Installation on Linux #71

Closed greftly closed 1 year ago

greftly commented 4 years ago

Hi,

I installed Klampt with following Klamp't Tutorial: Installation on Linux. I'm getting error when I run python kbdrive.py ../../data/tx90roll.xml.

(base) task@task:~/Klampt/Klampt-examples/Python3/demos$ python kbdrive.py ../../data/tx90roll.xml klampt.vis: using Qt5 as the visualization backend kbdrive.py: This example demonstrates how to drive a robot using keyboard input RobParser: Reading robot file ../../data/robots/tx90pr2.rob... RobParser: Invalid robot property servoI on line 27 XmlParser: XmlRobot: error loading from file . XmlParser: XmlWorld: Unable to load robot tx90pr2 Error opening or parsing world file ../../data/tx90roll.xml Traceback (most recent call last): File "kbdrive.py", line 118, in raise RuntimeError("Unable to load model "+fn) RuntimeError: Unable to load model ../../data/tx90roll.xml

How Can I fix this? Thank you.

The line "RobParser: Invalid property servoI on line 27" is very odd. It should be internally converting the property name "servoI" into lowercase "servoi", but it doesn't seem to be doing that properly. Do you have an atypical system setup? What system are you compiling under?

You could try going into the file "Klampt-examples/data/robots/tx90pr2.rob" and rewrite "servoI" as "servoi" on line 27 to see if that fixes the problem.

Thank you. It works well now. But all of .rob files written as "servoI". I'm using Ubuntu 18.04.4 Regards.
