This type of wheelchair is a different low-cost sensor modules, increasing safety in mobility for users of electrical wheelchairs. The implemented functionalities include navigation as well as obstacle avoidance support. As different sensor types are included to cover the same function, this system operates reliably for a broad range of environmental conditions. Within the hospital environment, these capabilities assist the nursing staff by enabling the
following functions:
convoy driving of several wheelchairs, autonomous transports on given routes, quick contact to the disabled person in case of emergencies.

    • Introduction.. • The need for an intelligent wheelchair simulator has its origin in the intelligent wheelchair project. • Mobile robots with capabilities to autonomously reach a target location despite obstacles are designed for a broad range of applications. • This includes in particular capabilities to avoid obstacles, to localise the actual position, to determine relative distances to specific objects and to accurately reach given target locations. • The main objective was to transfer related sensor technology to support disabled users of electrical wheelchairs. (Fig. 1. Wheelchair)
    • Working Mode... (Fig. 2. Overall Control Of Wheelchair)
    • Wheelchair Overview.. (Fig. 3. Overview Of Wheelchair)
    • (Fig. 4. SYSTEM ARCHITECTURE) SYSTEM ARCHITECTURE
    • Control Architecture.. Intelligent wheels project has a multilevel control architecture : The lower levels - basic control - are handled by the main application itself, separating the higher levels – tactical 4- level and the strategy level - from the Intelligence module. (Fig. 5. Control Architecture)
    • VARIOUS CIRCUIT USED .. FIG.5 R/F MODULE TRANSMITTER COTROLLER FIG.6 POWER CONTROL OF RF TRANSMITTER FIG. 7 R/F MODULE RECEIVER CIRCUIT
    • CONTINUED.. FIG.8 TIMER CONTROL CIRCUIT FIG.9 MAIN CONTROLLING CIRCUIT

    • Software Used.. • WinAVR • AVR Dude • Pony Prog • Eagle • AVR Studio • Keil uvision 4
    • Application.. • This electrical wheelchair is to assist disabled people in their mobility, by warning of obstacles in the way and by assisting in the navigation to return back home. Provides additional useful capabilities for the hospital environment, like convoy driving of several wheelchairs, or autonomous driving on given courses.
