Geobot 2
For evaluating outdoor navigation, movements, and sample collection.


Above: The head rotates, lights with a dozen different combinations of lights,
PID drive is working well, robot sound effects are in place, and now we are adding a tripple axis magnetometer for
navigation.

Here is the latest
      on the Geobot. The huge project of designing and building a 4
      channel motor controller with PID drive for all four motors is
      done, and awaits full testing on the actual robot. How will it
      react with all four trying to maintain speed at the same time?
      We shall see.

      

        

          
 
          
 Just
            before the tower was permanently mated to the motor drive base.
            You can see the terminal blocks for the motors through the top
            lexan platform, and the quad motor controller on the front edge.
            The large black box is the lead acid battery - and rear ballast
            for the future arm.
 
        
      

        

          
 
          
 The
            tower installed and we are starting to wire it in. All the primary
            power wiring is done - which provides 12v to the motor drivers,
            and to the 5v regulator power board, with six independent 5v
            regulators to power future additions!
 
        
      

        

          
 
          
 The
            front side of the tower will eventually house the fold up arm.
            One version of the gripper is allready done and motorized.
 
        
      

        

          
 
          
 The
            inside of the tower so far has my custom designed microcontroller
            robot PCB inside (PIC 16F887 processor) and just below it is
            the 6 output power regulator board (hand built). Look closely
            and you can see the big U shaped heat sink that connects the
            regulators and wraps around the battery.
