I have the same kind of problem.

I know which robot configuration (F/N U/D T/B) I have to apply to my FANUC robot targets. I am unable to set it up with the robodk api.

Resulting in bad robot moving.

I replied to the thread on GitHub with an example to pick a joint solution based on a desired configuration. I'm also pasting the example here:

Code:

# Retrieve all solutions for a given pose:
all_solutions = robot.SolveIK_All(pose, toolpose, framepose)
joints = []

# Iterate through each solution
for j in all_solutions:
   # Retrieve flags as a list for each solution
   conf_RLF = robot.JointsConfig(j).list()

   # Breakdown of flags:
   rear  = conf_RLF[0] # 1 if Rear , 0 if Front
   lower = conf_RLF[1] # 1 if Lower, 0 if Upper (elbow)
   flip  = conf_RLF[2] # 1 if Flip , 0 if Non flip (Flip is usually when Joint 5 is negative)

   # Look for a solution with Front and Elbow up configuration
   #if conf_RLF[0:2] == [0,0]:
   if rear == 0 and lower == 0:
       print("Solution found!")
       joints = j
       break

We'll be updating the documentation in the upcoming days to also show this example.

I there a way to modify a joint target from the API by moving the cartesian coordinates without knowing what the final robot joints will be?

Yes, you can recalculate the target joints by first making the target a Cartesian target, let RoboDK recalculate the joints and then change it to a Joint Target.

This example shows the concept:

Code:

target.setAsCartesianTarget()
target.setPose(new_pose)
target.setParam("Recalculate")
target.setAsJointTarget()
new_joints = target.Joints()

This is wonderful! Thank you so much Albert!
