WinchBot is a robotic arm composed of 3 winches and 5 servos

Using an Arduino Uno along with a Raspberry Pi for control, hacker “HomoFaciens” came up with this clever delta-style robot.

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.
