ROBOT CAPABLE OF TRANSFORMING BETWEEN A VEHICLE POSTURE AND A ROBOT POSTURE

Description

TECHNICAL FIELD

This invention relates to a robot capable of transforming between a vehicle posture and a robot posture.

BACKGROUND TECHNOLOGY

Conventionally, drivable robots made of resin that can transform between a vehicle posture and a drivable posture are known. In conventional drivable robots made of resin, the robot body and shoulders are large in size and volume, and heavy. However, simply reducing the size of each part does not allow smooth and reliable transformation between the robot posture and the vehicle posture, and therefore the volume and weight of the robot cannot be reduced, and it is not possible to reduce the size or weight.

SUMMARY OF THE INVENTION

Problem to be Solved by the Invention

This invention relates to a robot that can be transformed and driven between a robot posture and a vehicle posture by reducing the size and weight of the robot and largely reducing the robot posture and the vehicle posture, thereby significantly reducing the space required to accommodate them and significantly reducing material costs.

More specifically, by forming a rotation shaft between the robot body and the shoulder part from a high-strength metal, the size and capacity of the rotation shaft can be reduced, and the size, capacity and weight of the robot body and shoulder part can be significantly reduced. As a result, the size, capacity and weight of the robot can be significantly reduced, making it possible to significantly reduce the weight and cost of the robot.

Means for Solving the Problem

Claim 1

The present invention is a drivable robot that can be transformed between a vehicle posture and a robot posture, and comprises a robot body 1, a head 2 attached to the top of the robot body 1, shoulders 3 attached to both sides of the robot body 1, arms 4 attached to the bottom of the shoulders 3, thighs 5 attached to the bottom of the robot body 1, legs 6 attached to the bottom of the thighs 5, and a hip joint Y attached between the robot body 1 and the thighs 5 (posture a), wherein the front part 10 of the vehicle body is formed by bringing a pair of the legs 5 and legs 6 close to each other (posture b), the rear part 11 of vehicle is formed by bringing the shoulders 3 together by rotating the vehicle front part 10 back and forth, the vehicle door part 12 is formed with both arms 4 open horizontally (posture c), the vehicle front part 10 is formed on the back side by rotating the vehicle front part 10 back and forth (posture d), and the vehicle is formed by closing the door parts 12 (posture e) and the drivable robot and the vehicle body can be transformed in both directions, and a rotation axis between both shoulders and the main body and a rotation axis between the shoulders and the arms are made of a highly rigid metal, and the robot main body, the head, both arms, both thighs, both legs and the axis Y of the hip joint are made of ABS resin, so that the drivable robot that can transform into the vehicle posture.

Claim 2

The drivable robot described in (1), wherein the rotation axis X1 between the robot main body and the shoulders and the rotation axis X2 between the shoulders and the arms are made of highly rigid aluminum metal, aluminum alloy or steel.

Effects of the Invention

The rotation between the robot body 1 and both shoulders 3, and the rotation between the shoulders 3 and the arms 4 are large, but because the rotation axis X1 between the robot body 1 and both shoulders 3, and the rotation axis X2 between the shoulders and arms are made of highly rigid metal, these rotations are sufficiently stable and occur smoothly even when their size is reduced, whereas because the movement of the hip joint itself is large and simple, even if the hip joint axis Y is made of ABS resin, smooth rotation between the robot body and the thigh is possible. As a result, the size of each part of the robot can be significantly reduced, and the weight can also be significantly reduced.

As a consequence, the main body 1, head 2, shoulders 3, and arms 4 can be significantly reduced in size and weight, so that the size and weight of the other parts, such as the thigh 5, legs 6, and hip joint Y, can also be reduced accordingly.

Therefore, the robot posture and the vehicle posture can be significantly reduced in size, and a space required to accommodate them can be significantly reduced.

EMBODIMENT FOR CARRYING OUT THE INVENTION

The robot that can be transformed and driven between the vehicle posture and the vehicle posture according to the invention described above will be described based on an embodiment. This embodiment is merely an example of the invention, and the invention should not be understood as being limited to this embodiment alone. It will be clear to those skilled in the art that various modifications and variations are possible within the scope of the invention claims.

Example 1

FIGS. 1 and 2 show plan views of the robot posture of the robot according to the invention. The robot of the invention comprises a robot body 1, a head 2 provided on the upper part of the robot body 1, shoulders 3 provided on both sides of the robot body 1, arms 4 provided below the shoulders 3, thighs 5 provided below the robot body 1, legs 6 provided below the thighs 5, and a hip joint Y provided between the robot body 1 and the thighs 5. In the robot according to the invention, the rotation axes X1 and X2 are made of a highly rigid metal, such as aluminum, a lightweight aluminum alloy, or a stainless steel alloy, and the other members are made of synthetic resin such as ABS resin. In the robot according to the present invention, the rotation axis X is made of a highly rigid metal, so even if the size of the robot body 1, shoulder 3, and arm 4 is reduced, the robot body 1 and shoulder 3 can rotate smoothly, and the shoulder and arm 4 can rotate smoothly, resulting in excellent strength and durability.

Meanwhile, the hip joint Y between the thigh 5 and the robot body 1 can be sufficiently large in diameter, so that rotation between the robot body 1 and thigh 5 of the robot according to the present invention can be made smoothly.

Next, FIG. 3 and FIG. 4 show the state (front and back sides) of the robot according to the present invention, which changes from the robot posture to the vehicle posture. FIG. 3(a) and FIG. 4(a) show the standing and lying states of the robot posture of the robot, respectively, and FIG. 3(b) and FIG. 4(b) show the pair of thighs 5 and legs 6 of the robot in the robot posture of the robot closed to form the front body 10. FIG. 3(c) and FIG. 4(c) show the state in which the shoulders 3, 3 are brought together to form the rear body 11, and the arms 4, 4 form the door parts 12, 12 in the car mode.

FIG. 3(d) and FIG. 4(d) show the state in which the front part of the car is turned upside down, and FIG. 3(e) and FIG. 4(e) show the state in which the door parts in the car mode are closed.

FIG. 5(a) is an example of a vehicle posture of the robot according to the present invention, in which aluminum metal shafts (1 mm diameter) are used for the rotating parts of the body, shoulders, and arms, and all other parts are formed from ABS resin, while it is an example of a vehicle posture of a conventional robot in which the rotating shafts (3.5 mm diameter) of the body, shoulders, and arms are all made of ABS resin.

The robot according to the present invention uses aluminum metal shafts (1 mm diameter) for the rotating parts of the body, shoulders, and arms, and all other parts are formed from ABS resin. On the other hand, compared to a conventional robot (approximately 8 cm×approximately 3 cm×approximately 2.5 cm) in which the rotation axes of the robot body 1, shoulders 3, and arms 4 are also made of ABS resin (3.5 mm diameter), it can be seen that the size can be reduced to approximately 2.2 cm×approximately 1.2 cm×approximately 0.7 cm, and the weight can be reduced to approximately one tenth.

INDUSTRIAL APPLICABILITY

In the robot according to the present invention, the rotation axis between the robot body and shoulders, which has a large rotational movement, and the rotation axis between the shoulders and arms are made of highly rigid metals such as aluminum, lightweight aluminum alloys, or stainless steel alloys, and the other members are made of synthetic resins such as ABS resin. This allows the rotation between the robot body 1 and shoulders 3 and the rotation between the shoulders and arms 4 to be smooth, and maintains high durability and strength, even if the size of the robot body 1, head 2, shoulders 3, and arms 4 is reduced.

The size of other parts can be reduced accordingly, and as a result the size, capacity and weight of the robot can be greatly reduced, making it possible to significantly reduce weight and costs.
