Meet the DollyPLUS from edelkrone: a motorized dolly that combines with your camera and tripod for curved and smooth straight slides. It can move any tripod on flat surfaces. You can combine it with a motorized head to program 4- and 5-axis camera motions.
Your edelkrone devices can be controlled from one app. They work with iOS and Android devices. The DollyPLUS has max 30lb carrying capacity while the Pro version can handle 45lb of load. Thanks to this motorized dolly, you can select multiple points on a straight line and have your camera slide to those points or loop between them.
