An Arduino powered robotic arm has been created which offers a unique design when compared to traditional robot arms, and is fitted with a triangular system incorporating three servos.
Watch the video below to see a demonstration of this triangular robotic arm design which uses five standard servos together with an Arduino Uno, Raspberry Pi and Raspberry Pi touchscreen for a controller and has been built by hacker “HomoFaciens”.
If you were going to make a robot with five servos, many Makers would make a robot arm with them and call it a day. HomoFaciens, however, who is known for making amazing machines with minimal tools and improvised materials, instead made something that seems to be a cross between a delta robot and a Skycam.
His device, called “WinchBot,” uses three winches attached to an equilateral triangle frame to move a slider on a central pivoting square rod. This allows the robot’s 5-axis “hand” to be positioned within the robot’s work area. The servos are then tasked with keeping everything in the correct orientation, as well as opening and closing the gripper as needed.
