Taking a cue from nature and maybe Geico, researchers at Simon Fraser University Burnaby have created a gecko-inspired robot , the Timeless Belt Climbing Platform (TBCP-II), in a position to climbing smooth walls or across ceilings with lizard-like foot pads. The feet, constituted of fibrillar adhesive polydimethylsiloxane (PDMS), act as grip due to a small mushroom cap design 17 micrometers wide and 10 micrometers high for optimum surface exposure. The 240g tank-like machine is usually somewhat independent, using sensors to detect its surroundings to modify course according to obstacles in its way, taking us one step toward… the inevitable . Take a look at the video and entire PR after the break.
Scientists reach the heights with gecko-inspired tank robot
Researchers have developed a tank-like robot that has the facility to scale smooth walls, opening up a sequence of applications starting from inspecting pipes, buildings, aircraft and nuclear power plants to deployment in search and rescue operations.
Their study, published today, 1 November, in IOP Publishing’s journal Smart Materials and Structures, is the 1st to use this unique, bioinspired material to a robot that operates in a tank-like manner.
This system offers a substitute for the magnets, suction cups, spines and claws which have all been presented as possible mechanisms, but appear to fall on the same hurdle – the facility to climb smooth surfaces akin to glass or plastic.
Drawing inspiration from the gecko, researchers were capable of create adhesives that carefully mimic the toe pads of the lizard that give it the superb ability to climb smooth vertical surfaces and shuffle across ceilings.

Tank-like robots, driven by belts in place of a group of legs, are advantageous in that they’ve a simplified mechanical design and control architecture, have an increased mobility and will be easily expanded, a twin of a train, in order for you to extend the weight the robot is carrying.
The brand new, 240g robot, often known as the Timeless Belt Climbing Platform (TBCP-II) and developed by researchers at Simon Fraser University Burnaby, is able to reliably transferring from a flat surface to a wall over both inside and out corners at speeds of as much as 3.4cm/s.
TBCP-II is additionally fitted with a mess of sensors which are capable of detect the environment of the robot and alter its plan of action accordingly.
Lead author, researcher Jeff Krahn, said: “With an adequate power supply, our robot is in a position to functioning fairly independently when it encounters larger-scale objects akin to boxes or walls. However, we’re still developing a control approach to make sure the robot is able to fully autonomous functionality.”
The toes of geckos have amazing characteristics that permit them to stick to most surfaces and research means that they work as results of van der Waals forces – very weak, attractive forces that occur between molecules.
These dry, but sticky toe pads, generally known as dry fibrillar adhesives, were recreated within the lab using the fabric polydimethylsiloxane (PDMS) and were manufactured to contain very small mushroom cap shapes that were 17 micrometres wide and 10 micrometres high.
“While van der Waals forces are considered to be relatively weak, the skinny, flexible overhang provided by the mushroom cap ensures that the realm of contact between the robot and the outside is maximized.
“The adhesive pads on geckos follow this same principle through the use of plenty of fibres, each with a really small tip. The more fibres a gecko has in touch, the greater attachment force it has on a surface,” Krahn continued.
