Some experimental robots use suction-based grasping systems to climb smooth surfaces, but these technologies do not work on rough surfaces such as rocks.
It is possible to climb rough surfaces with micro thorn holders
As an alternative to this microspine holders A mechanism called These are devices that attach to small recesses and protrusions on the climbing surface. series of small sharp hooks Contains. The hooks are released from the surface when the gripper is lifted to move on to the next step.
Some microspike grippers work passively and rely on the weight of the robot’s suspended body to maintain grip. This species works well on relatively flat walls but struggles on more irregular surfaces such as rocks, which require more varied climbing strategies.
Active microbarb grippers overcome this limitation by using electric actuators that deliberately sink a series of hooks into the surface, providing a motorized grip that works in any direction. However, they are bulky, mechanically complex, have high energy consumption, and offer a very slow rate of climb.
Named after a climbing marsupial and also from the words “Lightweight Observation Robot for Irregular Slopes” LORISdeveloped by researchers at Carnegie Mellon University’s Robomechanics Laboratory.
Inspired by insects
Using the built-in depth-sensing camera and microprocessor, the robot continues its movement so that when the gripper on one leg catches the climbing surface, the gripper on the opposite leg also grabs the climbing surface. As long as these two crossed legs maintain inward tension on their grippers, the grippers remain firmly attached to the surface. Meanwhile, the robot’s other two opposing legs are free to take the next step upward. This, directed inward grip known as, insect inspired an escalation strategy.
According to researchers, LORIS combines the lightness, speed, energy efficiency and simplicity of passive microbarb grippers with the firm grip and adaptability of active grippers. In addition, it is stated that the robot is designed to be easy and cheap to produce.
