This research is the second result concerned with control of driving wheelchairs and elevating seats. The standing and lifting seat elevation of wheelchairs with general wheel are controlled by motor speeds of rear wheels. The third wheelchair with mecanum wheels can make the translational motions and is controlled by different method which is designed and applied by the appropriate electrical logic circuits. Two general moving type wheelchairs and translational moving type wheelchair using mecanum wheel can drive with joy stick. All three wheelchiars' seat can be elevated by extra switches attached in chair. Finally, this research paper proposes the practical control method and electrical circuits of power wheelchairs.
