I've been looking for software like this for some time. Can you tell us a bit more about the software development plans? Do you see it continuing? What are the requirements for the exe file? I tried running in under WINE in Linux, but it doesn't work, so I wondered if I was missing some dependencies? Can it be built for Linux or Mac? Any instructions? I didn't see any in the source code? BTW <a href="http://actuatedcharacter.org/" target="_blank">http://actuatedcharacter.org/</a> doesn't seem to be working at present, but the blog is functioning.

It appears to define the controller type,not an instance. It is not clear how you want to use multiple MRC3024. Is it that you have more servos than 24 ? There is no inherant support in the MRC3024 firmware for multiple controllers.

I was curious about the possibility of using two MRC3024. From the manual I read: '$ DEVICE Sets the controller applicable to the program. sentence structure '$DEVICE [Controller] where should I put this command in the structure? For example if I want to say to the first MRC. main: Read the pin ad0 move the actuator XX ........... ................ and then I want to jump to the second controller and said: move the actuator YY and returns to the main but above all, as is done downloading the code? Can you give some examples? Even very simple. I just want to understand the mechanism. Best regards.

Most people like robots but they are price somewhere between $800-$2000. Hobbist robotics are therefore not widespread in most of countries due to the high price tag. By offering robots at $150 and with the sex appeal of smartphones I am hoping this will create a new robot market that does not exist.

This is where the AVR Code is stored. 2) Additionally there is an EEPROM module inside that can be addressed by the processor. However code can't be loaded into the EEPROM (but I guess you alreayd know this). If your code is too big you may be able to store static info such as Motion Data on the EEPROM though and then read it back during the execution of the program. You haven't shared much details about your code (ie are you suing the Robobuilder C code, your own custom one, ...) but there may also be some bug in code that's causing execution to halt. Pedro.

Although they work, they seem to supply excessive voltage to the motors: the KHR stock battery is 10.8V where a fully charged LiPo is 12.4V. From our experience what we've seen is that servos tend to get damaged faster (ie blown mosfets usually). If you're the hacker type, you can try getting 9x 1.2V AA rechargeable NiMH batteries and building your own battery pack probably reusing part of the damaged one you have. There 1.2V AAs that have higher capacity than the stock ones that come with the KHR. Make sure to proceed with caution - and at your own risk! - if using this approach! With regards to using a LiPo, if you choose to go down this road, we would strongly recommend getting a voltage regulator. It is quite hard to find one that can provide either 10.5V or 10.8V. The largest variety can be found with the "BEC" denomination (they're for the RC world) but they're typically for 5V, 6V or 12V (some also offer 8.2V). The only regulator we found capable of doing 10.8V was the Castle Creations BEC Pro. The BEC Pro does have a few things to it: you need to get the programmer in addition to the Regulator to set the desired voltage and it has a bit of size. As a side note (and this is unconfirmed) we've read some rumours it causing brownouts but this is unconfirmed. (the concept of brownout is a bit exquisite but I'm sure wikipedia or google can explain it). We haven't tried the BEC Pro ourselves but maybe with a bit of research you may find similar regulators (or BECs) that can output the steady 10.8V. FIY using a regulator also improves the robot's performance as the performance remains constant: ie it always gets the same voltage regardless of the battery level meaning torque is constant.

The stock battery that comes with the robot is only 1 000mAh (the same as a Bioloid PREMIUM) but on DARwIn it's powering way more equipment: more servos, more hardware including a FitPC2i and camera) making it's run time about 10 minutes from our experiments. The cavity for the battery has also got plenty of room to accommodate a much larger LiPo. Therefore, we were able to source a higher capacity LiPo (1 550mAh) and the appropriate connectors. 1 550mAh is not yet the ideal for such a large robot but it's a good improvement over the standard battery (1.5x more power). The other advantage is that this battery offers much higher discharge rates (20C which, on a 1 550mAH battery means 3.1Amps triple what the standard battery can offer) The battery as well as the necessary adapter can be found bellow: <img src="http://robosavvy.com/store/images/R1550-3S-20.jpg" border="0" /> <a href="http://robosavvy.com/store/product_info.php/products_id/1974" target="_blank">http://robosavvy.com/store/product_info.php/products_id/1974</a> Adapter to XT 60 (the connector used by DARwIn): <img src="http://robosavvy.com/store/images/14543.jpg.thumb_150x110.jpg" border="0" /> <a href="http://robosavvy.com/store/product_info.php/products_id/1973" target="_blank">http://robosavvy.com/store/product_info.php/products_id/1973</a> Regards Pedro.

It offers a very neat (graphical) way to set up all the interfaces including WAN connection as client to a home network. It also offers a Graphical view to opkg and HDD usage. (Luci should be available by pointing your web browser to the board's IP address). The latest batch we got from Omnima should have come preloaded with this but in any case users can download and flash the image themselves. The image was built specifically for the Linuxified project so it includes the necessary kernel subcomponents to install UVC (not sure if it's pre installed already) as well as mjpeg streamer and python. It also includes the latest Luci which offers that Graphical configuration interface (I believe you just need to connect tot he board over Ethernet and open the board's IP on your browser). The only bit I don't recall is if you need to set your LAN to a static IP address (and which) or if it will automatically assign one. (I think you need to set your PC manually to 192.168.1.40 for example and then try <a href="http://192.168.1.1" target="_blank">http://192.168.1.1</a> or 192.168.1.254). -- let us know how this goes! As a side note, we've 3D printed a box to send you and also included a wCk cable already soldered to the Voltage Regulator and witha DC barrel jack on the other so you can power the omnima directly from any connector on the wCK bus. (we should be shipping it to you in a couple of days as this is in the Lab not the WH) We've made another set for ourselves and I'll post some pictures tomorrow about this. It's a very neat approach for Power Supply. no hassle with batteries or anything; you can even hotplug and unplug the Wall Adapter if the battery is low and the Omnima will just keep running.

The 6 Servo packs from Robotis offer excellent value for money allowing you to get 6 servos for approximately the price of 5 (ie you get 1 free). The AX-18A Pack of 6 is particularly interesting for Bioloid owners as it offers a more affordable way to upgrade the Leg servos to faster ones. <a href="http://robosavvy.com/store/advanced_search_result.php?keywords=ax-18" target="_blank" class="postlink"><img src="http://robosavvy.com/store/images/AX-18-pack6.jpg" border="0" /></a> The benefits of this upgrade will depend on your application but from what we see on the Bioloid GP (that uses them in the legs on a 16 DoF configuration), the robot walks and reacts much, much faster.

I'm quite new in robotic I'm use this usb module for connecting the RM-G144 to pc <a href="http://www.robot-electronics.co.uk/htm/usb_i2c_tech.htm" target="_blank">http://www.robot-electronics.co.uk/htm/usb_i2c_tech.htm</a> thanks Roboard - x86 Embedded Robot Board http://robosavvy.com/forum/posting.php?mode=reply&t=7745 alib022, in Roboard - x86 Embedded Robot Board Mon, 30 Jan 2012 11:43:19 GMT http://robosavvy.com/forum/viewtopic.php?p=33565#33565 RE: Maximum actuators per CM-510? (current limit) http://robosavvy.com/forum/viewtopic.php?p=33562#33562 As you no doubt know the CM510 has a 10 amp fuse, this is inline with the lipo battery in the normal mode of opertion/connection. So its going to stop the lipo bursting into flames or the robot wiring melting in the event of a short. There is no reason why you can't apply the lipo voltage directly to the bus. The CM520 is not then acting as an on/off switch or a circuit protection device. Current is then what your lipo can give, or of course what the wiring bus can stand. I would strongly advise that you still put some fuse protection in place but no need to worry about an overload affecting the CM510 Bioloid & Robotis http://robosavvy.com/forum/posting.php?mode=reply&t=7740 Dewey, in Bioloid & Robotis Sun, 29 Jan 2012 18:17:19 GMT http://robosavvy.com/forum/viewtopic.php?p=33562#33562
