If a robot system can take various shapes, then it can play various roles, such as humanoid, dog robot, and robot arm. A modular robot is a robot system in which robots are configured using multiple modules, and it is possible to configure robots of other shapes by varying the combinations of the modules. In conventional modular robots, the shape is restricted by gravity, and configurable shapes are limited. In this study, we propose a gravity compensation modular robot to solve this problem. This paper describes the design and prototyping of the gravity compensation modular robot, and provides examples of robot shapes configured using the gravity compensation modules and motion experiments of the robots. In the experiments, there were motions that the robots could perform and could not perform. We considered the lack in the gravity compensation level and module rigidity as the main factor of the failures. This paper also discusses the solutions to these problems.

This paper describes the development of a modular humanoid robot based on our proposed functionally distributed modular robot architecture. Our proposed architecture features three key concepts, 1) a modular humanoid robot, 2) a functionally distributed module, and 3) a transparent layered software model. Our humanoid robot is designed as a modular robot system consisting of several functionally distributed modules with exclusive mechanical parts, electronic parts, and software for elemental functions such as leg, arm, and vision. Depending on many purposes of researchers and users, our humanoid robot can be used as some kinds of humanoid robots or several autonomous robots, e.g., a wheel robot, an arm robot, or a head robot. We developed the prototype modular humanoid robot consisting of five functionally distributed modules such as two arm modules, a wheel module, a head module, and a main module for evaluating our proposed architecture.

This paper describes subjects to address in modularity design for robots to find a practical and useful modular robot system using the present technology. It concerns module granularity, module scaling, hardware interface, and joint structure. The most suitable module granularity is on the simplified function level, where each module is self-contained, independent unit and the joint modular group consists of only joints with 1-DOE The modular manipulators can effectively achieve many tasks in practical applications without scaling on either joints or links, but with a common standard hardware interface. Furthermore, the joint module should be able to achieve rotation and bending in a single joint module of 1-DOE We propose a new design concept, TOMMS (TOshiba Modular Manipulator System), to produce a modular manipulator system that can be assembled into any desired configuration to provide adaptability to tasks, using a few kinds and types of modules as possible, without the weed for special handling such as modification of control software. A trial system, TOMMS-1, was developed to study the design of the hardware and software for TOMMS.
