You guys are awesome.. #1

Open Arvrairobo opened 5 years ago

Arvrairobo commented 5 years ago

Guys you have made a very super advanced prosthesis hand and love you for that, keep it up.

i do have few questions :

1) how create PCB and i dont find its driver code, would you be able to upload driver code for PCB? how PCB will work without the firmware? i do only see EAGLE schematics. same for EMG and hand control PCB

2) is this project still in development? is it still in beta or now no more development is happening? cause i dont see any new development since 2 years

3) i really want to make such a prosthesis hand but still there are some pieces missing on instructables they are mostly in the assembly part..

4) do i have to make those PCB myself or is there any company which can provide me this in cheap cost?

please please let me know

Thank you very much

  1. You can find links to all the code here: http://bretl.csl.illinois.edu/prosthetics Scroll down to "A LOW-COST, OPEN-SOURCE, COMPLIANT HAND FOR ENABLING SENSORIMOTOR CONTROL FOR PEOPLE WITH TRANSRADIAL AMPUTATIONS"

  2. Development has been happening on our commercial version of the hand.

  3. Check the links in #1 and you I think you should have all the parts you need.

  4. We typically purchase PCBs through PCBWay and JLCPCB and then solder them by hand when we get them.

Could you please provide GERBER files for all the PCB's, if you could that would be great..

Thanks

Arvrairobo commented 5 years ago

also i do see there are other PCBs too like electrotactiles and others which are not written in that instructables guide, do we need those PCB as well? also how to connect the circuit with each other, is there any diagram for the same?

DOUBLExA commented 5 years ago

The gerbers you generate are dependent on the board house you use to manufacture the board. For this reason, we supplied the raw PCB and schematic files, which is much more useful. If you go to the website of the company you want to use, there are instructions on how to generate the gerbers from the pcb file. It's fairly straightforward.

Depending on how you want the user to control the hand you can use the other PCBs. For moving the fingers though, the only PCB you need the hand board. The PCBs for the other peripherals like the pressure sensor and EMG board communicate to it via I2C. Our EMG board was designed to take in 2-8 EMG channels and is programmed to use pattern recognition. You can use other methods of control though like force sensitive resistors or 2 EMG channels for direct control, but you'd have to make or get the hardware for it and communicate via I2C to the hand board.

==> but if only handboard PCB then how EMG signal will pass signal to handboard PCB, we need EMG PCB so that it passes the signal to handboard PCB?

it is looking so good on the instructables and on the video, why you have still not launched in the market? is it not commercially viable?

i am from india and i have very good contacts if you guys wants to partnership with me and i would be happy to open the door for both us, do let me know if you are interested in this proposal and we can discuss more?

Arvrairobo commented 5 years ago

I think the only thing missing on the instructables are

connection diagram of different PCBs/Circuits with each other, would you be able to share it?

Many thanks

Ocanath commented 5 years ago

As you noticed, we haven't updated this project in a while, and most of the engineers who worked on the open source version of this project have since moved on or are working full time for the company. As such, we can't dedicate any more resources to further documenting this project. However, it is sufficiently documented; in particular, the electrical connections you refer to should be self explanatory based on the net labels in the pcb and schematic files. We use I2C, a standard communication protocol between systems. This paper may also help: https://static1.squarespace.com/static/53d016d6e4b0e86a1a65f38a/t/584c45ebe58c620f9605110b/1481393831428/Akhtar2016.pdf .

alright thank you very much for the great project, but i am sorry to hear that no more progress has been done on it after 2016, but i would like to take on this project further because it will be really useful for lot of people who are suffering from amputation in developing nation like india. my aim is to offer this high end hand in very low cost so all of them have it.

now i am starting to build this hand and i will let you know the progress on this thread, also while developing, i may have lots of other questions, so i will ask them here, i hope you guys will help me

also if it is not convenient here to discuss, i may drop emails to you, if that is okay for you

thank you very much for the great work.

Arvrairobo commented 5 years ago

@Ocanath so i have trying to 3d print the STL files that i got from the website and instructables, but it is very difficult to print some part of the hand which requires to add "support" during printing "which is what 3d printing guy informed me" so he said to ask if you guys have original files with support or 3d files from which you generated this STL files, if you provide me those files that would be great or show me a direction so that i can successfully 3d print, please :(

Arvrairobo commented 5 years ago

something like 3d models or source files for models

Arvrairobo commented 5 years ago

@DOUBLExA @Ocanath please help me with the above things, i am not able to print it without them or please suggest me a way.

ZGMF-X20AR commented 4 years ago

@Arvrairobo Have you figure out how to connect the EMG PCB with the Hand PCB? as I'm facing the same problem.

Arvrairobo commented 4 years ago

@ZGMF-X20AR sorry no luck yet and i was busy with other project to be honest so didnt worked on it after that, but i am now free and focusing again on this project so, i will get back to you if any success on the same,

so how much you figured out in this project? do let me know, may be we can help each other

ZGMF-X20AR commented 4 years ago

@Arvrairobo thanks for your quick response, currently I'm still waiting for other components to arrive. Back to your question, I was thinking to connect the EMG MCU with the Hand MCU via SDA/SCL of both MCU.
