The robots possess expansive application prospects in several fields, such as aerospace, national defense and military, space exploration, emergency and disaster relief, medical service, warehouse logistics, and so on. Since the legged robots possess notable advantages in terrain adaptability, motion flexibility and obstacle-crossing capability, many researchers have carried out the research upon the legged robots, including the biped robots [1]- [8], quadruped robots [9]- [16] and hexapod robots [17]- [25]. The research of the bionic robots can be found in [26], [27], imitating the exquisite structure, external shape, motion principle and behavioral way of living beings in nature. ...
This paper investigates the learning - based adaptive anti-coupling control issue for the robots under input and structural coupled uncertainties. In this paper, the input and structural coupled uncertainties are modeled and transformed into a system state related term, an internal state related term and a system input related term. With the aid of the actual exponential input-state stability and the dynamic auxiliary signal, the internal state related uncertainties can be suppressed. By utilizing the properties of the robot dynamics and several special nonlinear functions, the system state related uncertainties can be handled. Moreover, to overcome the system input related uncertainties, an indirect control law and the adaptive boundary estimation law have been designed. To simplify the control structure, the neural networks have been introduced as online approximators. Finally, a novel learning-based intelligent adaptive anti-coupling control structure has been established for the robots. The simulation results revealed the satisfactory control performance of the proposed anti-coupling control algorithm.
... Conati and colleagues (2018) further state that these four dimensions allow system designers to calibrate, at least in principle, pedagogically optimal designs and aim for a universal framework for interpretable AI and to understand better how to make machine learning-based models in supporting human learning and development at scale. However, it is likely that the actual interface of these systems will be related to how trust has been established -e.g., the development of humanoid robots (Huang et al., 2019). ...
Purpose
To help workers make the right decision, over the years, technological solutions and workplace learning analytics systems have been designed to aid this process (Ruiz-Calleja et al. , 2019). Recent developments in artificial intelligence (AI) have the potential to further revolutionise the integration of human and artificial learning and will impact human and machine collaboration during team work (Seeber et al. , 2020).
Design/methodology/approach
Complex problem-solving has been identified as one of the key skills for the future workforce (Hager and Beckett, 2019). Problems faced by today's workforce emerge in situ and everyday workplace learning is seen as an effective way to develop the skills and experience workers need to embrace these problems (Campbell, 2005; Jonassen et al. , 2006).
Findings
In this commentary the authors argue that the increased digitization of work and social interaction, combined with recent research on workplace learning analytics and AI opens up the possibility for designing automated real-time feedback systems capable of just-in-time, just-in-place support during complex problem-solving at work. As such, these systems can support augmented learning and professional development in situ .
Originality/value
The commentary reflects on the benefits of automated real-time feedback systems and argues for the need of shared research agenda to cohere research in the direction of AI-enabled workplace analytics and real-time feedback to support learning and development in the workplace.
The historical-technical development of the LARMbot humanoid is presented with its design and functional characteristics referring to low-cost and user-based laboratory solutions for applications with limited operational capabilities. The concept of the humanoid LARMbot has been developed since 2001 with the aim of aggregating design solutions and prototypes of partial robotic structures in manipulation and locomotion until reaching the conception of a unitary project still with a modular strategy for a high-performance functional laboratory prototype with innovative cable-actuated structures built in 2016. The latest developments have been published in improvements and expansion of parallel cable-actuated structures for the torso and also for the upper limbs to ensure high-load capacity compared to the weight of the LARMbot humanoid structure.
Due to the lack of accurate stability theoretical basis, the dynamic balance control of bipedal robots is a challenging topic. In this paper, we propose a controller that combines virtual model control and whole body control. In our framework, the whole system is simplified into a spring inverted pendulum model. Decoupling control is carried out for this model, and a virtual model is introduced to establish the relationship between the joint torque of the support leg and the state of the center of mass. The distribution of reaction force is obtained through decoupling closed-loop control. The whole body control part first uses multi task whole body control to determine the kinematics information, and then solves the joint feedforward torque through dynamical model, thus obtaining the desired force position hybrid control. Proposed algorithm improved the problem of incomplete decoupling between states and increased the stiffness of the support leg. The newly designed control framework was tested in Simscape dynamic simulation and verified the anti-interference ability and fast walking ability of Whole Body Balance Control for bipedal robots based on Virtual Model Control.
The LARMbot project intends to create a humanoid robot employing parallel mechanisms that are inspired by human anatomy. Solutions for humanoid arm are investigated combining the advantages of parallel and serial structures, as well as cable-driven architectures. A new solution has been designed for humanoid arm with a low-cost solution and user-oriented operation using commercial components and 3D printing manufacturing. Its feasibility is characterized by an analysis of operation performance via simulation whose reports are discussed also to suggest future improvements for construction and testing a prototype.KeywordsRoboticsHumanoidsDesignPerformance analysisSimulation
In this chapter an outline of History of Robotics is presented on how robot designs have been evolved with a special reference to mechanism designs.

A humanoid robot operated with position control has the characteristic of high trajectory tracking accuracy. However, its ability to adapt to complex environments is insufficient during walking due to the rigidity of the joint. More complex methods of control are needed when walking on uneven ground. A humanoid robot operated using torque control has strong robustness to complex environments or disturbance, but the flexibility of the joint makes its operation imprecise. The study of human motion reveals that the flexibility of the ankle joint allows people to walk in complex environments, such as uneven ground, with great stability. This paper presents a stable walking strategy for a humanoid robot based on ankle joint torque control. In this method, a humanoid ankle joint with two degrees of freedom is used for joint torque control. We describe a feed-forward torque calculation method and the setting of controller gain parameters. An algorithm compliant in the z-direction was designed for swinging legs. Finally, the BHR-6P model was used to simulate and verify the proposed algorithm.
This paper presents the historical development of the humanoid robots of the BHR series, ranging from the first Chinese humanoid robot BHR-1 to the current sixth generation BHR-6P. The early BIT (Beijing Institute of Technology) activities in robotics have laid a foundation for the development of the BHR series. The success of the first prototype of BHR-1 in 2001 gave the start of Intelligent Robot Institute and the technological and social influence attracted proper funding for continued development of the next BHR generations. Several challenges have been overcome by fully independent efforts of BIT, and future designs of the BHR series will aim at breaking through more challenging technological difficulties in the field of humanoid robotics.
