The YELANGU Motorized DSLR Dolly, in black with orange accents, runs on a flat surface and can make straight as well as circular moves in either direction. The dolly is designed to work with DSLR and mirrorless cameras weighing up to 6.6 pounds. It includes a reversible 1/4"-20 to 3/8"-16 threaded stud mount for your camera or ball head, and can support smartphones with a separately available Smartphone clamp. The dolly has three speed selections.

You can control the direction and speed of the dolly directly on the unit or by using the included remote control, which has a range of slightly more than 19'. The dolly incorporates compound wheels for flat surfaces and slider tracks, and the adjustable wheel base allows you to adjust the dolly to ride on slider tracks with varying distances between the rails. You can adjust the angles of two of the wheels to create circular moves, and these angles are indexed for repeatability.
