The goal of this project is to use shape-memory-alloy actuators to realize a wriggling creature. Normally, a shape-memory-alloy actuator generates a well-defined action (robot appendages grip something or walk). But in this project, precisely controlled actuators express wriggling and creature expression. It demonstrates that an assembly of actuators can be… (More)
When we see the wriggling movement and the shape of a tentacle like the sea anemone under the sea, we feel an existence of a primitive life. The goal of this research is to realize the expression of a kinetic artwork or interactive artwork such as waving tentacles of sea anemones. At present, soft actuators that bend in multiple directions have been… (More)

We propose the concept of shape memory alloy motion display (SMD), a new type of physical display, and introduce a plant-shaped robot "Himawari" based on this technology. SMD is a display apparatus taking advantage of existence of an actual object, and gives visual expressions by movement and change in shape of actuators, which are components of this… (More)
The Luminescent Tentacles system is a scalable kinetic surface system for kinetic art, ambient display, and animatronics. The 256 shape-memory alloy actuators react to hand movement by fluid dynamics and Kinect. These actuators behave like waving tentacles of sea anemones under the sea, and the top of the actuator softly glows like a bioluminescent… (More)
Himawari is a sunflower robot composed of mechanical parts and electronic parts, such as servo motors, LEDs and shape-memory alloy actuators, that reacts, slowly and fluidly, facing and communicating to humans in front of it.
