The spider robot at the moment is simply a platform. I don’t have a purpose for it yet. I saw the designs on Instructibles.com and had to make one. The original platform was called Terra Spider. Its original purpose is to perform sampling of contaminated areas that may be too hazardous for humans to work. The concept is a group of these Terra Spiders would be delivered to an area via drone, or quadcopter. Once there they would work cooperatively to cover the area and sample the environment. I don’t have a use or interest in sampling but the platform intrigued me, so I modified it for my own use.
