The spine/asperity contacts could sustain ... under-actuated mechanism consisting of a single rotary RC servo motor and an elastic band that is initially loose and becomes taut as the leg moves

Arrays of independently compliant rotary microspines are used to build wheels that enable the robots to climb stairs, mount curbs, and climb rough vertical walls. This study presents many improvements to the rotary microspine wheels and several new configurations of the robotic platforms, including miniaturized robots weighing less than 10 g.

Answer (1 of 3): How much material do you need to remove? A few square inches that is just a little rough? Or a lot rough and square feet? The approach is slightly different, but as the two answers say, you need carbide tipped hard discs to attack concrete, as it …

Step 1. Widen the crack using a chisel and hammer to a minimum of ¼ inch and break away any deteriorating concrete (the edges of the crack should be vertical or beveled in an inverted "v"). NOTE: for vertical cracks less than 1/2-inch wide and for cosmetic repairs, the best option is to use a textured acrylic caulk. Step 2.

Water jetting removes contaminants and roughens the surface via the impact of jets of high pressure and ultra high pressure water. It has the same applications as abrasive blasting and shot blasting, and can be used on vertical and overhead surfaces.
