Home service robots must have implements like conversation interfaces so it can be easily accepted by the users. To get basic data to develop such a robot, we investigated the robot's impressions of when it responded to the instructions of operating a TV or when it planning the cooking recipes. Thirty men and thirty women of different age groups rated the impression on using the robot. The results indicated that we should find a better way to inform to the user when a word was not in the robot's database. Moreover, we should reconsider what kind of the robot's gesture the users need. In addition, the embodiment of the robot made the impressions better. In addition, women judged the robot positively probably because the robot had a cute appearance.

This paper discusses the scale-dependent grasp. Suppose that an object is initially placed on a table without touching by human hand and, then he (or she) finally achieves an enveloping grasp after an appropriate approach phase. Under such initial and final conditions, human unconsciously changes the grasp strategy according to the size of object, even though they have similar geometry. We call the grasp planning the scale-dependent grasp. Focusing on column objects, we first classified the grasp patterns into a couple of grasps and extracted the essential motions so that we can apply the scale-dependent grasp to multi-fingered robot hands. We found that the grasp patterns should be also changed according to the surface friction and the geometry of cross section of object in addition to the scale. The basic strategies were verified by experiments. Finally, we considered how each strategy should be switched from one to another.

The self-reproduction capability of machines can enhance manufacturing efficiency and contribute to reliability since it enables the machines to fabricate themselves in geometric progression while testing their functionality through the reproduction process. In addition, a part of the process can be utilized as a self-repair process. This paper discusses the method of its realization on the basis of machines composed of identical autonomus cells. The proposed concept includes the specialization of cells according to their positions, growing in size by capturing new cells, transferring genetic data to the new cell, and splitting into two independent halves after grown up. Experiments have demonstrated the self-reproduction of mobile machines each of which is composed of multiple cells connected one another in a row, one-dimensionally.

A 6 legged walking vehicle composed of a pair of leg units each of which has three expandable soles and has an ability to make rotational and traversable motion among the leg units is made. It is developed to realize a solid and reliable walking vehicle for practical uses in the near future with spread mechanical elements used in usual hydraulic construction machines. It weighs about 80 [kg] with all aluminum (including honeycomb frame) structure. Owing to mounted 24 [V] /12 [Ah] battery unit and wireless control system, it has no umbilical cord for power supply, control and communication. It is shown by the experiments that the vehicle can walk continuously over 1 hour, crossing many obstacles those maximum height is about 0.9 [m], and many irregular soil terrain.

This paper proposes a planning method for time-optimal trajectories of mobile robots. A dynamical model for two independently driven wheels type mobile robots is derived. Using an idea of path parameter, optimal trajectory for specified path of mobile robot is easily obtained considering dynamical constraints such as driving torques and velocities. An efficient collision-free near-time-optimal trajectory planning method is proposed using a local optimization method and a global search method of initial paths. The B-spline parameter optimization method is used as a local optimization. Some numerical examples show an effectiveness of the proposed planning method.

Autonomous walking machines are generally required in dangerous situation in which humankind cannot step. Thus, walking machines have to return to the base position by themselves, even if a leg is injured by some accidents. In such a case, hexapod walking machine has advantages, because it can keep walking by remained five legs. This paper proposes a new gait rule named injury-adaptive wave gait. The new gait is available for not only normal hexapod walking, but also injured hexapod walking. Additionally, to apply the new gait rule smoothly, we propose a new control strategy for leg motion control. The strategy uses a notion of distributed control to realize synchronized motion among six legs. By combination of the gait rule and the control strategy, walking machine can realize suitable gait for its walking condition.

To realize intelligent robot, it is necessary to establish an effective method for visual and tactile recognition. Much of the existing work on tactile recognition has assumed that tactile sensors derive only data on object surfaces so as to generalize recognition algorithm. With tactile sensors which provide local features of contact areas, e. g, vertex, edge, etc., it is possible to prune inconsistent interpretations more effectively than existing methods.This paper proposes a method for object identification using local feature sensors. In the method, interpretations at each step of identification process are represented as a set of subsets of 3-D space where a sensor to be located. With the progress of identification process, the set will be narrower. Consequently local constraints become strict and inconsistent interpretations will be efficiently pruned. In the pruning, local constraints are compared considering the error bounds of measurement in sensor data.
