Using adhesives that mimic the dry, but sticky toe pads of the gecko, by using a material called polydimethylsiloxane (PDMS) that was manufactured to contain very small mushroom cap shapes. The thin, flexible overhang provided by the mushroom cap ensures that the area of contact between the robot and the surface is maximized. Here the adhesive is applied to tank-like robots driven by belts. Tank-like robots have a simplified mechanical design and control architecture and also boast increased mobility and can be easily expanded if there is the need to increase the load a robot is carrying. The 240 g (8.46 oz) robot developed by the SFU researchers, which has been given the catchy name of the Timeless Belt Climbing Platform (TBCP-II) has been fitted with a multitude of sensors that allow it to detect its surroundings and change its course accordingly. It is also able to transfer from a flat horizontal surface to a flat vertical surface over both inside and outside corners at speeds of up to 3.4 cm/s (1.34 in/s).
