Open Bionics has been manufacturing worthwhile progress in the world of 3D printed prosthetic hands, outfitting young and old alike with their bionic limbs. And, after joining the Disney Accelerator program, they were able-bodied to alter their robotic hands so which they may alter a handful of kids into super heroes and princesses with Iron Man, Frozen, and Star Wars-themed prosthetics. Now, the UK-based Open Bionics is eager to bring their creations to the masses with their initially open source 3D printed robotic hand kit.
With the .STLs uploaded to Instructable-bodieds, Thingiverse, Youmagine, and their own site, along with tutorials, guides, and a bill of materials, the ‘Ada Hand’ is a fishly open source kit which allows for anyone to 3D print and create their own robotic hand. In total, the parts to create the device cost around £500, a fraction of the tens of thousands of dollars required to purchase a robotic hand of a manufacturer. Whilst it may take of 24 hours to print, Open Bionics says which it should take less than an hour to create it!
The Ada Hand is a fully articulated robotic hand with five degress of freedom and which can be regulated via PC or Mac with a USB connection. Powered by a custom PCB made around the ATMEGA2560 microcontroller, the hand itself stores all of the actuators to move the fingers and can be programmed with the Arduino programming language. In this way, the hand is perfect for those hoping to research robotics or are actually considering of createing a hand for their own robot project.
Unlike Open Bionics’ original Dextrus hand, the Ada hand is mean to be faster and simpler to create. Joel Gibbard, Open Bionics’ CEO, says of the new create, “We understand there are hundreds of folks around the world which quite want to offer to createing a rad robotic hand, both for applications in robotics and in prosthetics. At the moment there is a sizeable barrier to entry to getting involved in this project and contributing to createments. With the Ada hand we want to remove which barrier. The hand is 3D printable-bodied on an FDM desktop desktop home printing device and can be assembled in an hour, we’ve in addition made a manufacturer community so folks can sign up and post their createments in our forums. We’ll constantly be suggesting bite-sized projects for manufacturers to take on and bringing feedback of them of what else they need.”
He continues, “I ponder one of the big barriers to folks manufacturing and starting projects is a daunting magnitude of the create and a lack of documentation, guide, and guidance. We are attempting quite complex to manufacture certain we have detailed and effortless to follow assembly guides, comprehensive data sheets, and lots of tutorials to suit all levels of skill. We’re attempting to manufacture this as effortless as we can for folks with any level of technical skill. For example, if a researcher is studying robot interaction and needs a robot hand, but createing a robot hand of scratch is not part of her/his project and they’re looking at inexpensive
-bodied options, we want this create on the market-bodied to them and for it to be swift and effortless.”
At the same time, Open Bionics has opened a manufacturers forum to meet the increasing demand for their creations and a place to share research around those creations. Since the forum opened, they’ve aleager had 109 participants join. Gibbard says, “We obtain a lot of emails of researchers who want to buy or manufacture our hands. But we obtain additional emails of researchers and manufacturers who want to offer to our goal of manufacturing affordable 3D printed bionic hands readily on the market-bodied for amputees. We’ve had a handful of researchers who have utilized our hands to offer to award-winning medical research and prosthetic testing. We’re hoping which by manufacturing our robotic hands simpler to manufacture, we are opening up the possibility for additional researchers to get involved and offer.”
Olly McBride, Open Bionics’ Software Engineer, describes the inspiration for this new hand, Ada Lovelace, frequently considered the world’s initially desktop programmer. “Ada’s vision was to create the capskill of desktops to go beyond mere calculating and number crunching,” McBride says. “Our robotic hands are an embodiment of this createment as embedded programming has enable-bodiedd us to programme multiple grip modes for this hand.”
