Heavy Duty Pan and Tilt

thingiverse

UPDATE - 10 September, 2018 - Steplab's folks in Europe just contacted me with an update to their site address Main site - https://steplab.net/ Couplers page - https://servocity.eu/ct/servo-en/servo-couplers/ When building a pan setup for my big Talon to carry a 2-axis brushless gimbal, I was looking for components that could be bought to build a sturdy 360-degree pan mechanism without gears, belts or extra linkage parts. I found the components I needed at Actobotics. This project is an extension of earlier work on my big Talon and some of the Mini Talon. After buying and building several Pan and Tilt setups, I got tired of how cheaply purchased ones were and how flimsy most were. The biggest problem was that the pan axis was never robust enough. When I found something strong enough, it was always too heavy or expensive or presented too much wind area. With Actobotics pieces, their Futaba servo coupler and bearing plate, I built a raised bearing that made the servo connection very strong. This structure keeps all stresses off the servo shaft and its bearings and eliminates unwanted motion or wobble. Here are the STL files and some pictures of what it looks like. I set it up to be configurable with three different mounts for flat decks, three different camera plates to accommodate different cameras and a version that puts two cameras in an over-under configuration that could be used in a head tracking setup. The 360 Servo The base pan servo is the current version of the GWS S125-1T Sail Winch servo. It has good centering characteristics, will actually travel 385 degrees, it's quite smooth and makes monster torque (~7kg). There are two versions of this servo, one with a 23-tooth spline which was discontinued two years ago and the one for this project which has a 25-tooth spline identical to Futaba.
