In a developing country like Nigeria, this technology would be very much effective to pave the way of communication of the physically disabled people. This system uses batteries to power the motor and a switching arrangement in order to switch on and off the motor and achieve desired movement. A chain based arrangement that connects motor to the wheel arrangement in order to drive the attachment. It will use a ball bearing integrated handle fabricated with efficient support in order to achieve directional movement. The attachment uses metal rods and pipe arrangement designed to be attached to a wheelchair front rods and thus clamp on the front wheelchair rods. The E wheelchair attachment is designed to automate wheelchairs and thus achieve efficient and easy transportation medium to patients as well as disabled people.

To prepare a full report that describes the full process of the design plus the outcome of the project. To design and construct an attachable wheelchair automator that will assist persons with limited mobility who cannot afford the expensive motorized wheel chair which cost upward of N363, 000.00.ģ.

To identify the best solutions in manual wheelchair conversion design into power chair/E- wheel chair or electric wheelchair.Ģ. The aims and objectives were achieved with the following results:ġ. The metals that were considered are mild steel because of its ease machinability. The electric motor for pow ering the device could be bought on the shelf. The design of the attachable manual wheelchair automator is from locally sourced materials are also standardized. The materials used in the design were locally available. The module to different powered wheelchairs Navigation module was considered in order to simplify the adaptation of Tests performed on the navigation system have shown satisfactory results Mobile base when an obstacle is detected. Simple collision avoidance is also implemented in order to stop the These aspects have been consideredĪs specifications for the navigation module of powered wheelchairs.ĭifferent autonomy levels of the navigation module and proper user Usability has to be managed without affecting the security andĮfficiency of the navigation module. Ones, prefer to directly control the robotic device and this aspect of Such a way as to be easily managed by the user. General, a robot device must be adapted to assistive applications in Increase the autonomy of elderly and people with motor disabilities. System provides the commercial wheelchair with a set of functions which This paper presents the design of a navigation systemĪnd its integration with a commercial powered wheelchair. Helping them to gain a level of independence at least in the activities With motor disabilities or to substitute their missing function thus This wheelchair has the potential to deliver increased freedom to a considerable consumer base.Īssistive technology is an emerging area where some roboticĭevices can be used to strengthen the residual abilities of individuals Extensive testing was performed to ensure design integrity. Whenever the motor shaft rotates then the sprocket of rear spindle starts rotating and thus the wheel starts moving.
In this wheelchair the chain is used to transmit power to drive wheel from the dc gear motor. The Sprocket gear is joined with chain which is connected with another smaller cassette that is mounted directly on motor shaft. The constructed wheelchair has a frame four rear wheels with two shafts units two front caster wheels for smooth turning and a chain driven gear train for power assist to rear wheel from motor shaft. Due to high sustainable stress, low cost and availability, Mild steel has been chosen over Aluminum, Cast iron, Stainless steel for frame material. The proposed wheelchair has been implemented with design, simulation and construction of the whole body. The purpose of this research work is to propose of an automatic wheelchair system which facilitates the users. Driving a manual wheelchair or crutches is a difficult task and past invented automatic wheelchair are not available in present market that can be bought and used for physically disable persons.
