Akahoshi uses his jutsu to try to kill him.

They all find the bandit, who is actually Sumaru's mother, Natsuhi. Shortly after, Sumaru is guiding Neji, Tenten, and Lee, with the other Hoshigakure genin, to find the mysterious bandit that stole the star. Sumaru is rescued by Tenten and Rock Lee. Sumaru is taken away by Akahoshi posing as the real mysterious bandit as the other ninja collapse from the side effects of the Star Training.Īkahoshi puts him in "suspended animation," and as Sumaru lays unconscious, he dreams about when the Third Hoshikage tells Sumaru about his parents dying to protect the star, and tells him to be strong and to make his parents proud. When the star is stolen by a mysterious bandit, Akahoshi charges Sumaru and his friends to get it back. Naruto misinterprets Sumaru's actions as an attack, and has a brief, uneventful battle, during which, the Konoha genin witnessed first-hand the Mysterious Peacock Method in battle. He first encounters Naruto at the edge of the Land of Bears where he stops the Konoha genin from walking into a canyon filled with toxic gas, the "Devil's Ravine". When first shown, Sumaru showed some skill with a crossbow, using it in conjunction with a rope to cross the "Devil's Ravine", while showing great sense of balance when running over aforementioned length of rope. When Akahoshi kidnapped Sumaru, Yotaka said that he was one of the village's most talented genin, indicating that Sumaru had much more control over the Star Chakra, in a similar way to that of his mother's. While cooperating with other genin he was shown to be able to sense the star's presence. He also proved capable of using a technique called Chakra Rope, albeit in a smaller version when compared to his mother's. Sumaru was able to use the Mysterious Peacock Method, seen when he was able to create wings made out of chakra to fly and when he could use said wings for an offensive attack. Sumaru has reddish-brown eyes and long smooth black hair that he wears in a braided ponytail, his bangs partly curl around his head and parts of his blue Hoshigakure forehead protector.Īs a child Sumaru's hair was short and straight and not as smooth. Sumaru remembers his mother, especially, through a lullaby she sang to him as a child about a red star called Natsuhiboshi, which is actually the planet Mars. As a last favour, they asked the Third Hoshikage to lie to Sumaru to protect their family name. Sumaru is told that his parents, Natsuhi and Hotarubi, were killed in battle guarding the fallen star, when in reality, they stole it in an effort to save the villagers from the damaging effects of star training. He appears to be one of their more prodigious practitioners, being able to perform some of the more advanced techniques of star training at such an early age. The validated results can provide guidelines for the design of functional, self-bending actuators using 3D printing.Like the other ninja of Hoshigakure, Sumaru takes part in star training, a technique which allow incredible chakra control, at the expense of severe physical health damage. The proposed model predicts the final shape of the actuator with excellent qualitative agreement with experimental studies. Also, experimental tests carried out to validate the proposed parametric model. A parametric study of physical properties of polymer pane incorporating 3D printed patterns is conducted. The hinges function as a heat source to absorb a wide range of light, particularly the infrared light, convert light energy to thermal energy and cause the underlying printed area to heat up faster than the unprinted area leading to actuation due to thermal stress gradients.

A polystyrene (PS) pane as a representative of thermo-responsive shape memory polymers is used as the main material for being remotely stimulated via light emission while the actuation hinges are made of printed chitosan hydrogel ink.

It is shown that 3D printing control parameters such as different spatial patterns of hinges affect the response time and bending angle of the actuator. This paper studies the features merely imparted by 3D printing fabrication in control of self-folding actuators. Three-dimensional (3D) printing is a promising rapid and accurate manufacturing method for controlling spatial self-bending actuation in custom-designed soft structures. Self-bending actuators have time and cost reduction benefits for applications like self-assembly and self-deployable structures.
