PLEN Playground - Forum

hi Wingcloud,

is it possible to copy the bleNode.py file from your plen-dev ? and send over me through email ?  i would like to check if the file is corrupted.  the python file located at /opt/ros/indigo/lib/plen .. 

thanks a lot

hi wingcloud,

i tried and can not,  it was never able to control my PLEN2Dev using PLENconnect (from andriod app).. 

does this indicate something wrong with the control board  from Edison ?  however when i use USB connection and motion editor from laptop (with server running)  it can move.

thanks
Lee

hi Wingcloud, 

i reinstall all the motion and its seem not working as well,  what will cause such issue ? GPIO is working but play motion is not working ?

in fact i run the rostopic pub command from the putty connection in the plen2Dev.  is this matter ? do i need to run from my ubuntu ROS ?
by the way i notice there is 2 connectors from the Plen head board to the arduino controller board, is the connection of the between headboard and controller board matter ?  which one i should attached to ?

thanks and really need help on this .

hi Wingcloud,

i manage to run the LED blink command smoothly now as follow:
LED ON:
laptop> rostopic pub -1 /PcToControl std_msgs/String -- "gpio,w,on"
LED OFF:
laptop> rostopic pub -1 /PcToControl std_msgs/String -- "gpio,w,off"

but when i try to play a motion to robot, its doesnt move at all,  is the command i used below correct ?
rostopic pub -1 /PcToControl std_msgs/String -- "serial,w,$pm04"

do i miss out anything in order to play the motion ?

thanks

hi Wingcloud,

i manage to get the ubuntu installed in my laptop, but when when i run "rostopic list" in my ubuntu,  the error message of "un-able to connect to master" come out.  i tried in both root and catkin directory and its failed.  i have done the env setup as proposed below:
plendev:
ROS_MASTER_URI=http://192.168.1.175:11311
ROS_IP=192.168.1.175
ROS_HOSTNAME=192.168.1.175

laptop :
ROS_MASTER_URI=http://192.168.1.175:11311
ROS_IP=192.168.1.94
ROS_HOSTNAME=192.168.1.94
...
i also tried to run the command from the Plendev using putty line :
laptop> rostopic pub -1 /I2cToControl std_msgs/String -- "gpio,w,on" 

and its works now but my plendev is kind of stuck at this LED blink ... is there a way for me to gain control back to Plendev ?
now i lost the connection to my PlenDev, IP ping doesnt seem to work now and putty connection lost to PlenDev

thanks for the great helps

hi Wingcloud,

i manage to get communication back to my PLEN2dev after reset. what i notice is when i check the environment with "env" command, i notice below response from the Edison:

with this setting, has the ROS installed successfully ? what are the next steps i need to work on in order to get my PLEN2dev to be able to run with ROS ? 

p/s: 192.168.1.175 - DHCP IP assigned by my local router through wifi.
       192.168.1.94 is - DHCP IP assigned for my laptop

thanks for the prompt response.

hi,

i am facing problem to re-connect to my PLENDEV via WIFI after i done the first two export command.

export ROS_IP=<PC_IP_ADDRESS>  -- (done)
export ROS_HOSTNAME=<PC_IP_ADDRESS> -- (done)
export ROS_MASTER_URI=http://192.168.42.1:11311 -- (not done and the PLENDEV communication stop)

i now cant connect back to my PLENDEV with the original local wifi connection through my local router.
its seem like after export command the PLENDEV LED (both eyes) are blinking on and off.

appreciate if you can help on getting me back to the robot communication.  thanks
