Multi-fingered robotic hand
A robotic hand is presented having a plurality of fingers, each having a plurality of joints pivotally connected one to the other. Actuators are connected at one end to an actuating and control mechanism mounted remotely from the hand and at the other end to the joints of the fingers for manipulating the fingers and passing externally of the robot manipulating arm in between the hand and the actuating and control mechanism. The fingers include pulleys to route the actuators within the fingers. Cable tension sensing structure mounted on a portion of the hand are disclosed, as is covering of the tip of each finger with a resilient and pliable friction enhancing surface
3D Printed Soft Robotic Hand
Soft robotics is an emerging industry, largely dominated by companies which hand mold their actuators. Our team set out to design an entirely 3D printed soft robotic hand, powered by a pneumatic control system which will prove both the capabilities of soft robots and those of 3D printing. Through research, computer aided design, finite element analysis, and experimental testing, a functioning actuator was created capable of a deflection of 2.17” at a maximum pressure input of 15 psi. The single actuator was expanded into a 4 finger gripper and the design was printed and assembled. The created prototype was ultimately able to lift both a 100-gram apple and a 4-gram pill, proving its functionality in two prominent industries: pharmaceutical and food packing
Multi fingered robot hand in industrial robot application using tele-operation
This research focuses on the working and development of wireless robotic hand system.
In this research previously developed models have been studied. After analysis of those
models, a better approach has been presented in this research. The objective of this
research is to design and develop a tele-operated robotic hand system. The robotic hand
is intended for providing solutions to industrial problems like robot reprogramming,
industrial automation and safety of the workers working in hostile environments. The
robotic hand system works in the master slave configuration where Bluetooth is being
used as the communication channel for the tele-operation. The master is a glove,
embedded with sensors to detect the movement of every joint present in the hand, which
a human operator can wear. This joint movement is transferred to the slave robotic hand
which will mimic the movement of human operator. The robotic hand is a multi
fingered dexterous and anthropomorphic hand. All the fingers are capable of performing
flexion, extension, abduction, adduction and hence circumduction. A new combination
of pneumatic muscles and springs has been used for the actuation purpose. As a result,
this combination reduces the size of the robotic hand by decreasing the number of
pneumatic muscles used. The pneumatic muscles are controlled by the opening and
closing of solenoid valves. A novel technique has been used in the robotic hand for
tendon routing, which gives the ability of independence to all finger joints. The heart of
all the control mechanism of the system is mbed microcontroller. The designed system
was tested at different module levels. The results show the successful establishment of
communication between master and slave at a rate of 10 packets per second, which was
sufficient for smooth motion of the system. The amount of torque produced at all the
joints in the robotic hand has been presented in this research. The posture tests have
been performed in which two fingers were actuated which followed the master. This
system has achieved motion of fingers without any tendon coupling problem. The
system is able to replace the human industrial workers performing dexterous tasks
Robotic hand project
Eldivene monte edilmiş esneklik sensörleri yardımıyla insan elinden alınan konum bilgileri ile mekatronik tabanlı robotik elinin kontrolü sağlanmıştır. İnsan elinin parmaklarının açısal hareketleri algılanarak bir mikrodenetleyici tarafından işlenir ve servo motorlar yardımıyla robotik el kontrol edilir. Yapılan testlerde robotik elin, eldiven giydirilmiş insan elinin hareketini taklit edebildiği görülmüştür. Bu robotik el otomasyonda ve insan için tehlikeli ortamlarda tutma işleminin uzaktan kontrolü için kullanılabilir. Robot el, üzerine sıcaklık algılayıcıları monte edilebilecek şekilde hazırlanmış olup, bunları kullanmakla amaçlanan; robot elin tuttuğu cismin sıcaklığını eldivende hissedebilmektir.In this work, the mechatronic based robotic hand is controlled by the position data taken from the glove which has flex sensors mounted to capture finger bending of the human hand. The angular movement of human hand’s fingers are perceived and processed by a microcontroller, and the robotic hand is controlled by actuating servo motors. It has seen that robotic hand can simulate the movement of the human hand that put on the glove, during tests have done. This robotic hand can be used not only in automation, but also handling operations in dangerous environment for people. The robotic hand is prepared for adding temperature sensors on it. By the help of temperature sensor integrated to the robotic hand, temperature information can also be monitored
AER Neuro-Inspired interface to Anthropomorphic Robotic Hand
Address-Event-Representation (AER) is a
communication protocol for transferring asynchronous events
between VLSI chips, originally developed for neuro-inspired
processing systems (for example, image processing). Such
systems may consist of a complicated hierarchical structure
with many chips that transmit data among them in real time,
while performing some processing (for example, convolutions).
The information transmitted is a sequence of spikes coded using
high speed digital buses. These multi-layer and multi-chip AER
systems perform actually not only image processing, but also
audio processing, filtering, learning, locomotion, etc. This paper
present an AER interface for controlling an anthropomorphic
robotic hand with a neuro-inspired system.Unión Europea IST-2001-34124 (CAVIAR)Ministerio de Ciencia y Tecnología TIC-2003-08164-C03-02Ministerio de Ciencia y Tecnología TIC2000-0406-P4- 0

Ground Robotic Hand Applications for the Space Program study (GRASP)
This document reports on a NASA-STDP effort to address research interests of the NASA Kennedy Space Center (KSC) through a study entitled, Ground Robotic-Hand Applications for the Space Program (GRASP). The primary objective of the GRASP study was to identify beneficial applications of specialized end-effectors and robotic hand devices for automating any ground operations which are performed at the Kennedy Space Center. Thus, operations for expendable vehicles, the Space Shuttle and its components, and all payloads were included in the study. Typical benefits of automating operations, or augmenting human operators performing physical tasks, include: reduced costs; enhanced safety and reliability; and reduced processing turnaround time
