Abstract
A robotic feeding system for physically challenged persons, having: a base rotatable about a first axis; a support on the base, the support being rotatable about a second axis, the second axis being perpendicular to the first axis; an extending member with a proximal end mounted to the support; and a food handling utensil mounted at a distal end of the extending member, wherein the distal end of the extending member is movable along a third axis, and wherein the third axis is perpendicular to the second axis.
Description
- The present invention relates to machines that serve food to physically incapacitated or otherwise physically disadvantaged persons.
- Mechanical systems currently exist for serving food to physically incapacitated or otherwise physically disadvantaged persons. Unfortunately, such systems tend to be large bulky systems that are complex to operate.
- Typically, mechanical feeding systems are really food dispensers, rather than food servers. For example, many mechanical feeding systems simply dispense food from the distal end of a tube. This substantially limits what particular types of foods the person is able to receive with the feeding system.
- What would instead be desired is a simple and easy to operate mechanical system that simulates the motions of a physically unimpaired person by picking up standard food from a plate and then serving the food to the user.
- In addition, it would be preferably that such feeding system is very easy to operate by a user, such that a physically disadvantaged person is able to feed himself/herself with little or no assistance from others.
- The present invention provides a simple and convenient machine that picks up and serves food to a person who is physically challenged.
- In one preferred embodiment, the present invention provides a robotic feeding system for physically challenged persons, comprising: a base rotatable about a first axis; a support on the base, the support being rotatable about a second axis, the second axis being perpendicular to the first axis; an extending member with a proximal end mounted to the support; and a food handling utensil mounted at a distal end of the extending member, wherein the distal end of the extending member is movable along a third axis, and wherein the third axis is perpendicular to the second axis.
- Preferably, the first axis is vertical and the second axis is horizontal. As such, the base pans (i.e. moves) side-to-side, the support moves vertically up and down, and the distal end of the extending member moves in-and-out (i.e.: away from the base and support).
- The food handling utensil may be a fork, spoon, spork, or other suitable utensil.
- In preferred embodiments, a tripod onto which the base is mounted is also included. Additionally, a positioning system may optionally be included to move the base about the first axis and the support about the second axis.
- The present inventor has built and successfully operated the present invention using a telescope positioning system as the positioning system, and a car radio antenna assembly as the extending member. This positioning system was operated using a hand-held control that controls movement of the telescope positioning system.
-
FIG. 1 is a perspective view of the present invention ready to pick up food from a plate. -
FIG. 2 is a perspective view of the present invention ready to serve food to a physically challenged person. - A
robotic feeding system 10 is provided to serve food, for example, to a physically challenged person.System 10 includes abase 12, asupport 14, an extendingmember 16 and afood handling utensil 18, as shown. Preferably,base 12 is rotatable about a first axis A1. However, the base does not need to be rotatable.Support 14 is mounted ontobase 12, withsupport 14 being rotatable about a second axis A2. Preferably, second axis A2 is perpendicular to the first axis A1, as shown. Extendingmember 16 has aproximal end 17 mounted to support 14; and afood handling utensil 18 mounted at adistal end 19 of extendingmember 16. Thedistal end 19 of extendingmember 16 is movable along a third axis A3, as shown. Preferably, third axis A3 is perpendicular to second axis A2. - Optionally, first axis A1 is vertical and second axis A2 is horizontal. It is to be understood, however, that the present invention is not so limited.
- Optionally, the
food handling utensil 18 may be a fork, as shown. Alternately, however,food handling utensil 18 may be a spoon, spork, or other suitable utensil. - In optional embodiments,
system 10 further includes atripod 20 onto whichbase 12 is mounted. It is to be understood, however, that the present invention is not so limited. For example, the present invention may also be positioned on top of a table, or counter, or as an attachment to a bed or wheelchair. - Optionally,
system 12 further includes apositioning system 22 that movesbase 12 about first axis A1 and also movessupport 14 about second axis A2. Alternatively, separate positioning systems may be provided forbase 12 and support 14. - In one embodiment of the invention built and operated by the present inventor,
positioning system 20 was built from a Meade™ telescope positioning system.Positioning system 20 may further include a hand-heldcontrol 22 that controls movement ofpositioning system 20. However, any suitable positioning system may be used. In addition, the control switch for the positioning system may be of any suitable type, known to those of skill in the art. Preferably, a control switch can be selected to accommodate the physical disabilities of the intended user. - In the
embodiment extending member 16 was built from a telescoping car radio antenna assembly. - An advantage of the present invention is that the
proximal end 17 of extendingmember 16 remains at substantially the same location in space during the time that food is picked up and served to the user. As such, the present invention operates with movement in only three axes (A1, A2 and A3). Such movement is very easy for a user to control. This is especially important in the case of physically challenged users, since such individuals are typically limited in the commands that they are able to give to their feeding systems. With the present invention, such persons need only control movement of the feeding utensil in three axes. Three axis movement is very intuitive since movement in each axis can be controlled sequentially. - Movement of the feeding system is illustrated in
FIGS. 1 and 2 as follows. InFIG. 1 , the system is ready to pick up food from a plate. The user extends extending member 16 (along its longitudinal axis A3) such thatfood handling utensil 18 picks up food on the plate on the table. Next, as show inFIG. 2 , the user rotates support 14 upwardly around second axis A2 and further extends member 16 (along its longitudinal axis A3) such thatfood handling utensil 18 is positioned to place the food in the mouth of a user sitting behind the table. - An advantage of the present invention is that a user typically need only move the system components of the device in two axes. Specifically, the user may only need to rotate
support 14 about axis A2 and extend/retract member 16 along axis A3. Such two axis movement would occur when the user sits directly in front of the feeding system. Preferably, theproximal end 17 of extendingmember 16 is positioned at approximately the same height as the physically challenged person's head. Such positioning would further facilitate easy feeding of the user. - In various embodiments, the present invention may be positioned on a free-standing
tripod 20 that is positioned on the ground, as illustrated. Alternatively, however,system 10 may instead be positioned on a podium, pedestal or tabletop. - Although the present invention has been described in connection with preferred embodiments thereof, it will be appreciated by those skilled in the art that additions, deletions, modifications, and substitutions not specifically described may be made without department from the spirit and scope of the invention as defined in the appended claims.
