+# `max_relative_target` limits the magnitude of the relative positional target vector for safety purposes.
+# Set this to a positive scalar to have the same value for all motors, or a list that is the same length as
+# the number of motors in your follower arms.
+# For Aloha, for every goal position request, motor rotations are capped at 5 degrees by default.
+# When you feel more confident with teleoperation or running the policy, you can extend
+# this safety limit and even removing it by setting it to `null`.
+# Also, everything is expected to work safely out-of-the-box, but we highly advise to
+# first try to teleoperate the grippers only (by commenting out the rest of the motors in this yaml),
+# then to gradually add more motors (by uncommenting), until you can teleoperate both arms fully
