Smartphones have become increasingly prevalent in society, with over 45.5 million owned in the US in 2010. Research from Scranton University found that smartphones have had a positive effect on campus by improving communication and allowing ubiquitous access to school networks. While some argue smartphones could harm productivity or social engagement, the document concludes based on research that smartphones are an integral part of modern society and do not have an overall negative effect.

COVID-19 has put aside lots of children way from shcool. They need internet access to conintue their education. Government and Big Tech companies need to find a solution for 1.7 billion children without internet.
Inverse kinematics is an active research domain in robotics since several years due to its importance in several robotics application. Among the various approaches, differential inverse kinematics is widely used due to the possibility to real-time implementation. Redundant robotic systems exhibit more degrees of freedom than those strictly required to execute a given end-effector task, in such a case, multiple tasks can be handled simultaneously in, e.g., a task-priority architecture. This paper addresses the systematic extension of the multiple tasks singularity robust solution, also known as Null-space Based Behavioral control, to the case of set-based control tasks, i.e., tasks for which a range, rather than a specific value, is assigned. This is the case for several tasks such as, for example, mechanical joint limits of robotic arm as well as obstacle avoidance for any kind of robots. Numerical validation are provided to support the solution proposed.

In this paper, a decentralized control strategy for networked multi-robot systems that allows the tracking of the team centroid and the relative formation is presented. The proposed solution consists of a distributed observer-controller scheme where, based only on local information, each robot
estimates the collective state and tracks the two assigned control variables. We provide a formal stability analysis of the observer-controller scheme and we
relate convergence properties to the topology of the connectivity graph. Experiments are presented to validate the approach.
Coverage of a given area by means of coordinated autonomous robots is a mission
required in several applications such as, for example, patrolling, monitoring or
environmental sampling. From a mathematical perspective, this can often be
modeled as the need to estimate a scalar field, eventually time varying as in
the security applications. In this paper, the problem is addressed for the
challenging underwater scenario, where localization and communication pose
additional constraints. The solution exploits the appealing properties of the
Voronoi partition of a convex set within a probabilistic framework. In addition,
the algorithm is totally distributed and characterized by a strong engineering
perspective allowing the handling of asynchronous communication or possible loss
or adjunct of vehicles. Beyond the test in dozen of numerical case studies, the
algorithm has been validated by a challenging underwater test in 3 dimension
involving two Autonomous Underwater Vehicles (AUVs). The experiments were run in
the La Spezia harbor, in Italy, in February 2012 as demo
of the European project \co3auvs.
The paper presents an adaptive trajectory tracking control strategy for quadrotor Micro Aerial Vehicles. The proposed approach, while keeping the typical assumption of an orientation dynamics faster than the translational one, removes that of absence of external disturbances and of perfect symmetry of the vehicle. In particular, the trajectory tracking control law is made adaptive with respect to the presence of external forces and moments, and to the uncertainty of dynamic parameters as the position of the center of mass of the vehicle. A stability analysis as well as numerical simulations are provided to support the control design.
2. Smartphones Introduction. Smartphones have been a major up boost in our society today. Now the topic at hand is whether smartphones affect productivity, communication in the work place, social engagement, and education. Well its simple smartphones do not have that effect. Smartphones have improved life’s' in many ways through, internet access, instant messaging, media player, 3G video calling and a whole lot more.
3. Statistical Information Smartphones are continuing to improve as we speak, much more features are beginning to evolve. The proof is in the pudding, the demand for smartphones is increasing at such a rapid speed. So, according to Verein, S. (2009). Smart phones: how to stay clever in a downturn. Available at http://www.deloitte.co.uk/TMTPredictions/telecommunications/Smartphones-clever-in-downturn.cfm, over 45.5 million people in the United States owned smartphones in 2010 out of 234 million total subscribers. Despite the large increase in smartphone sales in the last few years, smartphone shipments only make up 20% of total handset shipments, as of the first half of 2010, reported data showed that global smartphone shipments increased 74% from 2009 to 2010.
4. Turning Point Seeing as though the demands for smartphones are increasing, it is highly evident that smartphones are very efficient in this day and age. So the point is why should they have a negative effect on society, education, productivity, communication in the work place, and social engagement? In society smartphones improve communication skills via instant messaging. Smartphones improve education by allowing students to access information much easily. They also allow communication in the workplace much faster as the staff can communicate via instant messaging. And finally smartphones can improve social engagement by having a faster way of communication allowing social engagement to become more successful.
5. More Statistical information Smartphones make everyday lives easier, faster, efficient and mobilised. When used in the right way there is no reason why smartphones would have a dent in our society. No matter the debate around the topic smartphones will continue to excel on the market and also continue to improve our everyday lives. According to Tylutki, Y. (2009). Research Studies Effects of Smartphone on Information Literacy. Scranton university. Available at. http://‘’There's a lot of consensus that within the next five to ten years, cell phones will be the way that most people access the Internet most of the time.’’ This piece of information defends the vitality of smartphones in this day and age. Meaning is there possibly anyway smartphones can harm society?
6. Research Findings Research from Scranton university shows how smartphones have had a positive effect on their campus as illustrated in the previous slide. The university rates that smartphones are the future and that they are the key to communication. Most importantly the university found out that their library systems flow more efficiently as almost everyone has access to the school network with their cell phones. With this type of research going in favour of opposing the topic statement, how can it be possible that smartphones are having a negative impact on our society?
