Embodied robots have the potential to better understand and communicate with humans in natural language due to their ability to sense their environment through multiple modalities such as vision, audio, haptics and proprioception. They can also move and influence the world through their actions, enabling more active exploration of the environment. Our research explores how multimodal perceptual information can be used to better understand language, and motor skills can be used to actively engage with humans to learn natural language through interaction, particularly through dialog and games such as "I Spy."
