So I have always been interested in robotics, and it just so happens that I finally have both the time and money for a summer project this year. Something basic would be great, but the diy kits don't really appeal to me. I'm fairly confident with my mechanical skills, but I have no programming experience whatsoever. I think I would like to build some sort of pan and tilt turret that I could run from my computer using a usb cable. Not too interested in sensors for this project, just want to learn a little about servo control and some of the other hardware. I found the pan and tilt kit in the garage sale section (the one with the phidgets usb servo controller), but I'm not even sure if that's what I would need for this project. Any advice is much appreciated. On the other hand, If this is too complicated for a first time project, please tell me. Thanks in advance!
I have been a lurker on this forum for quite some time (BTW, you guys are incredible) and I have decided to track my progress on my latest project here. I had been posting in my blog, but have come to realize this area (the project shocase) is a far more appropriate place.
I am building a pheonix/micromagic inspired hexapod that will primarily be a testbed for different computer vision and AI concepts I am working on. My goal is to make him as autonomous and aware of his environment as possible. My senior project consisted of a camera on a lynxmotion pan-tilt rig controlled by a phidget advanced servocontroller which tracked peoples faces using OpenCV. This uploaded data to a webserver about what it viewed. So my first goal with Ally is to use the core of that project as the foundation for this one. My parts list as of now:
6 HS 225MG
8 HS 485HB
6 HS 645MG
(all servo choices are subject to change... [Read More]
I am new to this board and googled the whole day long to find some answers: no sucsess till now:
I have some serious prolems with the usb2dynamixel converter: I want to control a robot arm via PC using Windows7 and a usb2dynamixel converter and 13 AX12+ Dynamixels. Everything went fine until yersterday: My first machine is a Windows Vista based 32bit system, where I developed my software and tested the Dynamixel Configurator, so far, so good. Yesterday I tried two different Systems ( Win7 on my Laptop and Server 2008 on a different machine) On both machines I get major connection problems: When I look at the LED (RX) on the usb2dynamixel converter ist is flashing wild and does not stop sending data to the PC: so the whole system gets unstable and I can not connect to the TTL DynNet. On the Vista machine, there is not such behaviour, but since yesterday I have the Problem that from Time to time the Vista machine just reboots without any... [Read More]
Okay, Looking for a Room mate for Robo Games 2010. Dates I'll be in town are 4/22/10 -- 4/26/10.. My wife isn't coming this year.. and looking to reduce cost as much as possible. Anyone interested, please PM me.
anyone know how to start to build our own basic atom pro 28 carrier board ??
without using Bot-board ll
i owned a bot-board ll
but i wanna learn more... anyone can help me??? please
i need to build my own carrier board for Basic atom pro 28... thanks...
I'm having a lot of trouble getting x-ctu to communicate with my xbee pro (series 2). Here is how I've gotten to where I am now*:
1. Downloaded and installed CDM20600.exe from FTDI to make my USB port recognizable as COM4.
2. Downloaded and installed 40002637_c.exe from Digi, the x-ctu application for the xbee.
3. Inserted xbee into the xbee explorer and connected the usb to the PC.
- I note that the PWR led is on, as is the ACT light. They are constantly on. Tx/Rx flashed 3 times with the PWR led immediately after the usb was plugged in and has remained off since.
4. Ran X-CTU, selected USB Serial Port (COM4) from the com port setup list. I did not change the defaults as the devices have not previously been configured.
5. Click Test/Query button and the Tx/Rx light on the XBee Explorer flashes once. The X-CTU application informs me "Unable to communicate with modem."
-Trying to get it to work by clicking things, with the Enable API... [Read More]
Having read extensively through the forums, I suppose I'll share...
I recently invested a decent amount of time overhauling my lab's open-source software for controlling Robotis RX-28 and RX-64 servos from a PC. The code is written entirely in Python and is thread-safe, so that multiple servo objects can be controlled / queried "simultaneously" on the same USB2Dynamixel bus (within the same process). The library should function on Linux, Mac, and Windows (yay, python!), and the only dependency is PySerial for communications. ROS (Robot Operating System) support has also been created.
Over in the humanoids forum I've been blathering on about testing the Turnigy/MKS HV-300 servo. It makes much more sense for me to post over here in actuators.
I'm most interested is seeing the relationship between the various types of torque ( dynamic, stall, and holding. ) I'm especially interested in seeing the dynamic torque on this particular servo as I know the dynamic torque of the AX-12 has been reported to be less than half its stall torque.
If anyone has suggestions or ideas on the best way to go about this I would love to talk about it. Once I have the method worked out I'll test out some other servos as well.
Also.. If anyone has any data on big boy servos such as the RX-64 ( or anything else ) I'd definitely... [Read More]
i read the manual and i have three questions
1.- how many DC motors and how can I conect it to arbotiX(beacuse are two encoders but to many pins)
2.- can i use CMUCam2+ on arbotiX, and if is can how can i conect it them
3.- why dont you use CMUCam2+

My new baby. I put robots on hold. I know I just said that. But it was worth it.
