“…In both cases, there is a small dead spot near the sensing element. Typical O-ToFtechnology used, e. g. [20], [21], can work up to a distance of 4 m, depending on the component used, but this extended range has the cost of having a relatively large dead spot of 10 cm in front of the sensing element. Similarly, the O-Tri-Type sensor used in [84], [85] has a detection range of 1.5 m and a dead spot of 20 cm.…”

“…Collision avoidance on a mobile robot based on capacitive proximity sensing for a variety of materials was shown in [17]. Covering robot links with modular single-ended capacitive proximity (C-SE) skins for collision avoidance and HRI is proposed in [18], [19], [20], [21]. These works show the potential for these technologies, especially for HRI.…”

“…However, for example in [19], it is discussed that C-SE is not suitable enough to detect insulating materials for the intended application of collision avoidance. As a solution, in [20], [21], a combination with time-of-flight (O-ToF) sensing (see Sec. III-B4) is proposed to compensate for the shortcomings of C-SE sensors.…”

A major task in motion planning is to find paths that have a high ability to react to external influences while ensuring a collision-free operation at any time. This flexibility is even more important in human-robot collaboration since unforeseen events can occur anytime. Such ability can be described as mobility, which is composed of two characteristics. First, the ability to manipulate, and second, the distance to joint limits. This mobility needs to be optimized while generating collision-free motions so that there is always the flexibility of the robot to evade dynamic obstacles in the future execution of generated paths. For this purpose, we present a Rapidly-exploring Random Tree (RRT), which applies additional costs and sampling methods to increase mobility. Additionally, we present two methods for the optimization of a generated path. Our first approach utilizes the built-in capabilities of the RRT*. The second method optimize the path with the stochastic trajectory optimization for motion planning (STOMP) approach with Gaussian Mixture Models. Moreover, we evaluate the algorithms in complex simulation and real environments and demonstrate an enhancement of mobility.

Cooperative robots that perform safety functions as part of cooperative work with humans have been recently drawing attention. Proximity and tactile sensors that can be retrofitted to a robot's surface are important safety measures for existing robots that are not manufactured as cooperative robots to be used as cooperative robots. In this paper, a string‐like self‐capacitance‐based proximity and tactile sensor that can be easily wrapped around various types of existing robots is proposed. The novel and useful point in this paper is that it can be easily mounted on various robots by a flexible string‐like proximity and tactile sensor. The sensor module can be adjusted to the required length by connecting different numbers of modules depending on the mounting surface. As a demonstration, six prototype sensor modules were connected by each connector and wrapped around a robotic arm. The sensor modules on the robot's surface could detect an object within its proximity range and detect the rough pressure after contact. In addition, the robotic arm with the sensor modules could be controlled in real time using the data obtained from the sensor that are object detection data at proximity range. These results confirm that the proposed sensor module can be used in the proximity and tactile sensors of existing robots. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
