Roomba + Tablet PC = ? 116

ptorrone writes "Using "off the shelf parts" I have constructed another pretty good mobile robot for my home. A Tablet PC is the brain and the Roomba robot vac is the locomotion. I'm currently working on sending the IR commands from the pc to the Roomba and having the robot "do a tour" and post photos / video automatically to the "roblog" (my robot photo blog). So yah, the Tablet PC sucks ;-]"

        Why use a tablet? Maybe because he had one lying around. Seems pretty obvious to me. Anybody smart enough to put together a simple robot like this would know that a tablet PC is really overkill for this and wouldn't go and buy one specifically for the purpose. I'm sure that if he had an old laptop he wasn't using he'd have used that instead.

        because it's cool. Many "hack" projects are created not to save money, but to do something orginal, or difficult. If you want to do your "roombot" a little cheaper with an old notebook, more power to you, it might even be a better hack.

        I also doubt if he purchased the tablet with this application in mind. He probally just got "tired" of each of those toys. The Roomba, itself isn't all that practical. My Mother has one, and it doesn't suck well, is a tripping hazard when operating, and can't get dirt next to item (like couches, walls, etc.). Also, most people here seem to have little respect for the tablet as well.

    Doesn't the tablet have Wi-Fi? Why not use this as your communication medium instead? You wouldn't need to have a line of sight or even write special software (just ssh into the robot and type commands at the console ;)).

    Using a suitable video application (streaming server?) it would be possible to look through the webcam and steer around the house. The advantage of using a standard x86 tablet PC are that all of the things you need are already available, and there's very little to "work on".

    Very nice idea, though.

      For real autonomous steering you're going to need a couple of cams for stereoscopic vision, plus some badass software to handle it, of your own creation.

      stereoscopic navigation is still fairly new, even in the research world..i don't think there are any software packages out there you can go grab to work with. a quick google seems to support this since "stereoscopic robot navigation" returns mostly research papers..

      • You can do stereo vision using successive images from a single camera. Granted, this only works if the robot is working at the time, the change in camera position and orientation between images must be known. The Roomba probably doesn't have motion sensors, but there are ways to calculate view parameters using only the images - they're just very computationally complex and not necessarily deterministic.

    I'll be the first to admit I'm not an engineer or know anything about robotics, but how is this a significant robot again? I used to build RC cars/trucks and those were controlled by simple electronics which I'm sure could easily be controlled by a computer like a Palm pilot. The tablet PC is pretty cool-looking, but beyond that it doesn't seem to actually do very much. Why does the robot need a big diplay itself? Since it's on a vacuum you'd have to bend over pretty far to see anything on the screen. Or at least I would, because I'm over 6ft tall (183cm)!

    Still, it has a pretty high geek-cool factor!

      What I want to know is how is this so different from doing the same thing with Lego Mindstorms? I mean, for the price of the tablet PC and the Roomba, I can buy a lot of Mindstorms kits, and make a Lego-bot that can traverse a house... heck, Lego even had a cheap web cam with one of the kits...

      Oh wait, it can't vacuum. That must be it.

      • Better yet, for about the price of a Roomba, you can get an ER1 [evolution.com] with a camera and robotics-oriented software. An ER1 would make a much better platform for a tablet-PC based robot, since that's basically what it and its software are designed for.
    • In order to conveniently control RC servos, you need a dedicated microcontroller. They depend on control of pulse timing and/or width for control. There are kits and complete boards you can buy which provide servo control, it's easily done with a PIC for example.
      • Yeah, I was referring to those actually (The speed control for the motor and the servo control all fit into a nice little package small than any MP3 player could be). I'm sure a competent engineer could modify that thing to accept command from a Palm/iPaq/tablet/whatever. In fact, they are all radio-controlled so someone really clever could probably find a way to use 802.11a/b/g operate the thing.

        If I knew anything about physics, engineering, science, or computers, I might have given it a try!

        • Radio controlled stuff uses assorted low-frequency (much, much lower than WiFi) AM or FM (or, lately, PCM) signals. In order to use WiFi you would have to have a little computer in there to speak to the ethernet interface.
          • The key word is 'little' computer. Very little. Probably only an IC or two. They crammed a controller for various USB antennas into a Slimp3 (among other things) so I can't imagine this would be prohibitive for a Roomba sized device.
            • It's not a matter of size, it's a matter of cost. It's quite doable. However you made it sound like you wouldn't need additional hardware, and that was my only complaint. Nonetheless unless it needs to be fully autonomous it may not be necessary to store the computer on the device.

    The problem with the Roomba is that the "dirt compartment" is soooo small. So when you do get around to sucking things up, in little to no time is it full. Additionally because there is no warning, it can go on for a while, just collection, and disposing dirt elsewhere. After a while the garbage on the carpet is worse than what it started out as.

      I have a Roomba too and I've noticed the same thing -- but only when I go a while between cleanings. If I use it every couple of days, after a week or so it gets rid of enough accumulated dirt that subsequent runs don't fill up the compartment any more. If for whatever reason you can't use it that frequently, then yeah, it's probably not the right vacuum for you. I fire it up when I leave for the day, so it's no big deal to use it nearly daily.
    • I suppose if you have a lot of big physical debris this could be a problem. I think most people just have dirt, dog hair, etc...

      The directions do say to empty the compartment every time you do a room. Its hard to imagine a room with so much debris that the compartment would fill in one session. Although, I admit I did fill it once like that when it got under the x-mas tree and started sucking up all the pine needles...
