The scope of the project are
also has been discussed in this week and I have decided to make the scope of
the project to make the specification of the project is clear and follow the
objective. It is shown as below:
The scope of this project is to develop the walker which can be
used by elders or handicapped person that can be controlled using remote
sensing. This walker is suitable for general purpose
which it provides a stable and mobile walking frame and is adapted to move
forward or reverse and move left or right according to a users needs. This
walker can be operate by using lead acid battery 12VDC (Power window motor),
10VDC (Receiver circuit) and 9VDC (Transmitter circuit). The user
controls the movement of the walker by depressing a switch at RF remote control
or switch at the walker frame and the speed of this walker also can be
controlled. This walker has special features and easy to be carried to
anywhere. For example, this walker can be used if the users want to go to
indoor or outdoor environment such as cafeteria, playground or other place. If
users want to put the walker somewhere, it only need to use RF remote to move
the walker to certain place or parking area. This walker also can be returned
to the user when signalled by RF remote control.
I have also studied from the previous project that have been innovate from the invntor before to make the differentiation between them to see their objective:
- Cornell biomedical engineering students working with Weill Cornell Medical College-affiliated psychiatrist Dr. Eli Einbinder: They have designed an electronic braking system for walkers, with buttons replacing bicycle-style squeeze brakes. Their walkers also have automatic braking that can prevent slips, slides and falls when a user grabs the handgrips.
- Doctorate Dissertation submitted by Win-Bin Shieh, to the University of Maryland, 1996. "Design and Optimization of Planar Leg Mechanisms Featuring Symmetrical Foot-Point Paths." Of note, Win-Bin Shieh identifies six "admissible" one degree-of-freedom (DOF) planar four-bar, six-bar and eight-bar mechanisms with desirable features.
