects required for their development makes them expensive for end users, both in terms of acquisition and maintenance. Moreover, many of them possess complex ways to operate and interact with the subjects, influencing patients to not favor these devices and shed them from their activities of daily living. The advent of 3D printers allows for distributed open-source research projects that follow new design principles; these consider simplicity without neglecting performance in terms of grasping capabilities, power consumption and controllability. In this work, a simple, yet functional design based on 3D printing is proposed, with the aim to reduce costs and manufacturing time. The operation process consists in interpreting the user intent with electromyography electrodes, while providing visual feedback through a µLCD screen. Its modular, parametric and self-contained design is intended to aid people with different transradial amputation levels, despite of the socket's constitution. This approach allows for easy updates of the system and demands a low cognitive effort from the user, satisfying a trade-off between functionality and low cost. It also grants an easy customization of the amount and selection of available actions, as well as the sensors used for gathering the user intent, permitting alterations to fit the patients' unique needs. Furthermore, experimental results showed an apt mechanical performance when interacting with everyday life objects, in addition to a highly accurate and responsive controller; this also applies for the user-prosthesis interface.

“…Recently, the structural design of the robot hand using the wired-driven mechanism as the movement mechanism became popular among researchers [ 4 , 5 , 6 , 7 , 8 , 9 ]. However, it is found that the use of wire or flexible linkage in this approach gives inaccurate joint movement due to the mechanical properties of the cable.…”

“…However, the structure of the robot is weighty as compared to that of a plastic material and is thus not suitable to be used as the material for a prosthetic hand. Over the years, there has been advancement in terms of the use of new plastics and other materials such as carbon fiber in the construction of hand prosthetic structures and 3D printing technology is also in line with this demand [ 5 , 7 , 9 , 15 ]. Furthermore, detachable finger structure and mechanical stopper are crucial features, which are useful for finger replacement and joint protection purposes, respectively.…”

Trans-radial prosthesis is a wearable device that intends to help amputees under the elbow to replace the function of the missing anatomical segment that resembles an actual human hand. However, there are some challenging aspects faced mainly on the robot hand structural design itself. Improvements are needed as this is closely related to structure efficiency. This paper proposes a robot hand structure with improved features (four-bar linkage mechanism) to overcome the deficiency of using the cable-driven actuated mechanism that leads to less structure durability and inaccurate motion range. Our proposed robot hand structure also took into account the existing design problems such as bulky structure, unindividual actuated finger, incomplete fingers and a lack of finger joints compared to the actual finger in its design. This paper presents the improvements achieved by applying the proposed design such as the use of a four-bar linkage mechanism instead of using the cable-driven mechanism, the size of an average human hand, five-fingers with completed joints where each finger is moved by motor individually, joint protection using a mechanical stopper, detachable finger structure from the palm frame, a structure that has sufficient durability for everyday use and an easy to fabricate structure using 3D printing technology. The four-bar linkage mechanism is the use of the solid linkage that connects the actuator with the structure to allow the structure to move. The durability was investigated using static analysis simulation. The structural details and simulation results were validated through motion capture analysis and load test. The motion analyses towards the 3D printed robot structure show 70–98% similar motion range capability to the designed structure in the CAD software, and it can withstand up to 1.6 kg load in the simulation and the real test. The improved robot hand structure with optimum durability for prosthetic uses was successfully developed.

“…Recently, some of the researchers have produced robots that have incomplete fingers that do not resemble the actual anatomy of the human hand. They applied the cable-driven actuator mechanism into structural design [13][14][15][16][17][18]. We found that the mechanism negatively affects motion accuracy of the joint due to the elastic characteristic of the material itself [19,20].…”

“…We also found that robot structure made of metal [23] is heavy and difficult to be fabricated compared to a 3D printed product in terms of cutting and shaping the product. Currently, 3D printed technology has gained attention of researchers working on a prosthesis hand [14,16,18,24], and it became the fabrication method most frequently used for this purpose. This paper describes robot hand structural design that follows the average size of an adult human hand and fabricates it by means of 3D printing technology as a recommended fabrication method in the previous study.…”

Developing an anthropomorphic robotic hand (ARH) has become a relevant research field due to the need to help the amputees live their life as normal people. However, the current state of research is unsatisfactory, especially in terms of structural design and the robot control method. This paper, which proposes a 3D printed ARH structure that follows the average size of an adult human hand, consists of five fingers with a tendon-driven actuator mechanism embedded in each finger structure. Besides that, the movement capability of the developed 3D printed robot hand validated by using motion capture analysis to ensure the similarity to the expected motion range in structural design is achieved. Its system functionality test was conducted in three stages: (1) muscular activity detection, (2) object detection for individual finger movement control, and (3) integration of both stages in one algorithm. Finally, an ARH was developed, which resembles human hand features, as well as a reliable system that can perform opened hand palm and some grasping postures for daily use.
