In the past few years, we have covered a whole host of smart sliders that can drastically increase your production value. The Moza Slypod E Motorized Monopod is also worth a look. It can be mounted horizontally or vertically to allow motorized dolly/track/book shots.
The Slypod E has horizontal and vertical payload capacity of 9lb/20lb respectively. It has buttons on it to allow 10 different speeds. The companion iOS/Android app lets you set up travel routes, change speed, and do a whole lot more. The battery lasts for up to 2 hours.
