Robo-Arm Signatures Are Legal, Gov't Buys One

AndreV writes "It's endlessly comforting to know a recently designed and implemented long-distance robotic signing arm can produce signatures legal in both the US and Canada. The aptly named LongPen replicates the handwriting from a person writing in a remote location — with the unique speed, cadence and pressure of a human pen-stroke. It started as an idea from author Margaret Atwood to help free her from grueling, multi-city, multi-country book tours, but the hard stuff was done by a bunch of Canadian haptic gurus, whose design took into consideration many factors of the human arm and how we write. How it works: from the author-end, data protocols are set up, and the pen pressure is measured on a special tablet. The data streams to the robot, while algorithms smooth out all the missed points. Complex math operations were used to help the mechatronic limb repeat the hand's motions without unnecessary jerking, and programmers had to 'scale time' or 'stretch time' by breaking down the movements, essentially tricking the eyes into thinking the robot is writing fast. It was recently adopted by the Ontario Government to sign official documents. It helps criminals sign books, too."

  1. This is news? It isn't new. by pz · · Score: 5, Informative

    Robotic signature machines have been around for decades. Some of my colleagues at MIT worked on the first modern ones based on plotter technology in the late 1980s/early 1990s which were quickly bought by places like the US White House to sign letters.

    A 5-second search on Google for "signature machine" comes up with 8 thousand hits. There's an autopen entry on Wikipedia indicating that mechanical signature machines have been around since the early 1800s (yes 1800s), and lists three current manufacturers of the devices.

    So, this is news? Just because someone hooked up the recording part and the writing part across an internet connection and made them work in real time? That makes it to the front page? Is that really the first time it was ever done? Lots of other things have been done telerobotically already.

    If you search for LongPen videos on youtube you can see a demo of this at a trade show...

    It's more than just a remote signature product - it's really meant for legal/financial use where there may possibly be disputes over what was signed, who was present. etc.

    What the product does is transmit a photo of the document in the robo-pen device to the remote signing end where it appears in a display built into to the tablet device you sign on - it's as if you're singing the real document on the appropriate line/whereever. The system also takes and stores before/after photos of the signed document and saves audio/video of the remote signer (& robot end?) so that these can be brought up if there's any legal challenge... It should be noted that the anticipated legal challenges arn't because of this being a remote signature device, but rather that the whole photo/audio/video capture system is designed to address the challenges that already occur with traditional signed documents.

    There are various comments in reply to this article about how this is nothing new, but from the video it seems that not only is it an entire singing/verification system, but also the signature reproduction quality is very high - it detects/reproduces 60 different pressure levels and samples at 2000/samples sec.
