- Clone
https://github.com/m-elwin/me495_urdf.git
- See how the robot moves in rviz.
- Change the launchfile so it no longer loads the
rviz configuration.
- Then, when rviz loads, set it up to see the robot.
- Rename
slidebot.urdf to slidebot.urdf.xacro (mv slidebot.urdf slidebot.urdf.xacro)
- Modify it so that it is a valid xacro file (adding
xmlns:xacro="http://wiki.ros.org/wiki/xacro" to the robot tag)
- Create a parameter called
base_radius and use it as the radius of the base sphere
- Declare this parameter directly as a
xacro:property
- Make the length of the arm 10 times the radius of the
base sphere using a formula in xacro
- Using the information here xacro YAML
load the
base_radius from a yaml file instead of declaring it directly in the xacro file.
- Use a
xacro:macro to add a link to the arm that is the same as the
current arm link but on the opposite side of the body
