Autologous cartilage grafting during open airway reconstruction is a complex skill instrumental to the success of the operation. Most trainees lack adequate opportunities to develop proficiency in this skill. We hypothesized that 3-dimensional (3D) printing and computer-aided design can be used to create a high-fidelity simulator for developing skills carving costal cartilage grafts for airway reconstruction. The rapid manufacturing and low cost of the simulator allow deployment in locations lacking expert instructors or cadaveric dissection, such as medical missions and Third World countries. In this blinded, prospective observational study, resident trainees completed a physical simulator exercise using a 3D-printed costal cartilage grafting tool. Participant assessment was performed using a Likert scale questionnaire, and airway grafts were assessed by a blinded expert surgeon. Most participants found this to be a very relevant training tool and highly rated the level of realism of the simulation tool.

Due to the rapid development of technology, the use of numerically controlled machines in the industry is increasing. The main idea behind this paper is computer-aided design (CAD) based low-cost computer numerical control 2D drawing robot that can accurately draw complex circuits, diagrams, logos, etc. The system is created using open-source hardware and software, which makes it available at a low cost. The open-source LibreCAD application has been used for computer-aided design. Geometric data of a CAD model is converted to coordinate points using the python-based F-Engrave application. This system uses the Arduino UNO board as a signal generator of the universal g-code sender without compromising the performance. The proposed drawing robot is designed as a low-cost robot for educational purposes and aims to increase the student's interest in robotics and computer-aided design (CAD) skills to the next level. The drawing robot structure has been developed, and it meets the requirements of low cost with satisfactory experimental results.

Current and ongoing research and experimentations in the creation, design and build of low-cost, high-value prototypes for novel and unconventional interaction devices (IxD) in combination with cyber-physical system (CPS) (i.e. hybrid design tools (HDT), blended spaces) tangible user interfaces (TUI) and use of sensor technology lead to a variety of novel interaction modalities, experiences and possibilities. In line with this research, we propose a first prototype Human Sensor Selection Tool (HSST) as a preliminary guide and guidelines for design and engineering domains. The HSST is based on and inspired by the ‘five human senses’ [1], a plethora in human body signals (e.g. proprioceptive, vestibular) and gestures (e.g. facial expression, (e-)motions) that could be integrated, translated, transformed, adapted or mimicked to enhance and enrich the interaction modalities with for example computer-aided design (CAD), computer-aided technologies (CAx), and effectively affective CPS.

One of the major educators’ challenges is to teach the theoretical lessons with practical examples that can be taught in the classroom or teaching laboratories. The application of these examples will face a major problem for students in engineering: the difficulty of understanding and seeing how a mechatronic device works in everyday life. This requires the use of tools that enable the construction of different low cost prototypes to assist in student learning. Another challenge to educators is the need to motivate students during the lessons and to present models that students can make and develop on their own. Within this context this paper presents a pedagogic proposition based on the use of LEGO Mindstorms kits to teach practical lab activities in a mechatronics engineering course. The objective is to develop teaching methodologies with the use of these LEGO kits in order to motivate the students and also to promote a higher interdisciplinarity, by proposing projects that unify different disciplines. Thus, the paper is divided into three parts according to the educational experiences implemented in the course of mechatronics engineering at the Federal University of Uberlândia, Brazil. The first part presents the use of the kits in robotics discipline. The second part presents the use of the virtual kits in the Computer Aided Design discipline with zero-cost. The third part presents a multi-disciplinary project EDROM in mechatronics using LEGO kits.

AbstractThe lack of commercially available low-cost laboratory spraying equipment for testing microbial control agents can hinder advancement in the field of biocontrol. This study presents an inexpensive, portable sprayer that is calibrated utilizing laboratory consumables. The computer aided design files are made available so that it is freely modifiable and can be used for machine routing or 3D printing. Bioassay data was obtained by spraying Myzus persicae with spores of entomopathogenic fungi. Observed variation in droplet deposition within tested pressure and volume settings, and spore deposition within sprayed concentrations were low. Bioassay results show reproducible mortality for the tested doses.
