Khepera IV / Re: Installing Robot Operating System (ROS) on khepera IV
« Last post by williamdwarke on August 30, 2018, 05:33:03 PM »
Any luck with this? I was investigating the same thing and came to the conclusion that it would be more pain than it’s worth. Instead I’m writing a TCP communication client node and using each khepera as a server running its own standalone C++ program.

Kilobot / Re: Kilobots not responding to OHC
« Last post by kteam on June 19, 2018, 08:14:23 AM »
Hi,

if the Robot didn't respond even after an firmware install means that the IR calibration has been erased (during update) or is not more correct.
in Both case, the only solution is to send back the robot to K-team for calibration.

Best regards

Kilobot / Real Time coding of kilobots from eclipse and matlab
« Last post by pradyum2104 on May 31, 2018, 07:03:51 PM »
I want to use the real time data of Matlab variables in Eclipse and want to generate the hex file from eclipse so as to burn it to the kilobots. Is there a way to send real time data from Matlab variables to eclipse environment?  and also is there a possibility to code kilobots with hex files from eclipse instead of using the kilogui application?

Kilobot / Kilobots not responding to OHC
« Last post by Amaya on February 27, 2018, 03:55:04 PM »
Hi,

I am actually working with Kilobots on Debian. I have followed the instructions here : https://www.kilobotics.com/documentation.
Some kilobots work perfectly, while others do not repond at all to the OHC (when I use the kiloGUI interface), even though I have correctly updated the firmware on these kilobots, and they are turned on (green light flashing).
Is there any explanation for this issue? What should I do?

Thanks.

Khepera IV / ssh connection- response too slow
« Last post by Firhanh on November 11, 2017, 02:31:16 AM »
Hi,

I'm able to connect my PC to khepera IV via ssh connection, the problem is the connection response is too slow..
 
I've tried to ping khepera IV IP adress from my PC and the result is shown below

Firhan@Hz:~$ ping 10.42.0.134

The ping is too high

but when I tried to ping my PC from khepera IV the response is great

Khepera IV / Installing Robot Operating System (ROS) on khepera IV
« Last post by Firhanh on November 08, 2017, 08:37:07 AM »
Hi,

I want to install ROS in Khepera IV to make it easier to communicate with my PC.
The problem is I don't know if ROS is compatible with Khepera IV or not.
Does anyone have experience in doing this? Is it possible to install ROS on Khepera IV?

I'm looking for advice..
Thank you.

Kilobot / Re: OHC Resetting
« Last post by kteam on June 01, 2017, 08:30:40 AM »
Have you tried to reflash the OHC using AVRstudio? Normally it solve the problem of corrupted Flash.

But, in your case, if the device manager did not find the AVRispII on the OHC, you won't be able to reflash it.

Try again with AVRstudio, if it doesn't solve the problem, please contact K-Team and return the OHC for repair.

Best regards

Kilobot / Re: OHC Resetting
« Last post by Dasto on May 31, 2017, 02:22:57 PM »

The drivers were installed and working, in fact I was able to flash the OHC successfully. Only after the failure to flash the Kilobot did it start to behave this way, and no changes were made to Windows. It was literally a few seconds between unplugging the OHC to plugging it in again.

I tried a new Win7 machine as per your instructions, however as the OHC is in some weird mode, so it is not possible to connect to it as per step 2.

As soon as I plug in the OHC, the lights appear as in my video. The 2 read lights are permanently on, and the green ones flashing. Device Manger is refreshing every 4 seconds. Usually when Device Manager refreshes it's because it detects a new device. In this case, as it refreshes every 4 seconds, it detects the OHC then loses it, detects it, loses it etc. so I presume the OHC is restarting.

What else can I try?
