Args:
  reload_urdf: Whether to reload the urdf file. If not, Reset() just place
    the minitaur back to its starting position.
  default_motor_angles: The default motor angles. If it is None, minitaur
    will hold a default pose (motor angle math.pi / 2) for 100 steps. In
    torque control mode, the phase of holding the default pose is skipped.
  reset_time: The duration (in seconds) to hold the default motor angles. If
    reset_time <= 0 or in torque control mode, the phase of holding the
    default pose is skipped.
