The robot has the ability to climb stairs and go over most terrain. We have spent a lot of time developing this robot so you can use it from the beginning with no issues. The All-Terrain rubber pattern treads are about 3" wide and are reinforced with a nylon mesh with a black rubber tread. The chassis is 3 inches high x 8.25 inches wide x ~19 inch wheel center distance length. The total width of the robot is about 17 inches wide with the flipper arms. The center cavity is large enough for for the motors, batteries, electronics, cameras, etc. The top is flanged with laser cut holes that are tapped for mounting an acrylic cover. The robot is currently geared with a 1: 2 reduction (gear motor to drive wheels). Custom gearing can be requested.
