Enhancements to mechanical robot

Abstract

A mechanical robot senses smoke or CO or other indication of air quality and alarms when air quality falls below a threshold.

What is claimed is: 
     
         1 . A mechanical robot, comprising:
 a body;   at least one processor mounted on the body;   at least one electro-mechanical mechanism controlled by the processor to cause the body to ambulate;   an airborne sensor on the body and outputting signals representative of air content;   a spectral analysis device receiving signals from the airborne sensor and outputting an analysis signal representative thereof; and   an alarm on the body for selectively alarming based on the analysis signal.   
     
     
         2 . The robot of  claim 1 , wherein the sensor is a CO sensor. 
     
     
         3 . The robot of  claim 1 , wherein the sensor is a CO2 sensor. 
     
     
         4 . The robot of  claim 1 , wherein the sensor is a smoke sensor. 
     
     
         5 . The robot of  claim 1 , wherein the spectral analysis device is implemented by the processor. 
     
     
         6 . The robot of  claim 1 , wherein the spectral analysis device is implemented in the sensor. 
     
     
         7 . A mechanical robot, comprising:
 a body;   at least one processor mounted on the body;   at least one electro-mechanical mechanism controlled by the processor to cause the body to ambulate;   means on the robot for sensing airborne material; and   means on the robot for selectively alarming in response to the means for sensing.   
     
     
         8 . The robot of  claim 7 , wherein the means for sensing is a CO sensor. 
     
     
         9 . The robot of  claim 7 , wherein the means for sensing is a CO2 sensor. 
     
     
         10 . The robot of  claim 7 , wherein the means for sensing is a smoke sensor. 
     
     
         11 . A method for alerting a person to hazardous air quality, comprising:
 providing a mechanical robot;   causing the robot to ambulate;   causing the robot to sense at least one indicia of air quality; and   causing the robot to alarm if the indicia exceeds a threshold.   
     
     
         12 . The method of  claim 11 , wherein the indicia is smoke. 
     
     
         13 . The method of  claim 11 , wherein the indicia is CO. 
     
     
         14 . The method of  claim 11 , wherein the indicia is CO2.
