This article is about the third generation of Actroid, the Actroid DER3. She comes as the younger sister of the DER2. This type Actroid uses the same technology as her successor. The different is that she has improved her expression. She, now, can move her arm as well as her foot in a particular movement. For an example when you hold her hand, then she just can move her foot just like kicking a ball. She can move her hand forward as the position like asking to shake your hand or welcome you. With her appearance now she is looking more formal than her sister, but she has the same pretty face with more expressions.
