Attractnid is a four legged robot which can scale metal surfaces. It relies on magnets to attach itself to surfaces and looks like a spider (despite only having four legs).
The robot uses feet with permanent magnetics to attach to surfaces. Servos on the top of the feet rotate a permanent magnet to cancel the magnetic fields to detach the leg, allowing another set of servos to rotate the legs.
An accelerometer keeps track of the orientation of the robot, allowing the robot to move along any specified angle.
Our mechanical system consists of magnetic switches and sliding legs controlled by servos.More
Our electrical system consists of an Arduino Mega, an accelerometer, and a bluetooth chip, and is powered by a battery.More
Our software system is written in C++, and uses a control robot to walk the robot along a desired heading.More
