“…First is introduced the KertrolBot [26], as is showed on 1(d), a small size micro-controller-based robot which is propelled by a differential locomotion, is equipped with infrared sensors, and disposes of Wi-Fi communications. The goal of the KertrolBot is to provide solutions for small applications due to simplicity of its design and the low computational power.In the second case the Yet Another Intelligent Robot (YAIR), as can be observed in 1(c) [5], offers a similar locomotion but disposes of a bigger structure in which are integrated a screen, some more sensors as a camera or a laser range sensor, and the use of a computer as main operational unit. The YAIR offers a more wide range of applications because of its advanced capabilities and its computing power.…”
