2017-02-24 03:52:09 -0500 | commented answer | Find coordinates of point in a different coordinate frame However, for points without stamps, how does one know the operating frame? My point doesn't have any stamp, but I'm sure it is defined in the /world. However, when I perform Inverse kinematics on my KDL chain to that point, my IK_solver seems to take the endeff to the point in the chain_root_frame |

2017-02-23 22:34:56 -0500 | answered a question | Find coordinates of point in a different coordinate frame @2ROS0: "(I don't want to do that for some smaller tasks)" Exactly the same with me. I am looking for an API programming language equivalent of I'm also trying to see how this command works: but I don't see an indication for the current/reference frame which is not too good. |
2017-02-23 22:28:40 -0500 | commented answer | Find coordinates of point in a different coordinate frame @roso I have the exact problem. It seems like people don't answer questions here anymore. Just my observation. |

2017-01-31 06:51:11 -0500 | asked a question | KDL::Chain from KDL::Tree? 1) Is it possible to construct/create a KDL::Chain from a KDL::Tree since trees inherently contain chains? I intend to construct a kdl tree using the kdl_parser on the parameter "robot_description", and then extract my chain from the resulting tree. 2) Is there a way to construct a kdl chain or tree from a move_group (perhaps using a parser)? 3) Is it possible to construct a kdl chain from an object of the class robot_model::JointModel? and can a kdl tree be derived from an object of the class robot_model::RobotModel? I know the questions can be separated, but there's a strong connection between all three. Thanks. |
2017-01-28 06:06:53 -0500 | asked a question | converting or mapping world (work space) cartesian space to joint space Many path planners sample and perform motion planning in joint space rather than Cartesian space. How do they get access to this joint configuration space? What mechanism is used to convert the robot work space and the collision objects present to joint configuration space? |
