Pathfinder Mini - Spiderbot

The Pilot Hobbies Pathfinder Mini is an easy to control 6-legged walker, which only requires two motors to allow walking in all 360 degrees, plus a servo for head tilt. The Pathfinder Mini has been designed to be a great introductory educational or learning platform, allowing the creator to focus more on problem solving, sensors, and functional programming of the robot, without the headache of managing multiple servos per leg or complex inverse kinematics equations.

Due to its simple nature, this robot lends itself well to not only microprocessor-based circuits, but also analog circuits and discrete logic gates. My personal build uses a BEAM Robotics style analog circuit, with 555 timers and transistor logic, for all its functions.

A single N20 Gear-Motor drives the walking mechanism, while a second N20 Gear-Motor rotates the head and drive assembly. This allows extremely easy control, without complicated walking code or servo control. Head panning and tilting is also simple to a
