What is claimed is:
1. Technical Field
The present disclosure relates to robots and, particularly, to a touch sensitive robot.
2. Description of Related Art
Touch sensitivity of most touch sensitive robots are realized by pressure sensors. However, because of a great number of pressure sensors required to make the entire body touch sensitive, the cost is exorbitant.
Therefore, it is desirable to provide a touch sensitive robot, which can overcome the above-mentioned problem.
Referring to
The body 10 includes a circular bottom board 12, a dome-shaped shell 14, an interaction section 16, and a pair of wheels 20. The circular bottom board 12 seals the dome-shaped shell 14. As such, the circular bottom board 12 and the dome-shaped shell 14 cooperatively define a closed space for accommodating various components of the touch sensitive robot 100. The interaction section 16 allows the touch sensitive robot 100 to mimic interaction. In this embodiment, the interaction section 16 is a control panel of the touch sensitive robot 100 and is mounted in the outer surface of the dome-shaped shell 14. However, in other alternative embodiments, the interaction section 16 can be in other form, corresponding to the type of touch sensitive robot. For example, the interaction section 16 can be a robotic head if the touch sensitive robot 100 is a representation of a human robot or an animal robot. The pair of wheels 20 is movably connected to the circular bottom board 12 to facilitate motion of the body 10. In particular, the pair of wheels 20 can rotate to propel the circular bottom board 12, the dome-shaped shell 14, and the interaction section 16 to move along/around. Also, the pair of wheels 20 can rotate independent of each other to drive the circular board 12, the dome-shaped shell 14, and the interaction section 16 to spin around.

The touch sensor 30 includes an isolating cover 32, a first conductive belt 34, and a second conductive belt 36.
As shown in
The first conductive belt 34 includes a first end 34a and a second end 34b. The first conductive belt 34 is almost as long as the isolating cover 32. In this embodiment, the first conductive belt 34 is made of a conductive material of a high elasticity, e.g., conductive rubber. As such, the first conductive belt 34 also deforms instantly when touched.
The second conductive belt 36 includes a third end 36a and a fourth end 36b. The second conductive belt 36 is also as long as the isolating cover 32. The electric resistivity of the second conductive belt 36 is different from that of the first conductive belt 34. In this embodiment, the second conductive belt 36 is made of copper. Accordingly, the electric resistivity of the second conductive belt 36 is lower than that of the first conductive belt 34.

Further referring to
In assembly, the power source 42 and the current sensor 44 are connected in series between the first conductive belt 34 and the second conductive belt 36. The power source 42 is configured for supplying electrical power to the first conductive belt 34 and the second conductive belt 36. The current sensor 44 is configured for measuring the flow of the electrical current through the first conductive belt 34 and the second conductive belt 36 when the first conductive belt 34 is touched and electrically contacts the second conductive belt 36. In this embodiment, the power source 42 and the current sensor 44 are connected between the first end 34a and the fourth end 36b. However, it is not limited to this embodiment, the power source 42 and the current sensor 44 also can be connected to any point of the first conductive belt 34 and the second conductive belt 36. The controller 46 is connected to the current sensor 44 and is configured for controlling the driver 48 based upon the measurement of the current sensor 44. The driver 48 is connected to the controller 46 and is configured for driving the pair of wheels 20 to rotate.
In operation, when a touch is performed on a point A of the isolating cover 32, both the isolating cover 32 and the first conductive belt 34 deform, e.g., bent towards the second conductive belt 36. The first conductive belt 34 and the second conductive belt 36 contact each other at the point A. The power source 42, the current sensor 44, a portion of the first conductive belt 34 from the first end 34a to the touch point (hereinafter “the effective first conductive belt”), and a portion of the second conductive belt 36 from the fourth end 36b to the touch point (hereinafter “the effective second conductive belt”) form a closed circuit. The flow of the electrical current of the closed circuit depends on the total resistance of the effective first conductive belt 34 and the effective second conductive belt 36. The flow of the electrical current of the closed circuit is measured by the current sensor 44. The total resistance of the effective first conductive belt 34 and the effective second conductive belt 36 depends on a location/position of the point A relative to the first conductive belt 34. In other words, the current sensor 44 can detect the location of the point A relative to the first conductive belt 34. Thereby, the controller 46 can control the driver 48 to drive the pair of the wheels 20 based upon the measurement of the current sensor 44. Accordingly, the pair of wheels 20 rotate independently of each other to spin the body 10 such that the interaction section 16 substantially changes position with the point A.
In the touch sensitive robot 100, only one touch sensor 30 is employed. In addition, the touch sensor 30 is made of inexpensive material and can be manufactured by simple processes. Therefore, the cost of the touch sensor 30 is low. As such, the cost of the touch sensitive robot 100 can be reduced.
It should be mentioned that the body 10 is not limited to this embodiment, but can be shaped and structured depending on the type of touch sensitive robot.
It should be noted that the touch sensor 30 is not limited to this embodiment. For example, the isolating cover 32 can be in other shapes, depending on practice requirements. The inner structure of the touch sensor 30 is not limited to this embodiment too. Any structure having a pair of spaced conductive belts can be used. Beneficially, the outer conductive belt has an excellent elasticity to deform in case of touch. The conductive belts better have different electric resistivities. In addition, the isolating cover 32, the first conductive belt 34, and the second conductive belt 36 can be elongated to wrap around the entire outer surface of the body 10.
The combination between the touch sensor 30 and the body 10 is not limited to this embodiment too. In other alternative embodiments, the touch sensor 30 can be attached to the body 10 using other techniques, e.g., adhesive.
While various exemplary and preferred embodiments have been described, it is to be understood that the invention is not limited thereto. To the contrary, various modifications and similar arrangements (as would be apparent to those skilled in the art) are intended to also be covered. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
