Humanoid robots have evolved over the years and today it is in many different areas of applications, from homecare to social care and healthcare robotics. This paper deals with a brief overview of the current and potential applications of humanoid robotics in healthcare settings. We present a comprehensive contextualization of humanoid robots in healthcare by identifying and characterizing active research activities on humanoid robot that can work interactively and effectively with humans so as to fill some identified gaps in current healthcare deficiency.

There have been a number of successful attempts in designing obstacle avoiding robots. These works differ by selection of sensors, path mapping process and the algorithms applied to set the operational parameters. In this paper we present a los cost ultrasonic distance sensor for obstacle avoidance for mobile robot navigation. The system is implemented using microcontroller Arduino Uno, a Wi-Fi module, an Arduino motor shield driver which controls the robot through the geared dc motors. The system showed good performance under various lighting conditions. Experimental results with varied positions of obstacle show the flexibility of the robot to avoid it and have shown a decent performance in our laboratory. The robot is additionally ready to acknowledge victims before it, the sensing element system is extremely low-cost as a result of it solely uses one distance sensing element.

As a result of the pandemic lockdown, most Faculty, Staff, and students in Nigerian universities were unable to learn online because of irregular power and internet unavailability. As a major concern to the Nigerian Deans of Engineering, a study was commissioned by the Deans to identify the extent of the problem with a view to identifying the research and development areas and proffer an indigenous solution to the problems identified. This paper discusses the results of an online survey administered during the lockdown to a stratified sample size from the over 80,000 engineering students' population in Nigeria. The initial results showed that there is need to develop some form of a costeffective but modular and mobile integrated boosted internetready power system suitable for teaching, learning and research which is always-on both day and night for learning.
