Have you ever thought why robotic hands were invented? And who introduced this idea? First, at 1960s Dr.Engelberger invented the first robotic hand and the function of this hand is similar to the human hand. However, some researchers are trying to develop on it so it can be easily used by people with disabilities to do certain tasks. Robotic hands can give back hope to those who lost it. Moreover, it can be used by normal people to perform their tasks like doing house chores or helping them with drinking a juice etc. Also, robotic hands can be made from iron, wood, and cardboard. To make us work in a team, we we’re asked to make a robotic hand that can hold a fork and eat. To design our own robotic hand, we first took into consideration the …show more content…
In this stage, we also made sure to cut the thick wood board to fit the palm and wrist. So, now in total we have small pieces of wood plus two thick boards for palm and wrist. Once the wood was ready, we started to join the small pieces together by using the hinges and screws. This was doing by using a drill to make a hole so we can attach the hinge by plugging in the screw in the hole. Next, we joined them with the board for the palm by using the same technique which is by hinges and screws. So basically, one hinge between each finger joint and between each finger and the palm. The idea was very simple, all we had to do was join the finger pieces and then join them to the main board. Now after we did that, we attached the hand to another board for wrist using just the screws. Second of all, we used the eyehooks that was inserted on each finger and the palm as well. The purpose of the eyehooks is to attach the wool wire to it in order for the fingers to move or bent. Well, you’re probably expecting that the next step would be to run the wire through the fingers and palm and yes you’re right! Then we joined the wire to a glove using five key rings as shown in the

...ches with the form. Check the reference pictures and do not guess at this. Here is where drumming can become a major problem. Although the skin is thin in this particular area it still dries and shrinks and without proper pinning it will more than likely drum. So once in place, pin the brisket area with as may pins as needed because they can always be removed after the mount has dried. Rotate the form once again to the upright position and staple the cape to the back of the form about one to two inches from the edge. Cut the excess cape away and tie off the thread from sewing the cape.

The first step I took was to paint all of the wood white. After that I put wallpaper on the board that I am going to nail the rat trap to. I then attached the measuring cup to the rat trap by drilling a hole in the middle of the measuring cup and then using string to attach the cup at both the drilled hole, and the hole at the bottom. Then I nailed the rat trap into the board with wallpaper. That board was then nailed into the base.
Pivot Joint This type of joint is also known as a rotary joint and allows only one type of movement, rotational movement which occurs when bone rotates on or around another bone, an example of this type of joint includes the joint of the first and second vertebrae of the neck that allows the head to move back and forth, the joint in the wrist which allows the palm to be turned facing upwards and facing downwards, this type of joint is incredibly important because it allows the bones to move freely while rotating, without this type of joint we wouldn’t be able move our head or our hands and wrists. The bones in a pivot joint are connected by ligaments to allow flexible side to side movement. Different types of bones are connected in a joint, for example, irregular bones like the vertebra and the skull is connected in a pivot joint. Hinge Joint
...ter screen an arm that was placed onto his stump. When Ture Johanson saw his arm on the computer screen, he was able to control his own movements using his own neural command. In this particular study, Johanson was asked to perform numerous movements with his phantom hands such as driving a racecar. By driving a racecar, Catalan found that the subject moved muscles at the end of his existing arm to show the intent of moving his missing hand. From this study, subjects who had been experiencing PLP for several years had longer periods without pain and had shorter periods of intense pain. In addition, the phantom hand was relaxed from a tight fist to a half-open position. This study is different from others because the control signals are retrieved from the arm stump, and thus the affected arm is in charge. Moreover, it uses the signals from the damaged limbs itself.
Gloves are the protective clothing used to cover hands. These protective clothing were part of our history, since primitive times. Earlier, long sleeve clothing was used as mittens and gloves in many countries for protecting hands from weather elements, chemicals, and while working near a fire. However, today this clothing combines diverse aspects of safety and aesthetics. This post discusses history, and different types of gloves in use.
An evolving mother-daughter relationship is the focus of Jamaica Kincaid s autobiographical The Circling Hand. Like the narrator, Kincaid grew up in Antigua as the only child her mother and carpenter father. Also like the narrator, Kincaid admits her mother kept everything she ever wore. This narrative is a coming of age story, in which this dynamic and unusual mother-daughter relationship plays an important role. Through the beginning bliss of childhood to the frustrating stage of adolescence, this unique relationship, in which the daughter is infatuated with her mother, seems to control the narrator s development as a freethinking person.
Iron nail (1) Paperclips (several). Power supply (1) Coil (1) Method: - - - The method is relatively systematic. We first allocated various people amongst our group to collect different equipment such as the iron nails, paperclips, coils and power supply. Following that, we connected everything securely and wrapped the coil five times around.
One day Tom was going to his job at welding with robots. When Tom got there he asked his boss how can we make these machines more efficient. I do not know how they are going to do that but someday we will perfect the perfect machines that will weld perfect on cars. Well get going and start thinking of some ideas that would help us improve the robotic arms. Then the next day tom arrived at work he has an idea that can work. He made up a program that can make the welds more precise. They tried the program on the machines and it worked perfectly and it did not have any flaws. So after that they decided to keep the program . Tom was paid more money the company made more money. How has robotic welding made welding more efficient.
To pinch the sapling, movement involve is opposition of thumb and point finger. To bury the hole, the movements involve are flexion and extension of PIP and MP joint.
Haven’t you ever looked at your palms and ever wondered what the lines of your hands reveal about yourself that you didn't know before? well today is your lucky day I will tell you how to read your own palms.

According to a study done by Strokoe et al. (1976) it was found that there are 19 different ways of configuration of hands into meaningful shapes. For example, palm opened, closed fist with index finger pointing, etc;
Woodworking, a form of carpentry, has been around for centuries and overtime developed into a more modern art. Today people will mostly see woodwork in homes in the form of furniture and decorations, or even smaller things such as family heirlooms passed down by generations and simple crafts made by younger generations. The skill of woodworking, however, is not inherited but takes practice and years of experience to fully master. Even experienced woodworkers run into challenges sometimes. The key is to overcome that obstacle and find different ways to create something new from a piece of wood. It is interesting to see and go through the process in which a woodworker goes through
