Khepera IV / Questions regarding the makefile in libkhepera

« Last post by michael5511b on August 07, 2019, 11:01:47 PM »

Hello to all,

This may be a very basic question, but does anyone know how to modify the "makefile" text file in libkhepera-2.1/template, so that I can make c files with names other than "prog-template" and create make files with names other than "template"? Also, is there a way to make multiple c scripts at once?

I have been working with khepera IV a few months by now, but I always edit everything in prog-template because I am afraid to mess up anything in the "makefile" text file. I would rally appreciate the help, thanks!

Khepera IV / Frequency of sending data to server using TCP

« Last post by groverjaskaran@gmail.com on July 24, 2019, 06:48:21 PM »

Hi, I am wondering if anyone knows how to send data from IMUs and Encoders at a stable frequency to the server. I am using a socket client approach to talk to the robot over WiFi.

Khepera IV / Problems with Socket Communication (Khepera as Client and Computer as Server)

« Last post by michael5511b on July 19, 2019, 12:28:11 AM »

Hello to all,

I have successfully established socket communication (TCP/IP) between the Khepera 4 and my computer, now I am able to send and receive information between them. However, I found out that the communication rate is not stable, and I am not able to send or receive data at a constant rate, and the communication frequency varies from 5Hz to 300Hz during a single test run. Without constant communication rate, any robot control algorithm that is a function of time implemented from my computer and sent to the khepera will end up with poor performance. Does anyone have suggestions for this?

Please advice. Thank you!

Khepera IV / Re: Problems connecting the khepera IV to a wifi network.

Hi,

you have to adapt the ESSID name and IP address to your network. This file is edited as an example with a Wifi called Korebot.
For example, if your Wifi is named "HomeWifi", you have to change "korebot" to "HomeWifi" and change the IP address too (you have certainly a range of 192.168.1.1 to 192.168.1.1).

Best regards

Khepera IV / Problems connecting the khepera IV to a wifi network.

Hi,
I am having issues activating the wifi of the robot. I followed the instruction in the Khepera IV User Manual 4.0, section 9.2.1.
First, I have opened the file in /etc/wpa_supplicant/wpa_supplicant-wlan0.conf and i found the file already configured with a wireless network named korebot without encryption. So i didn't change it.
After that i have configured the interface file in /etc/network/interfaces as following:

auto wlan0
#iface wlan0 inect dhcp
iface wlan0 inet static
wireless_mode managed
wireless_essid korebot
address 172.16.156.57
netmask 255.255.255.0
gateway 172.16.156.1

the address being the static robot ip i found in the robot (i didn't change it either)
the gateway is the ip address i have used for my pc.

for the wifi network i configured ad-hoc network with the name korebot with the Network Manager of Ubuntu 14.04.

finally i have rebooted the robot and the pc.

However, after all that, the robot was not connected, and if I use the command ping i get the message that the address is unreachable.

Please advice. Thank you.

Hi,

If your robots do not show any response to your OHC or they look dead, you have to flash them.
