# The start at which to start the Cartesian path

# Mandatory name of group to compute the path for
string group_name

# Optional name of IK link for which waypoints are specified.
# If not specified, the tip of the group (which is assumed to be a chain)
# is assumed to be the link
string link_name

# A sequence of waypoints to be followed by the specified link,
# while moving the specified group, such that the group moves only
# in a straight line between waypoints

# If jump_threshold is set > 0, it acts as a scaling factor that is used to
# filter out large relative joint-space jumps in the generated Cartesian path.
# To this end, the average joint-space distance between consecutive waypoints
# is computed. If any joint-space distance is larger than this average distance
# by a factor of jump_threshold_factor, this step is considered a jump
# and the returned path is truncated before the step.
float64 jump_threshold

# If prismatic_jump_threshold or revolute_jump_threshold are set > 0, then for
# all active prismatic or revolute joints, the joint-space difference between
# consecutive waypoints is compared to the respective absolute threshold.
# If any threshold is exceeded, this step is considered a jump and the returned path
# is truncated before the step.

# Scaling factors for optionally reducing the maximum joint velocities and
# accelerations.  Allowed values are in (0,1]. The maximum joint velocity and
# acceleration specified in the robot model are multiplied by their respective
# factors. If a factor is outside its valid range (importantly, this
# includes being set to 0.0), this factor is set to the default value of 1.0
# internally (i.e., maximum joint velocity or maximum joint acceleration).
