Teach Robots must be able to successfully negotiate barriers in order to participate in search and rescue activities. Vegetation is one region that is both common and challenging to enter.
Robots often employ a variety of sensors, including ultrasonic sensors, Lidar (Light Detection and Ranging), infrared sensors, and camera systems, to sense their environment. These don’t happen frequently enough, though, for robots to truly navigate around the foliage that characterizes outdoor settings in real life.
Because of this, engineers from Carnegie Mellon University are attempting to find a solution to this specific problem.
Bringing A Robot Outside
“When you take robots outdoors, the entire problem of interacting with the environment becomes exponentially more difficult because you have to be more deliberate in everything that you do,” said David Ologan, a master’s student at Carnegie Mellon studying mechanical engineering.
Your system must be strong enough to deal with any obstacles or unanticipated scenarios that may arise. Approaching a topic that isn’t necessarily solved yet is exciting.
Engineers are developing a reactive walking method to be used on a quadrupedal robot to create this kind of system. The Carnegie team selected these robots because they are far more suited than their wheeled counterparts to avoid vines and branches.
The developers then went on to develop a particular kind of robot that is capable of keeping an eye on its own limbs to determine if anything becomes trapped on them and then taking the necessary measures to free them. Not an easy feat, this!
In contrast to driving over everything, “legged robots can select footholds and step over things,” Ologan remarked. “The issue with this is that you have to consider your footholds with every step. The mechanism is quite sensitive. We need ways to react to external touch because if your robot runs into a step, it may topple over completely.
Retracting Its Legs In Response
The engineering team experimented with a variety of methods, including high-stepping and a knees-forward stance, to free the robot’s legs from impediments. None of these, however, were as effective as letting the robot withdraw its legs in response.

The new approach can be incorporated in the operating systems of other robots without having to make any changes to their hardware, which means that the system is highly configurable and adaptable. Applications for the new method are many and varied. Effective obstacle avoidance and navigation are crucial for a wi-fi enabled robot.
