class pyrcf.components.controller_manager.command_accumulators.CommandAccumulatorBase

Bases: abc.ABC

Accumulation policies are functions that takes in commands from two controllers and decides how to generate a single command to be sent to the robot.

NOTE: this should ideally be done at joint level, but we are simplifying by doing accumulation at robot-level instead.

abstract accumulate(commands=List[RobotCmd]) → pyrcf.core.types.robot_io.RobotCmd

Accumulate the specified commands into a single command to be sent to the robot.

Parameters:

commands (List[RobotCmd]) – the robot commands from different controllers (in sequence).

Returns:

The final control command (action) to be sent to the robot.

Return type:

RobotCmd

Raises:

NotImplementedError – Raised if this method is not implemented by the child class.
