This research introduces an innovative approach to enhance the mobility and independence of individuals with limited mobility by developing an IoT-based, self-reliable wheelchair capable of climbing stairs. The wheelchair utilizes Atmega328 microcontroller as its central processing unit, incorporating an accelerometer to detect hand movements for intuitive control of forward, backward, left, and right motions. The unique triangular wheel arrangement on either side of the wheelchair enables it to navigate staircases effectively. Powering the wheelchair is a rechargeable battery, with a regulator ensuring a stable power supply to the boards and sensors. The H-bridge motor driver controls the wheelchair's motors, facilitating smooth and precise movements. In addition to its advanced mobility features, the wheelchair is equipped with health monitoring capabilities. A heartbeat and temperature sensor are integrated to continuously monitor the user's health condition. In the event of deteriorating health, an alarm is triggered, and a corresponding message is displayed on the LCD display. This real-time health monitoring system adds an extra layer of safety, ensuring timely intervention in case of emergency. This IoT-based wheelchair represents a significant advancement in assistive technology, providing not only enhanced mobility for navigating challenging terrains but also incorporating health monitoring features to ensure the well-being of the user. The integration of Atmega328 microcontroller, sensors, and motor control technologies showcases an intelligent approach to empower individuals with limited mobility.

Teleoperation allows robots to perform complex actions in tasks and environments where robot cognition and motion capabilities cannot support autonomy or where cooperation with humans is necessary. In this work, we present a teleoperation system for controlling the motion of a non-anthropomorphic robot arm through a natural user interface that tracks human movements through a single RGB-D visual sensor. A proportional-derivative (PD) controller is formulated to regulate robot end-effector commanded accelerations and to deal with the noisy and low-frequency human information. The system is integrated in the robot operating system (ROS) and a Universal Robots UR3 cobot is used for the evaluation. The results show that the PD controller achieves a superior performance in terms of both tracking accuracy and robot motion smoothness compared to using a proportional controller which regulates the commanded velocities. Furthermore, the same gains of the PD controller can be used to handle a wider range of human speeds. Finally, we provide real-time demonstrations of the system and the ROS pipeline.

Indoor Environmental Quality (IEQ) affects occupants' health, wellbeing and comfort, making its assessment increasingly required. This work presents a system designed to collect subjective and objective data on IEQ, referred to as PROMET&O (PROactive Monitoring for indoor EnvironmenTal quality & cOmfort). It is built on a survey and a low-cost and accurate multi-sensor device. The former was developed to collect feedback on occupants' comfort perception and personal and behavioural information. The latter was developed to monitor the thermal, lighting, acoustic and air quality conditions in indoor environments. The monitored parameters (air temperature, relative humidity, carbon dioxide, carbon monoxide, nitrogen dioxide, particulate matter, volatile organic compounds, formaldehyde, illuminance and sound pressure level) were selected based on international standards. A three-step calibration of the device is applied to ensure the measurements' reliability. The monitored data is transferred and processed on an open-source platform and the thermal comfort, visual comfort, acoustic comfort, indoor air quality and IEQ indexes are calculated and displayed on a user-friendly interface. This interface was designed to inform both building managers and occupants on IEQ trends and to provide them with more information on monitored parameters and hints on actions to improve their comfort. Preliminary tests in laboratory and in-field have shown the validity and scalability of the system's design.

In view of the characteristics of energy consumption in wireless sensor network nodes in the process of mechanical vibration detection, compression sensing technology (CS) was introduced. The system completed the sparse representation of the signal and the design of the orthogonal measurement matrix in the DSP of the terminal nodes. After wireless transmission of the measurement data to the coordinator node, with the help of CCSLink platform, it realized the reconstruction of the signal in the MATLAB environment. It was found that the sparse signal after DCT transformation had better sparsity, and the signal reconstructed by OMP algorithm had higher reconstruction accuracy. The introduction of compressed sensing technology not only reduced the data transmission capacity of wireless nodes, reduced the power consumption of data transmission, and also extended the life of nodes, which proved the feasibility of compressed sensing technology in the field of mechanical vibration monitoring.

Research shows that drivers rarely consult the vehicle owner's manual to learn to operate advanced safety features, like Adaptive Cruise control (ACC). Students from a United States university participated in a national competition, called EcoCAR Mobility Challenge (sponsored by the Department of Energy), to develop an engaging solution that is efficient and effective in educating drivers about the operation of ACC while adhering to user-centered design methodology. Students used an iterative design process and collected quantitative and qualitative data to evaluate the strengths and weaknesses of a mobile application. Iterations of the prototype included an interactive guide, video components, remote connection to the vehicle, and ultimately a solution that could reside on the vehicle's infotainment system. This paper details the process and evaluation outcomes and serves as a model for user-centered design of tutorials for advanced Driver Assistance systems (ADAS).
