SELF-ASSISTING ROBOT AND METHOD FOR TRANSFERRING A PARAPLEGIC USER TO AND FROM A WHEEL CHAIR
A robot that assists a user to transfer from a wheel chair to another location and vice versa.
A self-assisting robot for transferring a user from
a wheel chair to another location and vice versa in
accordance with an embodiment of the present invention
There are three different types of devices that assist a user from a wheel chair. The first type is the simple mechanical type without any automatic mechanism to assist the transferring of the user to and from the wheel chair that needs the assistance of a nurse to transfer the user from a wheel chair. The second type is the semi-automatic device that still needs some human assistance. The third type is the fully automatic device that does not need the assistance of a nurse.
It is easy to understand that the first type of user transfer device is inconvenient for both the user and a nurse because the user needs complete assistance from the nurse. Furthermore, to reduce the human assistance in the first type of user transfer device, either a specially designed toilet (self-rotating toilet seat) or a user lift hanging from the ceiling needs to be deployed. These types of devices increase costs and still require full assistance from a nurse.
In the semi-automatic user transfer devices, a special cart is provided just to move a user to and from a toilet seat. At the toilet seat or the wheel chair, a nurse needs to present in order to move the user onto the toilet seat or back to the wheel chair. These devices cost money and still require human labor.
Finally, in the conventional automatic user transfer devices such as the self-transfer aid robotics by Yoshihiko Takahashi. Even though the robotic eliminates assistance from a nurse, it is still not preferred by users for the reasons discussed below.
Therefore what is needed is a user lift that can overcome the above described problems.
Summary of the invention
An objective of the present invention is to provide a self-assisting robot for assisting a paraplegic user is disclosed which comprises a platform having a plurality of wheels, a robotic arm, an inclination sensor, operable to measure the inclination angle formed between said platform and a road in front thereof, a saddle configured to be adjusted up and down to fit the height of a user, a controller panel connected to the saddle, a processor operable to control the operations of the self-assisting robot, and a kneeling seat connected to and move with the robotic arm.
These and other advantages of the present invention will no doubt become obvious to those of ordinary skill in the art after having read the following detailed description of the preferred embodiments.
