Robot to human feedback
Example implementations may relate to a robotic system configured to provide feedback. In particular, the robotic system may determine a model of an environment in which the robotic system is operating. Based on this model, the robotic system may then determine one or more of a state or intended operation of the robotic system. Then, based one or more of the state or the intended operation, the robotic system may select one of one or more of the following to represent one or more of the state or the intended operation: visual feedback, auditory feedback, and one or more movements. Based on the selection, the robotic system may then engage in one or more of the visual feedback, the auditory feedback, and the one or more movements.
1. A method comprising:
determining, by a robotic system, a motion path of a user in an environment of the robotic system;

based on the determined performance metric, selecting, by the robotic system, a first feedback mode, wherein the first feedback mode comprises at least one indication to the user;
engaging, by the robotic system, in the first feedback mode;
determining a change in the performance metric based on a change in the position of the user;
based on the determined change in the performance metric, selecting, by the robotic system, a second feedback mode, wherein the second feedback mode comprises at least one additional indication to the user different than the at least one indication of the first feedback mode; and
engaging, by the robotic system, in the second feedback mode.

10. The method of claim 1 , wherein engaging in the first feedback mode comprises repositioning of the robotic system from a first location in the environment to a second location in the environment.
11. The method of claim 1 , wherein engaging in the first feedback mode comprises the robotic system repositioning an object in the environment from a first location in the environment to a second location in the environment.
12. The method of claim 11 , wherein the first location is in a path of the user, and wherein the second location is away from the path of the user.
13. The method of claim 1 , wherein engaging in the first feedback mode comprises projecting light from one or more light sources of the robotic system towards an area of interest.
14. A robotic system comprising:
one or more processors;
a non-transitory computer readable medium; and
program instructions stored on the non-transitory computer readable medium and executable by the one or more processors to:
determine an intended path of a user in an environment of the robotic system;
based on the intended path of the user in the environment, determine a performance metric corresponding to a position of the user along the intended path;
based on the determined performance metric, select a first feedback mode, wherein the first feedback mode comprises at least one indication to the user;
engage in the first feedback mode;
determine a change in the performance metric based on a change in the position of the user;
based on the determined change in the performance metric, select a second feedback mode, wherein the second feedback mode comprises at least one additional indication to the user different than the at least one indication of the first feedback mode; and
engage in the second feedback mode.
15. The robotic system of claim 14 , wherein the first and second feedback modes comprise different types of visual indicators.
