A bionic sweat gland and a bionic skin include a shell and a porous medium. A heat dissipation pipe is arranged inside the shell, that is filled with porous media. The pores formed by the porous medium in the heat dissipation pipe gradually decrease along the evaporation flow direction and the gap of the porous medium is filled with evaporation liquid. The shell is a permeable structure, which is used to absorb evaporation liquid from the environment. The top of the shell is provided with a number of through holes connected with the heat dissipation pipe for discharging evaporation liquid to the outside. The bionic sweat gland and the bionic skin can adapt to the effect of tensile and shear forces generated on the surface of flexible materials such as electronic skin during use.

There is provided a continuum robot comprising a first end, a second end and an elongate body, a sensor arranged at the first end and a cooling jacket adjacent the sensor. The cooling jacket comprises a cavity containing a cooling medium for absorbing heat from the sensor.

A leg structure of a quadruped robot includes a body and four separate leg modules. Each leg module includes a thigh motor assembly, a calf motor assembly, a hip joint motor assembly and an associated linkage and fixing base of the hip joint motor assembly. The hip joint motor drives the thigh and calf assembly through a parallelogram mechanism, the thigh motor assembly directly drives the thigh rod assembly, and the calf motor assembly drives the calf assembly through an anti-parallelogram mechanism. The joint motor assemblies are independent of each other and all the motor assemblies are modularized; the thigh and calf motor assemblies have a good ability to prevent external impact, and the joints on the robot body, formed by using the motor assemblies, have a large working space, thus ensuring the movement flexibility of the robot.

A communications module is provided for simplifying routing of communications pathways in a robot. The communications module is attached between the robot tool flange and the end effector. Additional interchangeable modules may also be provided between the tool flange and the end effector. The communications module includes multiple input ports and at least one output port. A data switch within the module combines sensor data from multiple input ports into a single output stream that is transmitted from one or more of the output ports.

A processing module is provided for improving performance of a robot. The processing module is attached between the robot tool flange and the end effector. Additional interchangeable modules may also be provided between the tool flange and the end effector. The processing module includes a processor that processes sensor data received from one or more sensors. The processor generates lower bit rate processed sensor data from the incoming sensor data. The processed sensor data is transmitted from the processing module to another processor of a robot controller.

A sensor module is provided for adding functionality to a robot. The sensor module is attached between the robot tool flange and the end effector. Additional interchangeable modules may also be provided between the tool flange and the end effector. The sensor module includes a sensor for monitoring a condition near the end effector. An output port of the module transmits sensor data to a processor outside of the sensor module for further processing.

A robot includes a robot main body section including a base and a robot arm coupled to the base and including a sealed internal space, a driving section provided on the inside of the robot arm and configured to drive the robot arm, a control board provided on the inside of the base, a power supply board provided on the inside of the base and configured to supply electric power to the control board, a driving board provided on the inside of the robot arm and configured to drive the driving section based on a signal from the control board, a fan configured to stir gas on the inside of the robot main body section, and a heat sink provided on the inside of the base.

A robot device includes an arm mechanism that includes links and joints. A hand is mounted to a tip of the arm. A motor driver drives motors of the joints. A processor outputs, to the motor driver, a command value for moving a reference point of the hand to a target position. A storage device stores a first thermal displacement amount temporal variation representing a variation with respect to a continuous operation time period in a thermal displacement amount by which the hand reference point is displaced from a cool position to a heat balance position due to heat generation accompanying operation of the arm mechanism, and a second thermal displacement amount temporal variation representing a variation with respect to a continuous stopped time period in a thermal displacement amount by which the hand reference point returns from the heat balance position to the cool position accompanying stopping of operation of the arm mechanism. The processor refers to the first and second thermal displacement amount temporal variations to estimate a thermal displacement amount of the hand reference point based on the continuous operation time period and continuous stopped time period of the arm mechanism, and corrects the target position based on the estimated thermal displacement amount.

A robot including: a driving mechanism that drives a movable member with respect to a base; and a fan that cools the driving mechanism, wherein the driving mechanism is provided with a motor, and a reducer that is disposed between the base and the movable member and that moves the movable member with respect to the base by reducing the speed of the rotation of the motor, the motor and the reducer are disposed on either side of a securing plate that is secured to the base, the cooling fan is disposed on an opposite side from the securing plate with the motor interposed between the fan and the securing plate, a space in which a surface of the reducer is exposed is formed outside the reducer, and the securing plate is provided with a vent that is connected to the space by passing through the securing plate.

A cooling device for cooling electrical components of a robot control device with cooling air flow generated by a fan having a first receiving space for first electrical components, a second receiving space for second electrical components, and a cooling body wall fluidically separating the first receiving space from the second receiving space. The cooling body wall has a first separating wall surface facing the first receiving space and an opposite second separating wall surface facing an intermediate space of the cooling body wall. The second separating wall surface includes cooling wall projections that form at least one flow channel. The cooling body wall has a cooling air passage opening that is designed to convey a cooling air flow conveyed by at least one fan of the cooling device from the first receiving space, through the cooling body wall, into the intermediate space.
