Robotnacka is an autonomous drawing mobile robot, designed for eaching beginners in the Logo programming language. It can also be used as an experimental platform, in our case in a remotely accessible robotic laboratory with the possibility to control the robots via the Internet. In addition to a basic version of the robot a version equipped with a gripper is available too, one with a wireless camera, and one with additional ultrasonic distance sensors. The laboratory is available on-line permanently and provides a simple way to incorporate robotics in teaching mathematics, programming and other subjects. The laboratory has been in use several years. We provide description of its functionality and summarize our experience
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
