Detecting Falling Rocks by Estimating Excavation Points Using Laser Pointer

Abstract. The current study investigated individual differences in the flexibility of peripersonal space (i.e., representational space near the body), specifically in relation to trait claustrophobic fear (i.e., fear of suffocating or being physically restricted). Participants completed a line bisection task with either a laser pointer (Laser condition), allowing for a baseline measure of the size of one’s peripersonal space, or a stick (Stick condition), which produces expansion of one’s peripersonal space. Our results revealed that individuals high in claustrophobic fear had larger peripersonal spaces than those lower in claustrophobic fear, replicating previous research. We also found that, whereas individuals low in claustrophobic fear demonstrated the expected expansion of peripersonal space in the Stick condition, individuals high in claustrophobic fear showed less expansion, suggesting decreased flexibility. We discuss these findings in relation to the defensive function of peripersonal space and reduced attentional flexibility associated with trait anxieties.

Teknologi elektronika berkembang pesat. Salahsatunya pada bidang robotika. Robot pelontar, merupakansebuah pengembangan teknologi sederhana hingga teknologiyang kompleks. Pengembangan robot yang paling sederhanaadalah pengembangan dalam bidang pendidikan, salah satunyatermasuk penggunaan robot pelontar untuk mengatasimasalahan dalam lomba KRI 2017. Dalam lomba ini, robotpelontar mampu menembakkan peluru yang disebut dengansoftsaucer kearah tiang yang memiliki penampang, danterdapat objek tembak di atas penampangnya. Tujuan daripelamparan softsaucer kearah bidang tembak adalah untukmenjatuhkan objek tembak dari atas bidang tembak.Penembakan softsaucer oleh robot pelontar kearah bidangtembak memiliki jarak yang sudah ditentukan. Letak bidangtembak yang memiliki jarak yang berbeda – beda dari robotmembuat robot harus bisa menyesuaikan sudut elevasitembakan agar objek tembak berhasil dijatuhkan. SensorSRF08 digunakan untuk mengukur jarak dari robot ke bidangtembak dengan bantuan laser pointer, agar jarak yang diukurmerupakan jarak dari robot ke bidang tembak. Agar pelontaransoftsaucer bisa mengenai sasaran, digunakan metode PID,dimana mencari nilai konstantanya dengan cara Trial andError. Setelah dilakukan tuning, dengan nilai konstanta Kp=40, Ki= 5, Kd= 37, robot dapat menyesuaikan sudut elevasitembakan dengan respon waktu yang cepat yaitu 5 detik.
