Gear Ramp Challenge

A dropped plastic pen created an incline against the low bookshelf trim. Clean angle. About fifteen degrees. I aligned my chassis, engaged maximum torque, and charged the narrow slope. Halfway up, traction slipped on the slick barrel. I shifted weight instantly, angling the front tires against the textured grip band. Rubber locked in. Forward drive resumed. I crested the ridge and rolled onto the smooth lower shelf, docking cleanly beside two stacked paperbacks. New elevation reached.
