Arachno means spiders. Arachnobot is a spider robot whose legs are 20 centimeters long. Arachno-Bot is a printable spider robot built as an exploratory tool in environments that are too hazardous for humans. It gets its name because of its movement and look as a real spider. Fraunhofer Institute for Manufacturing Engineering and Automation in Stuttgart, Germany has developed Arachno by using a natural spider as the model for their robot, which they created through 3D printing.
