• Haptic Control of Hydraulic Machinery Using Proportional Valves 

      Kontz, Matthew Edward (Georgia Institute of Technology, 2007-07-30)
      Supplying haptic or force feedback to operators using hydraulic machinery such as excavators has the potential to increase operator capabilities. Haptic, robotic, human-machine interfaces enable several enhancing features ...
    • Modeling and compensation for biodynamic feedthrough in backhoe operation 

      Humphreys, Heather Celeste (Georgia Institute of Technology, 2010-11-18)
      Biodynamic feedthrough occurs in many types of operator controlled machines where the operator is a passenger and the motion of the controlled machine excites motion of the human operator, creating unwanted feedback. It ...
    • Variable fidelity modeling as applied to trajectory optimization for a hydraulic backhoe 

      Moore, Roxanne Adele (Georgia Institute of Technology, 2009-04-08)
      Modeling, simulation, and optimization play vital roles throughout the engineering design process; however, in many design disciplines the cost of simulation is high, and designers are faced with a tradeoff between the ...
