Modular robot assembly kit, swarm of modularized robots and method of fulfilling tasks by a swarm of modularized robots

Abstract: The present invention pertains to a modularized robot having a robot platform configured to convey mobility and connectivity to external components to the modularized robot, a robot workhead configured to convey the ability to perform an operational task to the modularized robot, and a robot adapter attached to either the robot platform or the robot workhead and configured to mechanically link the robot platform to the robot workhead Moreover, a swarm of modularized robots and a robot system include such modularized robots

Analysis of successes and failures with a tele-operated mobile robot in various modes of operation

Abstract: The effect on failure rates of the way tele-operators interact with mobile robots is investigated. Human tele-operators attempted to move a robot through progressively more complicated environments with reducing gaps, as quickly as possible. Tele-operators used a joystick and either watched robots, while operating them, or used a computer screen to view scenes remotely. Cameras were either mounted on the robot to view the space ahead of the robot or mounted remotely so that they viewed both the environment and robot. Tele-operators completed tests both with and without sensors. Both an umbilical cable and a radio link were used.

A multilegged modular robot that meanders: Investigation of turning maneuvers using its inherent dynamic characteristics

Abstract: This paper deals with the motion of a multilegged modular robot. The robot consists of a set of homogenous modules, each of which has a body and two legs and is connected to the others through a three-degree-of-freedom rotary joint. The leg joints are manipulated to follow periodic desired trajectories, and the joints between the modules act like a passive spring with a damper. This robot has characteristic dynamic properties. Specifically, a straight walk naturally turns into a meandering walk by changing the compliance of the joints between the modules without incorporation of any oscillatory inputs. We first show that this transition is excited due to a Hopf bifurcation, based on a numerical simulation and Floquet analysis. Following that, we examine whether the maneuverability and agility of the robot increase by utilizing the dynamic characteristics inherent in the robot. In particular, we conduct an experiment in which the robot pursues a target moving across the floor. We propose a simple controlle...

An online stair-climbing control method for a transformable tracked robot

Abstract: Stair-climbing is a necessary capacity for mobile robots. This paper presents an online control method for the stair-climbing of a transformable tracked robot, Amoeba-II, and this robot is also an isomerism-modules robot with different mechanism modules. Based on the reasonable compartmentalization and kinematics analysis of the stair-climbing process, the coordination of the rotations of modules can reduce the slippage between tracks and terrain. To ensure that the robot can climb stairs with enough capability and stability, the stair-climbing criterion for the robot has been established based on the force analysis of each stage of the stair-climbing procedure. Meanwhile, the interference-avoiding criterion has been set up to avoid the interference between the non-tracked module of the robot and the stair. The experiment for the stair-climbing of the robot has been implemented to certify the validity of the online stair-climbing control method for a transformable tracked robot.

Design and implementation of reconfigurable modular humanoid robot architecture

Abstract: This paper describes the design and implementation of reconfigurable modular humanoid robot architecture. Our proposed architecture features three key concepts: 1) a reconfigurable mechanical structure; 2) a layered software model; and 3) an end-to-end real-time communication mechanism. Our proposed reconfigurable modular humanoid robot consists of several functional robots such as an arm robot, a mobile robot, and a head robot to realize an effective reconfigurable mechanism for expandability. Depending on many purposes of researchers and users, our reconfigurable modular humanoid robot can be used as some kinds of humanoid robots or as several autonomous functional robots. We design and develop a prototype modular humanoid robot consisting of five functional robots for evaluating our proposed architecture. The results of the experiences show the modular humanoid robot can achieve expandability by our reconfigurable mechanism.
