monolith_continous_perform_action(action, channel_type, algorithm_mode)

Perform an action on the robot

Parameters

• action_type – FourDiscreteMotionActions type value with the action to execute.

• channel_type – Channels type value, determines observation’s channel.

• algorithm_mode – Whether algorithm is being run in train or test modde.

Returns

A numpy array as the observation. An integer value represeting reward from the environment. A boolean value that indicates whether episode is done or not.

Requests server to reset the environment.

Parameters

channel_type – Channels type value, determines observation’s channel.

Returns

A numpy array as the observation.
