Robot Gimbal for High-Resolution Panoramas
Description
Portable, tripod-mounted, lightweight gimbal robot for high-resolution spherical panoramas. Rotates a camera 360° horizontally and 180° vertically to cover the entire surroundings, minus the small footprint of its circular tripod mount. Can be used for spherical panoramas, gigapixel photography, timelapse photography or even DIY pan-head for any small camera. Its design goals are low weight and size so it can be used while traveling, so some compromises were made in that direction. The camera movement is slow, this is not a real-time stabilization gimbal. Best suited for photos intended to be stitched into very large panoramic images. The camera can be mounted to rotate around its "nodal point" (optical center), both vertically and horizontally, to avoid parallax errors that cause stitching problems with regular gimbals. Vertical positioning is achieved by a rail slide built into the unit, and horizontally by the offset camera mount. This is part of a larger project that includes an Arduino controller and smartphone (iOS) control app. https://www.facebook.com/panocontroller/videos/526181134821047/ Parts needed - (2) 28BYJ-48 motors - (4) 688-2RS bearings (8x16x5mm) - https://smile.amazon.com/gp/product/B00ZVF8EMU - (1) 1/4" tripod screw with D or flat head (see pictures) for attaching camera - (1) 5/8" to 1/4" tripod adapter for the tripod mount - both in https://smile.amazon.com/Muscccm-Camera-Tripod-Adapter-Converter/dp/B07BKPXR72 - some grip tape or TPE layer to avoid slippage for tripod and camera mounts Some parameters can be tweaked in Autodesk Fusion 360. The complete Fusion 360 model (provided as-is) is at https://a360.co/2ztelQZ (Autodesk short link). There is a load test simulation model there as well, it's inaccurate due to materials but insightful nevertheless.
