Comments for Shinsel Robots http://www.dshinsel.com Hobby robots built by Dave Shinsel Wed, 15 Feb 2012 05:04:32 +0000 hourly 1 http://wordpress.org/?v=3.3.1 Comment on Loki Electronics by dshinsel http://www.dshinsel.com/loki-electronics/#comment-166 dshinsel Wed, 15 Feb 2012 05:04:32 +0000 http://www.dshinsel.com/?page_id=89#comment-166 Hi Robert, The Kinect sensor code creates an XYZ point cloud of everything it sees. the function "FindObjectsOnFloor" uses this data to identify objects of interest. Then in ArmControl.h" there is a function called "CalculateArmMoveToXYZ". For pure vision (which I don't rely upon as much, since I added the Kinect), the camera can be pointed with the function in HeadControl.h called "LookAtXYZ". The Behavioral module Calls these functions to guide the arm to pick up the object. Note that XYZ maps as follows: Y= distance in front of robot's front bumper. Z= height above ground, X=distance Right/Left of centerline (Left is negative). Hope this helps! Hi Robert,

I was wondering if you could share how you were able to coordinate LOKI's arm/hand location with the vision system? Great job with LOKI.

We’re currently in the midst of casting characters for the series, and have been reaching out to individuals like you in an effort to build a Dream Team of Makers. Without belabouring the details, the series will revolve around our team of Makers facing off against other groups in maker-related competitions. Competitions like: -Modifying a lawnmower into a 70mph drag racer -Designing catapults to hurl pumpkins across football fields -Constructing Rube Goldberg machines -Building human-powered submarines Our goal is to find multifaceted individuals with aptitude in numerous fields pertinent to these sorts of projects. People with experience in things like engineering, electronics, physics, welding, pyrotechnics, construction, engines and industrial design—these are the sorts we’re looking to get in touch with. Is the sort of thing that might interest you? If not, would you be willing to pass the word on to anyone you think would be right for the show? Thank you for your time, and keep up the fantastic work! Dear Steven,

Regarding the hardware, you can compare the schematic above to the one provide for the TurtleBot at http://turtlebot.com/build/ Also, I think I am going to "take the plunge" and try out ROS on my Turtle Bot, so I probably won't be adding much more functionality to this code for Turtle (but will keep enhancing it for Loki).

Unfortunately, I don't have the Express version, so I don't know why it would not find stdafx.h (that's a pretty standard header file). This is an MFC project, if that helps. Regarding hardware, yes, I used the same ports on the iRobot as TurtleBot does. (there's only 3 to pick from). I am not using the accelerometer at this point. Regarding building you a binary, I'd be glad to do that but it would not help. It would fail when it can't find the needed .dll files. So, I think you need help from someone that knows Visual Studio well, and can help with the dependencies. I have updated the download page to make this more clear. Sorry I can't be more help! Hi Mel,

Or can it be a notebook, Create, Power/I/o board for the Kinect including the Gyro like an original Turtlebot? If you have any more schematics or pix on the turtlebot. I have a turtlebot and before I install ROS, etc. I would like to try your program under windows7. thanks again. Mel hey Dave,
