Voice recognition and command technology for applications with industrial robots is a relatively new field in the intelligent manufacturing industry. It offers a number of advantages over other methods of communication with robots, as it requires fewer specialized skills to manipulate the robot workstation. Additionally, using voice commands can help reduce the number of industrial injuries caused by contact with machinery, thus potentially save operators' lives in emergency situations where external assistance is not immediately available. This study presents a design of a Cartesian robot workstation which is equipped with a voice recognition system controlled by audio commands, as well as a vision perception system. The vision perception system uses the Real Sense depth camera that captures information about the coordinates of the work pieces, which is processed by SSD algorithm. The voice recognition system has been developed with an algorithm which combines both LSTM and HMM, and it has good performance in term of both efficiency and accuracy in controlling normal operation as well as emergency stop for our robot grasping workstation.

Typically, universities with a focus on technical sciences provide courses where students have to design control systems, to implement these control systems on embedded hardware and to verify the functionality of their implementations. Hence, the students work in groups and implement practical demonstrators based on given problem statements. In order to design, implement, and test robotic applications, it is mandatory to utilize expertise within the field of robotics and the field of embedded systems. The combination of expertise within both fields (robotics and embedded systems) is a highly demanded skill set, which is required to work for companies with focus on aviation, automotive, and even emerging applications for agricultural technology. The technical complexity of these applications is increasing almost exponentially, which requires abstract model-based approaches to ease the design flow of such implementations. This paper introduces a model-based approach for students within robotics and/or embedded systems degree programs. Moreover, this paper describes the state-of-the-art workflow to implement problem statements within the field of robotics and embedded systems (tools, approach and test), gives and overview of the model-based approach for students within these field of applications, and shows the integration of the results into courses based on a control system model.
通常,专注于技术科学的大学提供的课程中,学生必须设计控制系统,在嵌入式硬件上实现这些控制系统,并验证其实现的功能。因此,学生在小组中工作,并根据给定的问题陈述实施实际演示。为了设计、实现和测试机器人应用程序,必须利用机器人和嵌入式系统领域的专业知识。这两个领域(机器人和嵌入式系统)的专业知识的结合是一项非常需要的技能,这是为专注于航空,汽车甚至新兴农业技术应用的公司工作所必需的。这些应用程序的技术复杂性几乎呈指数级增长,这需要抽象的基于模型的方法来简化此类实现的设计流程。本文为机器人和/或嵌入式系统学位课程的学生介绍了一种基于模型的方法。此外,本文描述了在机器人和嵌入式系统(工具、方法和测试)领域实现问题陈述的最先进的工作流程,为这些应用领域的学生提供了基于模型的方法的概述,并展示了将结果集成到基于控制系统模型的课程中。

Though several approaches exist to automatically generate repair parts for fractured objects, there has been little prior work on the automatic assembly of generated repair parts. Assembly of repair parts to fractured objects is a challenging problem due to the complex high-frequency geometry at the fractured region, which limits the effectiveness of traditional controllers. We present an approach using reinforcement learning that combines visual and tactile information to automatically assemble repair parts to fractured objects. Our approach overcomes the limitations of existing assembly approaches that require objects to have a specific structure, that require training on a large dataset to generalize to new objects, or that require the assembled state to be easily identifiable, such as for peg-in-hole assembly. We propose two visual metrics that provide estimation of assembly state with 3 degrees of freedom. Tactile information allows our approach to assemble objects under occlusion, as occurs when the objects are nearly assembled. Our approach is able to assemble objects with complex interfaces without placing requirements on object structure.
虽然有几种方法可以自动生成断裂物体的修复部件,但对于生成的修复部件的自动组装,以前的工作很少。由于断裂区域具有复杂的高频几何结构,对断裂修复部件的装配是一个具有挑战性的问题,这限制了传统控制器的有效性。我们提出了一种使用强化学习的方法,该方法结合了视觉和触觉信息来自动组装断裂物体的修复部件。我们的方法克服了现有组装方法的局限性,这些方法要求对象具有特定的结构,需要在大型数据集上进行训练以推广到新对象,或者要求组装状态易于识别,例如用于钉入孔组装。我们提出了两个视觉指标,提供装配状态的估计与3个自由度。触觉信息允许我们的方法在遮挡下组装物体,就像物体接近组装时发生的那样。我们的方法能够组装具有复杂接口的对象,而无需对对象结构提出要求。

In this paper, a nonlinear model predictive control considering vehicle jerk dynamics is proposed for improving ride comfort of passengers. Since the vehicle model in prediction phase requires high accuracy dynamics in order to handle the jerk motion, the approximated wheel load transfer dynamics is introduced. Also, to obtain the control capability for not only jerk but also acceleration, velocity and position, the expanded state space model including these dimensions into the one has been developed. It improves the utility as autonomous vehicle controller. By numerical simulation in assuming cornering driving scene, the effectiveness that jerk and other vehicle states enable to constraint simultaneously by individual torque distribution by electric power train is validated. Further, the principle of the optimized torque distribution by proposed method is analyzed.
为了提高乘客的乘坐舒适性,本文提出了一种考虑车辆抖动动力学的非线性模型预测控制方法。由于预测阶段的车辆模型需要较高的动力学精度来处理突跳运动,因此引入了近似的轮载传递动力学。同时,为了获得系统对加速度、速度和位置的控制能力,建立了包括加速度、速度和位置在内的扩展状态空间模型。提高了自动驾驶汽车控制器的实用性。通过数值模拟,验证了在假设转弯驾驶场景下,电动传动系统的个别转矩分配同时约束车辆制动和其他状态的有效性。进一步分析了该方法优化转矩分配的原理。

The aim of this study is to develop an algorithm for task assignment and movement planning to a destination by considering the acceleration and deceleration patterns of automated guided vehicles (AGVs). In this study, we propose an algorithm for task assignment and motion planning for AGV kinematics with multiple search trees based on the conflict-based search with optimal task assignment (CBS-TA) of Hönig et al. By devising the options for AGV actions and settings for standby actions, the algorithm can perform optimal motion planning for each AGV, considering its dynamic characteristics.

The Estimation of Ocean-current Velocity for AUV Using Optimization-Based Alignment 基于优化对准的水下航行器海流速度估计

Doppler velocity log (DVL) can provide velocity information for the strap-down inertial navigation system (SINS), and it is widely used in the field of navigation for autonomous underwater vehicles (AUVs). However, in deep-sea scenarios, the DVL's output is the velocity relative to the ocean currents since it works in the water-tracking mode. The ocean-current velocity brings systematic errors to the SINS/DVL integrated navigation system, which leads to the degradation of navigation positioning accuracy. Therefore, estimating and compensating for the current velocity is an essential requirement for high-precision navigation performance and an important topic for oceanographic research. In the small ocean area where AUV works, the current velocity remains stable for a short time, and it can be considered a constant value. This paper proposes an optimization-based alignment (OBA) method for estimating the ocean-current velocity based on the GNSS (global navigation satellite system)/SINS/DVL integrated system. The simulation results show that the proposed method can estimate the current velocity accurately and does not depend on the initial value compared with the traditional KF method.
多普勒速度日志(DVL)可以为捷联惯性导航系统(SINS)提供速度信息,广泛应用于自主水下航行器(auv)的导航领域。然而,在深海场景中,DVL的输出是相对于洋流的速度,因为它是在水跟踪模式下工作的。海流速度给SINS/DVL组合导航系统带来系统误差,导致导航定位精度下降。因此,海流速度的估计与补偿是实现高精度导航的基本要求,也是海洋研究的重要课题。在AUV工作的小海域,流速在短时间内保持稳定,可以认为是一个恒定值。提出了一种基于全球导航卫星系统(GNSS)/SINS/DVL组合系统的海流速度估算优化对准方法。仿真结果表明,与传统的KF方法相比,该方法可以准确地估计出当前速度,并且不依赖于初始值。

A specified device or laser tracker accurately calibrates robot joints' offsets, but they require bothering setup for daily calibration. The offset calibration using a hand-eye camera and a marker makes it more convenient. However, the calibration accuracy reduces according to the limitation in pose estimation accuracy using a hand-eye camera and a marker. This paper proposes a method for optimizing the camera poses to capture the marker in joint offset calibration using a hand-eye camera to increase the calibration accuracy. We proposed an index to evaluate the effect of the error in the pose estimation based on the camera images on the offset calibration. The offset calibration with the marker measurement at the poses, which obtained the optimization to maximize the proposed index, realized higher accuracy than other approaches.

In some cases, it is necessary to restrict the movement of these robots to certain areas or rooms during specific times or for specific tasks, in order to ensure safety and prevent interference. Traditional methods for creating virtual walls and borders to accomplish this often have limitations in terms of ease of use, universality, and remote accessibility. In order to overcome these issues, this work presents a method for creating virtual walls, doors, and borders using the Robotic Operating System (ROS) and point cloud data. This method can be used to restrict the movement of autonomous mobile robots in human-centered environments, including smart homes and warehouses, and can be activated and deactivated remotely. It is a flexible and cost-effective solution that does not require specialized sensors and can be used with single or multi-robot systems. The effectiveness of our method has been demonstrated through testing in simulation based on the reconstruction of real environments.
自主移动机器人正在智能家居和工业中成为一种常见的景象,它们被用于清洁和物料搬运等任务。在某些情况下,为了确保安全和防止干扰,有必要在特定时间或特定任务期间限制这些机器人在特定区域或房间的运动。用于创建虚拟墙和边界以完成此任务的传统方法通常在易用性、通用性和远程可访问性方面存在局限性。为了克服这些问题,这项工作提出了一种使用机器人操作系统(ROS)和点云数据创建虚拟墙、门和边界的方法。这种方法可以用来限制自主移动机器人在以人为中心的环境中的运动,包括智能家居和仓库,并且可以远程激活和停用。它是一种灵活且经济高效的解决方案,不需要专门的传感器,可以与单个或多个机器人系统一起使用。基于真实环境重建的仿真实验验证了该方法的有效性。
