Benefits of technology

[0011] For an improved cooling effect, the shell may further comprise a torso air outlet provided on at least one of the lateral sides of the torso part of the shell, a torso air inlet hole provided in a downward facing part of the shell and a powered fan provided immediately inside of at least one of the torso air vent hole and the torso air inlet hole. Because the cooling air is allowed to flow upward centrally from a lower part of the torso part, the entire torso part ca...

Problems solved by technology

The inner space accommodating such components are typically so packed and enclosed that natural ventilation would not be adequate to control the inner temperature of the robot.
The air drawn from the lower part of the backpack portion tends to flow along the lateral sides of the inner componen...

Embodiment Construction

[0020] Referring to FIGS. 1 and 2;, the humanoid robot 1 (which is referred to simply as a robot hereinafter) embodying the present invention comprises a torso 2, a head 3, a pair of arms 4L and 4R, a pair of legs 5L and 5R and a backpack box 6. Each arm 4L (4R) includes an upper arm 7L (7R), a lower arm 8L (8R) and a hand 9L (9R). Likewise, each leg includes an upper leg 10L (10R), a lower leg 11L (11R) and a foot 12L (12R).

[0021] The head 3 is connected to the torso 2 via a neck joint 21. Each upper arm 7L (7R) is connected to the torso 2 via a shoulder joint 22 at an upper end thereof and connected to the corresponding lower arm 8L (8R) via an elbow joint 23 at a lower end thereof. The lower arm 8L (8R) is in turn connected to the corresponding hand 9L (9R) via a wrist joint 24. A middle part of each upper arm 7L (7R) is provided with an upper arm joint 25 so that the upper and lower parts of the upper arm can be rotated relative to each other around an axial line extending cent...

Abstract

A torso part (2) and a backpack part (6) of a humanoid robot are commonly formed by a shell that defines an inner space that accommodates a heat generating component such as a control computer (31) and a power module (32, 33). The shell comprises an air vent hole (45, 46) provided on one lateral side of the shell, an air inlet hole (47, 48) provided on the other lateral side of the shell and a powered fan (49) provided immediately inside the air vent hole. Because the cooling air can flow laterally across the inner space, the entire part of the heat generating component can contact the air flow, and a uniform cooling effect can be achieved with a minimum power consumption and a minimum noise generation.

Description

TECHNICAL FIELD [0001] The present invention relates to a cooling arrangement for a humanoid robot having heat generating components such as a control computer and a power module inside a shell that forms at least a torso part of the robot, and in particular to a cooling arrangement for a humanoid robot that can improve the cooling efficiency. BACKGROUND OF THE INVENTION [0002] Various forms of humanoid robots have been developed. Unlike stationary industrial robots that are employed in painting, welding, assembling and other manufacturing work, a humanoid robot is required to be more compact because of the need to move about in a limited space with a limited power resource. A typical humanoid robot includes a battery, a control computer and a power module for the purpose actuating various drive motors for moving the arms and legs thereof in a highly coordinated fashion, and such components are typically accommodated in the torso part of the robot as there is no other available spac...
