– RatSLAM is a biologically-inspired visual SLAM and navigation system that has been shown to be effective indoors and outdoors on real robots. The spatial representations at the core of RatSLAM, the pose cells, form in a distributed fashion as the robot learns the environment. The activity in the pose cells, while being coherent, does not possess strong(More)
— The Lingodroids are a pair of mobile robots that evolve a language for places and relationships between places (based on distance and direction). Each robot in these studies has its own understanding of the layout of the world, based on its unique experiences and exploration of the environment. Despite having different internal representations of the(More)
Languages change over time, as new words are invented, old words are lost through disuse, and the meanings of existing words are altered. The processes behind language change include the culture of language acquisition and the mechanisms used for language learning. We examine the effects of language acquisition and learning, in particular the length of the(More)
— In this paper we focus on the challenging problem of place categorization and semantic mapping on a robot without environment-specific training. Motivated by their ongoing success in various visual recognition tasks, we build our system upon a state-of-the-art convolutional network. We overcome its closed-set limitations by complementing the network with(More)
