Add the following snippet to your HTML:. A robotic hand that emulate the movement of your hand wirelessly through a glove with sensors. Project showcase by Gabry This is my school project for the 5th year of high school I'm Italian, we have 5 years of high school. It consists in an artificial hand controlled by a glove with flex sensors. The artificial hand reproduces the movements of the hand with the control glove, wirelessly.
The hand and the glove works both with Arduino. This guide is still in development, sorry if some parts are not clear, I'll put some 3D images in future. To make the control glove I suggest first to choose the right position of the different components, then connect everything with the proper length of wire.

To make an analog read with Arduino LilyPad you need to make a voltage divider, since that flex sensors don't work like potentiometers they have only 2 contacts. So following the scheme, first solder the 5 resistor on the LilyPad board, one side to the 5 different Analog pins, the other in common to the ground.
Then solder the flex sensors, one side to the 5 different Analog pins and the other in common to the positive. Then connect the XBee Shield: two wires for the power, the oter two for the signal. Solder the Tx pin to the Rx and vice versa. And it still works! This is the most complicated part, because you have to choose the proper materials to make the hand, but it can be also easy if you have the possibility to 3D print the hand there are many different 3D projects on the web for printing hand parts.
I started making the fingers with cork, to find the proper structure for the movements, then I made it with a branch. So make three wooden cylinder per finger, two of them with 1 cm over the normal length of your phalanx, needed to fit one piece into another. Then with an angle grinder make the grooves to make the pieces fit together see the images, you'll understand better. Use a drill to make the holes for the hinge, then you have to make other two holes for the fishing wire, vertically, one towards the inside of the hand and one outwards.

So when the wires are set at the top of the finger, when you pull the one inwards the finger will close, and when you pull the one outwards the finger will open. The palm was problematic, because I made it initially with wood and the thinner parts always broke. So I decided to make it of steel and I've had no problems. Cut it and do some protrusions similar to those made for the fingers to fix them to the palm see the images as a reference.
Then use the drill to make the other holes for the fishing wire, the thumb will be tricky because it's not vertical as the other fingers. Afer making the hand, you need to make a support for the five servomotors and a support for the Arduino UNO boards.To browse Academia. Skip to main content. Log In Sign Up. Engr Rana M Shakeel. A Components assembling The arm control by robotics is very popular in the world of robotics.
It provides more interfaces to the outside world and has larger Memory to store many programs Approach: We were able to perform a detailed study of the robotic arm and the micro-controller. We also learnt and familiarized with the micro-controller using assembly language, and converting the assembly language codes to hexadecimal codes using a development board.
Mechanical Structure of the Arm: In constructing our arm, we made use of Two servo motors and a dc motors and gears since our structure is a three dimensional structure. A typical prototype that we employed is as shown in Figure. There is a servo motor at the base, which allows for circular movement of the whole Structure; another at the shoulder which allows for upward and downward movement of the Arm; while at last dc motor at the wrist allows for the picking of objects by the magnetic hand.
Program Counter: This is the "engine" which starts the program and points to the memory address of the instruction to be executed. Immediately upon its execution, value of counter increments by 1. Control Logic: As the name implies, it which supervises and controls every aspect of operations Within MCU and it cannot be manipulated.
They convert analog signals to digital signals.
Oscillator: This is the rhythm section of the MCU. The stable pace provided by this instrument allows harmonious and synchronous functioning of all other parts of MCU. Timers: timers can be used for measuring time between two occurrences and can also behave like a counter. The Watchdog Timer resets the MCU every time it overflows, and the program execution starts anew much as if the power had just been turned on. Methodology: The method employed in designing and constructing the robotic arm are based on the operational Characteristics and features of the microcontrollers, stepper motors, the electronic circuit diagrams and most importantly the programming of the microcontroller and stepper motors.
A sample robot which can rotate, magnetize an object, lower and raise its arm, by being controlled by the microcontroller is built successfully. The development board is soldered and it used the required procedure for the correct operation of the controller.Today, robotics is one of the best technologies which deals with design, working and applications of Robots, computer systems for their control and information processing.
This technology also deals with automated machines and is very useful in manufacturing process. As a result, many people show lot of interest on this technology from engineering level itself. For that reason, here we are listing out some useful and best robotics projects ideas for engineering students. These project ideas include some interesting concepts like line follower robot, bomb detection robot, fire fighting robot, DTMF based mobile phone controlled robot, etc.
So, if you are interested you may check this list of robotics projects ideas. Hiii sir, Am saraswathi. Am a EEE student. Robotic is the good and fantastic project to do the mini project in the colleges. I have selected the small and simple walking robot.
But i want some ranges of microchip and DC motor. I have searched different ways and different websites about the ranges of components ofsmall walking robot. Your email address will not be published.

Projects described in books or shown on Youtube seem absurdly easy, but I have yet come across a project that didn't need any tinkering before I could take it into a classroom. This one isn't too bad, but it still took me longer than I expected. I came across this robotic hand project on Youtube as well as teachengineering. Sure, I did have to try several different versions and had to make adjustments as I went along, but I'm not sure if this is something I can take directly into a classroom of 2nd graders without more tinkering.
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Tape Scissors Cardboard paper or cardstock paper Standard drinking straws Dollar Store variety is fine Pearl drink straws or bigger diameter straws Yarn or twine. Trace your hand on a cardboard or cardstock paper. Cut the traced hand out cutting it a little bigger than the actual tracing. Mark your finger joints on the cutout. Draw straight or curved line across it.
Fold the fingers at the lines. Cut smaller straws to size leave a little gap between the lines to facilitate in threading the yarn.
Tape straw pieces to the hand. Thread yarn through the straw pieces. Each finger will have a length of yarn of its own.
Thread all five pieces of yarn through the bigger straw. The threading part was difficult. If I had a big needle for the yarn, it would have made it easier, but I didn't. So, I struggled with it. If I do go forward with this one in the classrooms, I think I'll have to buy big plastic needles for this project. I had grand plans for making a sleeve that will cover the arm, but I'm not sure I'll be able to build all of that in an hour let alone a 2nd grader.
So, I might still try it, but I probably won't take it into the classroom. I think I'll buy different colored yarns for each finger, so the students will know which finger they are trying to move. With the same colored yarns, it was difficult to figure out which end went with which finger. Reply 9 months ago. Reply 10 months ago. That's a great idea! The best part is that I think even the kindergarten students will be able to thread them on their own.
Thanks, again! We wrap a small piece of trnasparent tape arpund the end of the string and twist it to be able to pull it through the straws; sort of like the ends of shoe laces. Reply 11 months ago.

In this project; 3D robot hand assembly, servo control, flex sensor control, wireless control with nRF24L01, Arduino receiver and transmitter source code are available. In short, in this project we will learn how to control a robot hand with a wireless glove.
The hand is part of an open-source project called InMoov. It's a 3D-printable robot, and this is just the hand and forearm assembly. For more information, visit the official InMoov website. Assembly of robotic arm parts is very detailed and complex, so you can visit the "Assembly Sketches" and "Assembly Help" pages in the InMoov website for more details on assembly.
Or you can watch the video I shared. When assembling the fingers, make sure the parts are oriented correctly before gluing. Keep all servo motors at 10 or degrees before attaching the servo pulleys to the servo motors. When mounting the servo pulleys, keep fingers in the closed or opened position according to your servo angles. Then wrap around the servo pulley until the braid wires or strings becomes stretched. At this point, the servos should already be mounted into the forearm. To connect them to the power supply and Arduino, you can use a small breadboard.
The flex sensors require a circuit in order for them to be compatible with Arduino. Flex sensors are variable resistors, so I recommend using a voltage divider.
I used 10K resistor. For the source code to work correctly, follow the recommendations:.
