as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...

In order to better study the trajectory of robot motion, a motion trajectory planning and simulation based on 6-DOF manipulator arm robot is designed. Three and five polynomial methods are adopted to plan motion trajectories. The advantages and disadvantages of the three and five polynomial trajectory planning are summarized. The trajectory planning in the right angle space can make the robot a...

in this project guidance and control of underwater robot, including three engines and propeller attached to it, by fuzzy control has been investigated. fuzzy control is done based on human experience and requiered laws. the robot can also be controlled and guided by the user. this robot may be used in sea or swimming pool environment for finding goal point and locate in desired direction. in ad...

The discovery of three pentaquark peaks -- the $P_c(4312)$, $P_c(4440)$ and $P_c(4457)$ by LHCb collaboration has a series interesting consequences for hadron spectroscopy. If these hidden-charm objects are indeed hadronic molecules, as suspected, they will be constrained heavy-flavor SU(3)-flavor symmetries. combination two symmetries imply existence five-flavor pentaquarks with quark content ...

The study presented in this paper explored the relationships between participant personality, perceived robot personality and preferences for particular robot appearances. The participants (N=77) watched 3 videos of a HRI situation in which the appearance of the robot was altered to appear more or less anthropomorphic. Participant personality was assessed using the Big Five Domain Scale, while ...

At the 1992 AAAI robot contest one of the top finishers was Scarecrow – a robot that had no computer in the traditional sense, was built out of less than $200 of parts, and was explained and operated by a five year old. The designers sought to demonstrate the capabilities and competence that can be accomplished by using a strictly reactive architecture for well defined tasks such as that contes...

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

This study characterized the design and implementation of a low-cost autonomous robot capable of performing obstacle avoidance using neural networks trained with simulated sensor data. The only sensor used for detecting the environment was an infrared distance sensor attached to a hobby servo, allowing for 180° of sensor visibility. In order to train the neural networks, simulated sensor data w...
