Human Robot Interaction
Carrying and placing the printed panels to form walls/ceilings:
Co-manipulation tasks (such as carrying and placing Voronoi panels) require human(s), robot(s) and the environment to come to contact with each other and form a tightly coupled dynamical system . Within such Physical Human-Robot Collaborative (pHRC) tasks, trajectory corrections are often frequent and necessary due to the robot’s lack of a higher-level understanding of human actions. Humans often demonstrate diverse behaviours due to their personal preferences, for instance related to their individual execution style or personal margin for safety. If the robot can gain an understanding of such user preferences, then it would be able to considerably improve its collaborative behaviour for different scenarios, reducing the need for additional corrections or adaptations.
In the proposed framework, the robot learns a context aware human trajectory preference model via coactive learning . Based on a few initial demonstrations the robot updates the weights in its trajectory preference model that correspond to the features (i.e. preferences) the user intends to change. Prior to each collaborative episode, the robot combines its own objective function and the preference model to plan its behaviour in a way that adheres to both task requirements and user preferences (via trajectory optimization). Finally, a hybrid force/impedance controller  is used to track the resulting trajectory and force behaviour.
Preliminary results from simulations (Fig. 1) show that the robot is capable of generalizing the learned preferences to new scenarios, eliminating the need for repeated demonstrations. Furthermore, the framework is expected to achieve improved collaboration and to decrease effort from the perspective of the human partner. In the next steps, the method will be going under further development to include more preferences, and consequently will be tested on a real robot platform in a physical human-robot collaborative manipulation task.
Figure 1: Top: User demonstrates their preferences of staying close to the ground surface and passing on the right side of obstacles in the learning phase. Bottom: The robot generalizes and executes trajectories that adhere to the user’s preferences in different scenarios.
