Alex Kruskal

About

Alex Kruskal is a pioneer in human-robot interaction and child-computer interaction, best known for foundational work on robotic pets that empower children’s storytelling. Their landmark paper “Designing PETS” (1999, 102 citations) introduced a modular robotic pet system—PETS—that children could physically assemble and then program through the My Pets software to act out their own narratives. This work was among the first to blend tangible user interfaces with social robotics, demonstrating how interactive technology could support creative expression, narrative development, and emotional engagement in young users. By enabling children to both build and animate their robotic companions, Kruskal’s research laid critical groundwork for later developments in educational robotics, computational thinking, and child-centered design. The PETS project remains a touchstone in the field, cited for its innovative integration of constructionist learning, storytelling, and robotics. Kruskal’s contributions have influenced subsequent generations of researchers exploring how robots can serve as co-creative partners in learning environments. Their work continues to inspire new approaches to designing interactive systems that foster imagination, agency, and collaboration in children.
