articulations-robot-demo VS URDF-Importer

I'm trying to modify this demo, which uses the UR3 robotic arm with ML-Agents (Release 1.2.0 in Unity 2020.3.46f1). I want to add imitation learning, but there seems to be an issue with the manual controls. All joints work fine except Wrist01 (which should use the O/P keys). Wrist01 moves on its own and ignores O/P key input (in the clip I rotate the base at 00:06, but I never touch the wrist controls). Something's likely wrong with one of these files: "RobotController" (called by the parent UnityRobotics GameObject), "ArticulationJointController" (called by the child Wrist01 GameObject), or "RobotManualInput" (called by the ManualInput GameObject), but I can't for the life of me identify where the error is. Anyone know what's going wrong?

For reference i am using https://github.com/Unity-Technologies/articulations-robot-demo Robotiq Hand-E Gripper. It can only go up and down but I'm trying to make it go left and right as well.

From my experience, ROS# is not the recommended way to connect Unity and ROS anymore. You probably want to use the ROS-TCP-Connector which is officially supported by Unity and its corresponding ROS package. That page has quite a few tutorials to help you get the connection setup. I currently maintain a plugin that implements a set of commonly used sensors here which might be of some use to you. Another useful resource maintained by Unity is their URDF importer, but it is still a bit buggy. Let me know if you need any other resources or help, I'm trying to make Unity a bit more livable for ROS developers.
