Check the baudrate that is being used for robotis_params. Try 1000000.

Hi, I had the same issue which was solved by setting use real robot to true in the tracker_params.yml file. pi_tracker/params/tracker_params.yml

Hope it helps.

Yes it is! Thanks again!

2013-03-10 12:53:22 -0500 asked a question robotis.launch How to define motor parameters?

Hello,

While working with pi_tracker I have been trying to get some Bioloid Dynamixel ax-12a motors to move with kinect input. I have managed to get input to to move the motors and am now wondering where I can define motor/joint ID's for the robotis.launch parameters.

I am unsure as to whether I am supposed to edit the dynamixel parameters(pi_tracker/params/dynamixels_params.yaml) or add to the robotis parameters(pi_tracker/params/robotis_params.yaml). Or is there another way to define my motor setup so that the proper motor moves?

Thank you for your time.

2013-03-09 15:47:04 -0500 asked a question robotis.launch trouble finding dynamixel motors

Hello,

I am attempting to run pi_tracker and after attempting to use "roslaunch pi_tracker robotis.launch" I encounter an error where none of the motors are detected.

I have detected the motors using the dynamixel_motor package and can successfully detect and identify motors.

Currently I am only connecting 1 motor(id 1). The usb2dynamixel is currently set to TTL and I have attempted multiple usb ports/cables.

Am I missing a python library/dependency of some sort?

Thank you for your time. -zab

Up and running, thank you very much! I am attempting to control a bioloid with this package.

2013-03-09 12:01:53 -0500 commented answer Rosmake pi_tracker error, needs nite

I have the openni/nite drivers/headers in /usr/include/ni and /usr/include/nite

I don't understand why pi_tracker can't seem to find them.

Deleted and redownloaded pi_tracker, nite is still listed in the manifest.xml Here is the rep where I am getting it from: svn http://pi-robot-ros-pkg.googlecode.com/svn/trunk/pi_tracker

I ran the commands but I still get an error that says nite is a dependency. Is this normal?

Hello,

While attempting to use "rosmake pi_tracker" I get an error saying that I need to have nite on the system to compile pi_tracker. After a quick search of the wiki it seems that nite is no longer in the works. How can I compile pi_tracker without the nite package? Is there a workaround for this as I would not like to uninstall the working packages/drivers.

Installed:

openni drivers (openni-bin-dev-linux-x64-v1.5.4.0)

nite (nite-bin-dev-linux-x64-v1.5.2.21

I can run openni_launch and openni_tracker with rviz and get input as well as run the sample programs that come with the drivers/middleware. Thank you for your time.
