Teaching Recursion in High Schoollum. In this paper, we outline an approach that has its focus on introducing the concept in very small steps, integrating recursion into a K-12 programming class. The main paradigm is to be as constructive as possible in that everything that is introduced is also implemented right away from the first lesson on.

s dynamics are thus used to aid in the reconstruction of a time varying field. The algorithms used were tested, mainly on student-built marine robots that collaboratively surveyed a coastal lagoon in Grand Isle, Louisiana that was polluted by crude oil during the Deepwater Horizon oil spill.

Our evaluation shows that: in-buffer processing of ROS messages without relying on dynamic memory allocation is possible; message contents can be accessed conveniently using well-known concepts of the C language (structs) with negligible processing ov

Nata?a Grgurina,Sabiha Yeniranging measure very noisy, thus limiting the accuracy of simple localization techniques. We first present a SLAM technique based on an Extended Kalman Filter (EKF-SLAM) to integrate RSS measurements from the different nodes over time, while the robot moves in the environment. Successively, we show

Tomas ?iaulys,Valentina Dagien?These mobile anchors are aware of their own locations and move in order to cover the entire network, and then try to infer locations of sensor nodes using various techniques e.g. geometric, statistical etc. Thus, keeping this in mind the chapter presents key issues and inherent challenges faced by t

Karin Tengler,Oliver Kastner-Hauler,Barbara Sabitzer the design of a robotic platform in which a desired level of localization accuracy is to be achieved. We also analyze the distortions in the time difference of arrival and frequency difference of arrival measurements caused by different clock offsets and skews at the robots. We propose a robust alg
