Motion and manipulation
- AIBO, the robot pet for the home, grew out of Sony's Computer Science Laboratory (CSL).
- Cog, a robot developed by MIT to study theories of cognitive science and artificial intelligence, now discontinued.
- Melomics, a bioinspired technology for music composition and synthesization of music, where computers develop their own style, rather than mimic musicians.
Natural language processing
- AIML, an XML dialect for creating natural language software agents.
- Apache Lucene, a high-performance, full-featured text search engine library written entirely in Java.
