Programming and robotics are critical thought-provoking concepts that shape STEM courses within secondary schools today. Their use in creating engaging, skill-building projects in technology education is constantly increasing worldwide. In this work, a novel learning scenario aiming at the design of 3D bioclimatic spaces is proposed. It combines Arduino microcontroller with 3D printing devices. The scenario is appropriate for the last grades of P-12 students and can be easily implemented in every secondary high or vocational school. It is fully compliant with most national ICT curricula adopted. The main objective is that students will enhance their critical thinking capacity, increase the level of digital literacy, and develop design skills by exploring and constructing appropriate 3d space models.

The last decade has seen a flowering of applications driven by brain–machine interfaces (BMIs), particularly brain-actuated robotic devices designed to restore the independence of people suffering from severe motor disabilities. This review provides an overview of the state of the art of noninvasive BMI-driven devices based on 86 studies published in the last 15 years, with an emphasis on the interactions among the user, the BMI system, and the robot. We found that BMIs are used mostly to drive devices for navigation (e.g., telepresence mobile robots), with BMI paradigms based mainly on exogenous stimulation, and the majority of brain-actuated robots adopt a discrete control strategy. Most critically, in only a few works have disabled people evaluated a brain-actuated robot. The review highlights the most urgent challenges in the field, from the integration between BMI and robotics to the need for a user-centered design to boost the translational impact of BMIs. Expected final online publication date for the Annual Review of Control, Robotics, and Autonomous Systems, Volume 4 is May 3, 2021.

Education plays an important role in producing people who can make changes by producing ideas in learning. However, the current problem is the readiness of graduates from schools to be able to continue their survival in finding work. One of them is the lack of skills possessed by graduates of high school/vocational school at this time and also very high competitiveness in getting a job. At present the workforce with graphic and multimedia design skills has considerable opportunities in industries engaged in digital printing printing services. The solution offered is to improve the skills of high school/vocational graduates through digital printing training and marketing their products online.

The Future

We are now living in digital age. Almost all activities are carried out using digital technology devices. Various information and knowledge are saved in digital devices. Therefore, anyone who lives in the present and the future should have adequate digital literacy. This study aims to determine the level of digital literacy, future time perspective, and the self-confidence of prospective vocational school graduates in entering the job market. In addition, this study also intends to answer whether there is an influence of digital literacy and future time perspective on the self-confidence of prospective vocational school graduates entering the job market. This research revealed that the digital literacy level of prospective vocational school graduates is at a moderate level, the future time perspective is at a good level, and the level of self-confidence entering the job market is at a good level. Mediated by a future time perspective, digital literacy indirectly affects the self-confidence of prospective vocational school graduates in entering the job market. There is no significant relationship between digital literacy and confidence in entering the job market. Thus, digital literacy--future time perspective--self-confidence in entering the job market is a pathway used to prepare prospective vocational school graduates to enter the job market. Vocational schools are directed to develop real programs to increase students' digital literacy to encourage the growth of self-confidence of prospective vocational school graduates in entering the job market.

Behavioural Evidence

A puzzle for neuroscience - and robotics - is how insects achieve surprisingly complex behaviours with such tiny brains1,2. One example is depth perception via binocular stereopsis in the praying mantis, a predatory insect. Praying mantids use stereopsis, the computation of distances from disparities between the two retinas, to trigger a raptorial strike of their forelegs3,4 when prey is within reach. The neuronal basis of this ability is entirely unknown. From behavioural evidence, one view is that the mantis brain must measure retinal disparity locally across a range of distances and eccentricities4–7, very like disparity-tuned neurons in vertebrate visual cortex8. Sceptics argue that this “retinal disparity hypothesis” implies far too many specialised neurons for such a tiny brain9. Here we show the first evidence that individual neurons in the praying mantis brain are indeed tuned to specific disparities and eccentricities, and thus locations in 3D-space. This disparity information is transmitted to the central brain by neurons connecting peripheral visual areas in both hemispheres, as well as by a unilateral neuron type. Like disparity-tuned cortical cells in vertebrates, the responses of these mantis neurons are consistent with linear summation of binocular inputs followed by an output nonlinearity10. Additionally, centrifugal neurons project disparity information back from the central brain to early visual areas, possibly for gain modulation or 3D spatial attention. Thus, our study not only proves the retinal disparity hypothesis for insects, it reveals feedback connections hitherto undiscovered in any animal species.

Over the last decade, eye tracking systems have been developed and used in many fields, mostly to identify targets on a screen, i.e. a plane. For novel applications such as the control of robotic devices by the user vision, there is a great interest in developing methods base on eye tracking to identify target points in free three dimensional environments. The objective of this paper is to characterise the accuracy the eye tracking and computer vision combination that was designed recently to overcome many limitations of eye tracking in 3D space. We propose a characterization protocol to assess the behavior of the accuracy of the system over the workspace of a robotic manipulator assistant. Applying this protocol to 33 subjects, we estimated the behavior of the error of the system relatively to the target position on a cylindrical workspace and to the acquisition time. Over our workspace, targets are located on average at 0.84 m and our method shows an accuracy 12.65 times better than the calculation of the 3D point of gaze. With the current accuracy, many potential applications become possible, such as visually controlled robotic assistants in the field of rehabilitation and adaptation engineering.

Information technology and robotics have been integrated into interventional medicine for over 25 years. Their primary aim has always been to provide patient benefits through increased precision, safety, and minimal invasiveness. Nevertheless, robotic devices should allow for sophisticated treatment methods that are not possible by other means. Several hundreds of different surgical robot prototypes have been developed, while only a handful passed clearance procedures, and was released to the market. This is mostly due to the difficulties associated with medical device development and approval, especially in those cases when some form of manipulation and automation is involved. This chapter is intended to present major aspects of surgical robotic prototyping and current trends through the analysis of various international projects. It spans across the phases from system planning, to development, validation, and clearance.

It so happens that microcontrollers tend to get heated by immense temperature effects due to environmental changes and disturbances. Many microcontrollers have thermal temperatures ranging from 10 °C to 50 °C. In this study, design and thermal analysis of microcontroller are presented where systems operate on ARDUINO microcontroller. Microcontrollers are used for automation and robotics applications. Various industrial applications can use this microcontroller in the future by using IoT principles. Hence, there is a need for thermal analysis of the microcontroller. Arduino UNO is taken for study. The effect of various factors such as thickness and length of PCB were studied. Throughout the study, it was observed that there is a 50-60% achievement in heat dissipation with the modified microcontroller.
