Wheelchair Simulator

Wheelchair Simulator

Task

Software redevelopment for the control of a wheelchair simulator within the public area of the Science Center Medical Technology in Berlin.

Requirements

  • Control improvement of the pneumatic platform simulating the roll and pitch angle and surface properties
  • Control and evaluation improvement of the force feedback system simulating the rolling resistance dependent on the pitch angle for each wheel
  • Control and evaluation improvement of the 3D course visualization
  • Runtime refinement for a more realistic simulation
  • High reliability
  • Simplest usage
  • Function supervision using an intelligent realtime watchdog
  • Remote serviceability of the software
Wheelchair Simulator Controlled by LabVIEW and LabVIEW Real-Time/RT

Solution

Software development and programming in LabVIEW for the PC and in LabVIEW Real-Time/RT for the FieldPoint system (both National Instruments). Ethernet communication between the modules using TCP/IP. Obtained control cycle time: 15ms.
