1. A method performed by one or more processors of a robot, the method comprising:

  • determining a first measure of a property of the robot for a first time,wherein determining the first measure is based on first sensor data from a first group of sensors of the robot,wherein the first group of the sensors includes at least a given sensor of the sensors of the robot, andwherein the first sensor data for the given sensor directly indicates a known value, for a given variable, that is utilized in determining the first measure;

    determining a second measure of the property of the robot for the first time,wherein determining the second measure is based on second sensor data from a second group of the sensors of the robot,wherein the second group of the sensors excludes the given sensor and includes at least one additional sensor that is not included in the first group, andwherein no known value for the given variable is directly indicated by the second sensor data and wherein no known value for the given variable is utilized in determining the second measure;

    determining a final measure of the property of the robot for the first time based on the first measure and the second measure;

    generating one or more control commands based on the final measure of the property; and

    providing the one or more control commands to one or more actuators of the robot to control the one or more actuators based on the one or more control commands.
