Instructables
BTW!!!!! This instructable is awsomeeeeee


This is a very simple but at the same time a very hard project depending on your skill level. Lets get to building!

What this is, is a wireless animatronic hand that doesn't need a computer to operate. The user wears a control glove and can control the animatronic hand precisely. Bellow are some pictures of the final product:

Step 2: Control Glove

Picture of Control Glove
IMG_1449.JPG
Materials:
Arduino w/ ATMEGA 328
Xbee w/ Shield
5 Flex sensors
Glove
9v
Hook up wire
Custom PCB making tools
(5) 10k resistors







1. Power both of the Arduinos to make sure they operate correctly.
2. Assemble the Xbee radio shields.
3. Connect the Xbee shields to the Arduino by placing on top of the Arduino.
4. Connect the Xbee’s to the shields and connect them via USB.
5. Take the ATMEGA328 chip off the Arduino so there is a direct link between the computer and the Xbee radio.
6. Configure them in XCTU (default settings will work).
7. From here i built my own PCB (I'm not going to touch on how to do that, there are other very good tutorial out there)  I used the data sheet for the sensors from this site, this is also where i got these sensors:

8.From here i put all the boards together and tested it out to see if everything worked (powered on).
9. I sewed the flex sensors onto the glove by poking a hole at top and running the string over and under the sensor so it can still freely move.
10. i built the arm band with some elastically and some STRONG double sided tape.

It's possible with arduino UNO? I can't read more two signal in the serial port, why?

Is it possible to make a full-scale human body with the same principle as your Instructable?
Theoretically, yes, but I think overall you'd have to find some super strong servo's, some super strong yet flexible piping and alot of time to do it. but overall NO, you'd have to create a biped platform for it to move as a human, costing thousands.

The biped platform wouldn't cost thousands. I have seen biped robots that were human sized and only cost around 500 usd.

Oh, thanks for the answer.
Check out a video on you tube.
Search for 3d Printed humanoid.
The man has done amazing work building a humanoid robot with fantastic working hands and arms. His 3d files are free to download. He is also using Arduinos.

Its called InMoov

For strong servos you can look into using an H-Bridge to connect to a couple of DC motors and attach a Potentiometer to track its position by reading the Potentiometer and external power source. You can go as strong as you want.

Love this project! It has inspired me to build my own with a different design--a nice challenge for me. I'd like to know, though, how much did you purchase the flex sensors for? I'm broke and looking for something that I don't have to spend a fortune on. Most of what I've found online has been around $13.

you can make your own. I have seen some people on here who have done so, but I am unsure of how well they work

this projet can help disabled man?that's great!

It actually can't. There are certain things a real hand has that this one is lacking.

So, In theory, if I were to rig this up in such a way to mimic my body, I could have a robot that would do exactly what I did?

Actually I am working on a project right now to do so. But you wouldn't want this hand, as its biology is very different from any humans, and it would be a piece of shit if you wanted to actually pick something up. I would recommend you use a 3d printed hand (such as the one from inmoov) if you wanted to do something like that, Also you would need a rotational sensor to detect certain movements (such as the forearm turn).

hi :) could you email the coding and circuit diagram please djalex2134@gmail.com

very interested in this and want to make it !

i appreciate it if you can ! :)

Hello,

Please can you tell me a measurement soft for the bend sensors values.

Thank you!

Hey! Is there anyway you can take a clear picture of all the bread board wiring, and the printed pcb? I'm having trouble reading your schematic. Thanks!

How much would this cost?

i program my xbee in transparent mode but, i only can control one servo with one flex sensor , is necesary change the configuration of the xbee ?? or is the code of arduino?

Evan81511 months ago

Can you do this with an arduino mega cause i see that you say you have to remove the atmega328 chip, but you can't remove the arduino megas chip cause it is surface mount?

Wow...pretty cool.

Can you use an arduino mega without an Atmega328?

Hi, I really like the project! I just have one question about the thumb. It's clear that it's angle is different from the rest of the fingers. How did you manage to flex the thumb with the servo being perpendicular to the thumb?
Thanks!
Is there going to be much of a difference between the code for the servos & if I were to use linear actuators

How did u configured the xbees?
Archduke_1 year ago
Mind linking to the parts you used? I think I'm going to make this my summer project. I've never done anything like this though, so knowing exactly what you used would help me suss out the rest of it.
What Arduino boards are you using for this project?

Amazing! I bet you had a massive smile on your face the first time this worked!!

Very interesting project. Congratulations.
Do you think it is possible to make it less noisy gears?
