چکیده

Autonomous humanoid robots need high torque actuators to be able to walk and run. One problem in this context is the heat generated. In this paper we propose to use water evaporation to improve cooling of the motors. Simulations based on thermodynamic calculations as well as measurements on real actuators show that, under the assumption of the load of a soccer game, cooling can be considerably improved with relatively small amounts of water.

PSO-Based Path Planning Algorithm for Humanoid Robots Considering Safety

In this paper we introduce an improvement in the path planning algorithm for the humanoid soccer playing robot which uses Ferguson splines and PSO (Particle Swarm Optimization). The objective of the algorithm is to find a path through other playing robots to the ball, which should be as short as possible and also safe enough. Ferguson splines create preliminary paths using random generated para...

Exergy Analysis of Evaporative Cooling for Optimum Energy Consumption in Diverse Climate Conditions

In this paper, exergy of conditioned air, exergy efficiency, irreversibility, and entropy generation of common models of evaporative cooling have been investigated in five cities of Iran. Direct evaporative cooling (DEC), indirect evaporative cooling (IEC), and two-stage IEC/DEC as the most popular methods of cooling have been modeled. Atmospheric conditions are considered as the dead state of ...

Design of Backdrivable Mechanisms with Electro-Hydrostatic Actuators*

The importance of force sensitivity in robots that interact with unknown disturbance is acknowledged. For the manipulators, impedance controlled robots realized safe and robust object manipulation. For the legged mechanism, it is expected to enhance locomotion stability, since locomotion fundamentally is a manipulation of the center of mass. In order to maximize force sensitivity, both the forc...
