The article describes the prerequisites for the use of educational robotics in the school course of informatics, the history of the development of its directions and the normative basis for its use in modern school education. A typical model of an educational robotic project for the organization of research and project activities of students has been proposed. The technological chart of the lesson as an example of the implementation of a robotic project in the framework of the research activities on informatics is considered. Approaches to the organization of educational activities, teaching tools and ways of evaluation in informatics class on the theme “Information processes. Information transmission” when using the project approach are described.

<em>This study aims to determine the application of PjBL model based on simple props and critical thinking skills of students in the School Laboratory course. This research uses research type Pre-Experimental Design with sample of all students of semester II which programmed Laboratory School on even semester 2016/2017 in </em><em>Program Studi Pendidikan Fisika Fakultas Keguruan dan Ilmu Pendidikan Universitas Papua. The results showed that the props designed by students 74.0% ± SD 4.2 or are in a good category. Assessment of practical worksheet covers the aspect of format, content, language/writing, and benefits/functions obtained 80.3% ± SD 7.4 or are in the very good category. Critical thinking skills of the students during the learning that is 66.7% ± SD 4.9 or are in a good category. Therefore the application of PjBL learning based on simple props can be used to develop critical thinking skills.</em>

Abstract In the literature on mission-oriented innovation supply side and tech-oriented approaches have been complemented by broader and more inclusive societal approaches. Here, it is highlighted that both directionality and broad anchoring of diverse stakeholders across private, public, and civic domains are key to successful implementation. Still, it is unclear how these dimensions relate and unfold in practice. Using digital literacy in education as an example of mission-oriented innovation, this paper investigates what prerequisites and capabilities are needed to envision and govern such processes. Based upon a case study of innovative teaching practices in twenty-five classes at ten primary schools in Norway, the paper finds that the motivation, dedication, and engagement of the teachers is not primarily related to the digital technologies themselves, but to the professional and pedagogical anchoring of the digital teaching tools. The mobilization of the professionalism of the teachers is enabled by a process of balanced empowerment.

This paper shows the design and modeling of an end effector with a bidirectional telescopic mechanism to allow a surgical assistant robot to hold and handle surgical instruments. It also presents a force-free control algorithm for the direct teaching of end effectors. The bidirectional telescopic mechanism can actively transmit force both upwards and downwards by staggering the wires on both sides. In order to estimate and control torque via motor current without a force/torque sensor, the gravity model and friction model of the device are derived through repeated experiments. The LuGre model is applied to the friction model, and the static and dynamic parameters are obtained using a curve fitting function and a genetic algorithm. Direct teaching control is designed using a force-free control algorithm that compensates for the estimated torque from the motor current for gravity and friction, and then converts it into a position control input. Direct teaching operation sensitivity is verified through hand-guiding experiments.
