Update: Rover Drive Train Update #3
Update: Drive Train Update #2
I use the term DIY loosely on this, as the only thing that is custom is the rover itself. The eMotimo TB3 is a time lapse robot that is normally used by itself, or in conjunction with a slider. I do have a 6 foot T-slot slider that I'll by using with the TB3 and Dynamic Perception stage zero hardware with quick release. The problem is that the slider limits the distance you can make the camera travel. After my recent DIY Actobotics projects, including the Slow Motion Cable Cam, Mini Auto-Reverse slow motion slider, and adjustable width slow motion ladder dolly, I came up with the idea that a hyperlapse rover would be a complimentary addition to my Time Lapse fleet. I call it a "hyperlapse" rover only because it has the ability to cover much larger distances, time and patience permitting.
I used Actobotics parts from Servocity.com to build this simple rover that uses a stepper motor and RC Monster Truck wheels to push itself forward. The eMotimo TB3 allows for 3-axis moves in 2 or 3 step sequences, where you select a start point and then drive the rover to the end point. Once you set the interval and how long you want the sequence to take, the TB3 takes over and drives back to the start point to begin the sequence. Unlike my ladder dolly, which moves very slow, but never stops, the eMotimo Rover takes a picture, then moves forward and stops, then repeats until you get to your end point. Very simple set up.
