Abstract
In order to make disabled people travelling by electric wheelchairs more saferly and reliably
an automatic leveling device is designed to adjust the stability of seats. Based on combination of micro-electromechanical systems( MEMS) inclination sensor and automatic leveling technology
a electromechanical four-point diamond leveling system is established. By using the position inverse solution in kinematic analysis
theoretical parameters are calculated and determined according to model. At the same time
the field experiment of the designed automatic leveling device is carried out
and the automatic stable and fast leveling of wheelchair seats in inclination range from 0 °to 30 °is realized.
