    Re: TBGL - Support not available from Petr [16.9/2010 - 18.9/2010]

    Hi guys,

    I am back. Bratislava is place of some contrasts - further from the city center it looks like in 70's or game S.T.A.L.K.E.R, but the city center is very nice.

    Paper was presented and is placed in the publication everyone attending the session got, I placed thinBasic website to references as all my images in article are TB based and the technique was coded in it as well. The same article will be published in AT&P Journal Plus magazine as well.

    Kent, the Summer Glau models are currently out of stock

    Welcome back Petr. Glad you had a nice trip in a beautiful town. Did you hear about anything incredible being worked on?

    Hi Kent,

    well, most of the presented stuff was strictly for educative purposes, so some presentations had information like "if left wheel is turning faster than right one, robot is turning right".
    Then there were some interesting mechanical solutions as well.

    But I personally liked presentation of some kind of flying robot, with 4 propellers. You can get it for around 300 EUR. It worked quite ok, just once it cut my leg. I can tell you it gives quite horror impression, when you see something making noise in the passages and even in outdoor, about 70x70 centimeters in size and moving deadly fast. It reminded me of little flying robot in Terminator: Rise of the Machines.

    Those 4 rotor craft are amazing. Here is some new video of one, able to fly though a hand tossed ring into the air, just amazing that it can do it.

    Hi Kent,

    yes it is great!
    I think what I saw live had very similar construction to this, if it wasn't this model

    hello Petr
    this is an extremely technical paper, sure not for me.
    i have an idea about service robots who provide service in restaurants or any limited area place, (if it is not already employed):
    the usual idea of the robots is that their brains are attached to them, i saw a robot picture in which the laptop attached to him, but what if the service robots brains located outside of their bodies, such as a cheap desktop with a wireless connection and running the controlling program, now the robot have a wireless receiving/sending device such as used in the small remote controled toyes.
    i think this approach are cheaper and more manageable since you can easily manage the controlling program, and commercially you can sell the robot body and the controlling program, the restaurant owner can use his own computer to control the robot, and for controlling more robots, either using a one computer for every robot or using an OS and a program suitable for running all those robots simultaneously. think of the multithreads ideas, or parallel processing and the multi core cpu.
    regards

    Hi Zak,

    thanks for your ideas!

    Your proposal is very interesting, but such a robot would not pass safety certificate here, I am afraid. Imagine there is some lag in the communication and the robot runs over a child, because he didn't manage to process the input from proximity sensors. Not speaking of fact the robot could be kidnapped by evil personTM and do damage to furniture and people.

    The choice of computer is also quite important, as most robot software designs today run in multiple threads, so it again could cause some problems when using "any computer".
    Currently, solutions like Nvidia ION ITX boards are quite cheap, and the robot parents have precise platform they can optimize for and do extensive testings whether the sensor fusion is done in time, before they let the robot move in crowded scenarios.

    Thanks for uploading the PDF Petr, I found it quite interesting.

    Were you able to take your camera to the conference & film any of the robots?

    Hi Matthew!,

    thanks! The event we attended was called "Robotics in Education", which lasted 2 days, and was followed by 2 day robot competition "Robotour".
    We sadly have to leave just after the first 2 days so I did see only few bots in the movement.

    The good news is that the people organizing the race provide enough photo material here:

    Here photo of the robot which cut my left leg by its propeler (on photo with cover, but it was flying without it as well):
