To automate the wiping task using robots, it is crucial to endow the robot with the capability to maintain desired contact with target surfaces. However, challenges arise when geometric priors and visual feedback are not available or when detailed object information is needed. In this paper, a tactile-guided hybrid pose/force control scheme based on gain-scheduling proportional-integral-derivative (PID) is proposed to address these challenges. Leveraging a tactile sensor, three features are extracted from the tactile data and used in the control loop. The control scheme regulates the contact normal force on unknown surfaces with slowly changing curvature while following a trajectory on the surface. It also allows real-time adaptation of the desired contact force to varying surface conditions. The performance of the proposed scheme is evaluated on a robot manipulator equipped with a tactile sensor. Experimental results show that the proposed system can identify stains, guide itself to re-clean areas, and successfully accomplish the wiping task.

In this paper, an automatic vehicle speed controlsystem with PID controller and Kalman filter is designed with consideration of various uncertainties, such as disturbance, system variation and feedback sensor noise, and then verified through computer simulations. The performance degradation due to disturbance and system variation in the basic open-loop control is shown. To resolve this problem, a PID controller based feedback system is designed for the automatic vehicle speed controlsystem. In addition, to improve the performance degradation due to feedback sensor noise that may occur during the feedback process, the Kalman filter is applied for the automatic vehicle speed controlsystem. Ultimately, it is verified that the designed automatic vehicle speed controlsystem with PID controller and Kalman filter not only satisfies all performance criteria but also has the ability to reject disturbance, cope with system variation and reduce feedback sensor noise.

One of the remarkable features of the human tactile system is the perception of slippage over a diverse range of object dimensions, weights, shapes, textures, and stiffness. advanced prosthetics strive for more natural and intuitive performance, hence slippage anticipation and prevention being indispensable for an artificial hand. Numerous sensor and circuit topologies have been used in the state-of-the-art. Multi-modal sensor integration for static and dynamic measurements, complex design, wearability, sensitivity, hysteresis, and cost are still the significant challenges faced. In this work, a simple, low-cost, flexible thread-based resistive strain/force sensor is fabricated and interfaced with a current source excitation-based resistance measurement circuit. The sensor exhibits excellent performance for slip detection by showing selectivity to the static and dynamic measurements corresponding to the event of initial object contact and slippage instances, respectively. The proposed circuit topology promises better sensitivity, resolution, and baseline resistance compensation, leveraging the system's effectiveness for slippage detection. Experimental result shows the sensor can measure a displacement as small as 0.1 mm. This method can generate further control actions for slippage prevention thereafter.

This work outlines the development of a sophisticated and automated hydroponic systemcontroller to promote hydroponics, a soil-free crop-growing technique. The system regulates fertilizer and water distribution accurately using a range of sensors like as pH, water level, temperature, humidity, and Total Dissolved Solids (TDS), assuring long-term crop development. The Arduino analyses sensor data in real time to make informed changes, and a web application enables users to monitor and control the system remotely. Thanks to platform-independent technology, the system may be adapted to any hydroponics arrangement, giving farmers more flexibility. This interdisciplinary work combines hardware and software components to showcase a comprehensive approach to farming. The findings show that the developed platform-independent hydroponic systemcontroller is feasible and effective for boosting crop cultivation precision and efficiency, paving the way for more sustainable and technologically advanced agriculture.

In this research we have studied the performance of two NUI interfaces for the control of a robotic arm for EOD tasks, the Leap Motion contactless sensor and the Novint Falcon haptic device were used to control the Dobot Magician 5 of degrees of freedom robotic arm. Participants used both systems to simulate Pick and Place tasks, with different objects emulating suspicious packages, this being the most common task when using robotic systems for explosive ordnance disposal. The evaluations considered include placement accuracy, percentage of failures and/or collisions, completion time, mental workload and usability. The results obtained show that the Novint Falcon controller presents a lower mental workload, higher usability and a significant improvement in the performance to perform the proposed tasks, achieving a task completion effectiveness of 96% compared to the Leap Motion sensor-based interface with 77.42% effectiveness.
