AbstractThe article presents the possibilities of using easily accessible and inexpensive educational sets in scientific research and the process of robotics education. Such kits allow the exploration of theoretical and practical knowledge taking into account aspects of engineering, such as: mechanics, drive systems, sensor systems, control and programming of robots. Models of robots built from inexpensive components can also be used to test new solutions in the field of construction or control algorithms before they are used in real applications. As an example, the model of the palletizing manipulator for self-assembly was shown, the control of which was based on the Arduino Uno controller, while the drives were implemented using low-cost hobby-grade servos. For the kinematic structure of this manipulator, the forward and inverse kinematics task for the position has been discussed. This constituted the basis for the development of a manual control algorithm implemented in the controller – using a joystick and programmed – based on the data sent to the controller using serial communication from a PC. The article presents the results of the computer simulation of the manipulator kinematics, the hardware and software implementation of the robot model and the effects of its operation. The possibility of expanding the control system with additional elements to increase its functionality was indicated.

This paper presents new low-cost systems for the automation of some fish farm operations. Particularly, computer vision is applied to non-contact fish weight estimation. Stereo vision systems with synchronised convergent cameras are employed to perform fish 3-D segmentation in tanks and sea cages. Several pre-processing algorithms are applied to compensate for illumination local variations. The approach applied for fish 3-D segmentation consists in detecting in both images certain fish features. Once these points have been detected and validated in both images, the fish are 3-D segmented by applying stereo vision matching considerations. Fish weight is estimated by using simple length-weight relations well known in the aquaculture domain. The paper also briefly describes robotics systems for fish feeding and underwater pond cleaning, which can be also used to implement the above mentioned computer vision techniques for the fish estimation.

The dynamic analysis and control of flexible robot manipulators have been the main concerns of many recent studies in aeronautics and robotics. Moreover, the complexity of this problem increases when a flexible manipulator carries a payload. In this paper, we proposed a space two-link flexible manipulator with tip payload featuring surface-bonded piezoelectric torsional actuator and shear actuator. The equations of motion for the system are obtained using Hamilton’s principle. A Lyapunov-based controller is proposed to suppress the vibration of the system. Stability of the system is also investigated. The simulation results demonstrate the proposed control strategy is well suited for active control of vibration suppression on flexible manipulators.

This paper presents the details of a compact embedded-computing module designed to meet a variety of pedagogical objectives within mechatronics, controls, and robotics. Built around an ATmega32U4 microcontroller, the 1.8 × 4.0 centimeter module has flash memory for program and data storage, 25 general-purpose input/output lines, four timer/counters, 12 channels of 10-bit analog-to-digital conversion, and support for a variety of serial communications protocols, including USB. The unit adapts easily to a solderless breadboard for quick prototyping, and requires only an external 5-volt power source for operation. Furthermore, it can be programmed directly over a USB connection to a computer, thereby eliminating the need for a separate programming device. As a member of the AVR family of microcontrollers, the development tools for the processor are freely available for Windows, Mac, and Linux. When assembled in sufficient quantity, the part cost for each module is approaching $10US, making it a low-cost solution for a variety of tasks. To enable students and professors to explore both the module and the host of application principles, we have chosen to post the design files and documentation on a publicly-accessible wiki, leaving room for collaborative improvements and the sharing of technology with other educational institutions.

In our day to day, technology and robotics are increasingly present. Currently, Information and Communication Technologies (ICT) are undergoing a vertiginous development and this is affecting practically all fields of our society and education is no exception. On the other hand, the incorporation of robotics in the classroom aims to promote learning experiences where students acquire and develop skills to solve specific problems, which allow them to acquire new knowledge and give answers to the changing environment of today’s world. This article presents the progress in the development of a project where robotics is implemented for the teaching of mathematics in preschool and first grade students; three public schools were selected for this purpose, and a series of playful educational activities were developed, using low cost robotic tools.

ABSTRACT: In this study was developed a three-dimensional robotic device, equipped with a system of actuators, sensors, and controllers to do the individual irrigation of plants in low-cost greenhouses for family farming. After the development were carried out the data collection in the field. In the data analyzing, reported that there was no statistical difference between means for manual irrigation and robotics in the development of agronomic variables of stem height, stem diameter and number of leaves, concluding that the robotic irrigation promoted a lower coefficient of variation and a lower standard deviation in the samples.
