Forward Kinematics in Robotics Using Screw Theory

Forward Kinematics, Fundamentals of Robotics 👉🏻

Can you recall a time when you were frustrated when attempting to compute the forward kinematics for robotic systems? Did you find it frustrating to assign coordinate frames to each link when robots become more sophisticated? The frustration caused by assigning coordinate frames for each link while solving the forward kinematics of robotic systems using methods like Denavit-Hartenberg is REAL. If your answer to these questions is yes, and you're tired of cumbersome methods like Denavit-Hartenberg to calculate the forward kinematics of robotic chains, this lesson is for you. The Denavit-Hartenberg is one of the methods to derive the forward…

What is Mechatronics Engineering?

Fundamentals of Mechatronics

Mechatronics systems are present everywhere today, from aircraft flight control and navigation systems to drones to car airbag safety systems to robots to smart home appliances and even some toys. Aircraft Flight Control and Navigation System a Drone The car airbag safety system is a Mechatronics system. Industrial robot arms are Mechatronics systems. Smart Home Appliances: a Robotic Vacuum Cleaner a Robotic Toy Arm These systems are all familiar to us. But, what exactly is Mechatronics? Mechanical engineering, electrical engineering, civil engineering, and chemical engineering were the primary engineering disciplines of the 20th century. Primary engineering disciplines of the 20th…

Petoi Pet Robot Dog and Pet Robot Cat Educational Robots

Quadrupeds/Hexapods, Robot Categories 👉🏻

Petoi, a company that specializes in developing tomorrow's pet robots, has developed two quadruped robots, a pet robot dog named Bittle and a pet robot cat named Nybble, for stem robotics and educational applications. Pet Robot Dog Bittle, and Pet Robot Cat Nybble. Image credit: Petoi Bittle is an open-source bionic robot pet dog used for learning and play, able to climb up to the ceiling and walk upside down because of its light body. Adding a customized Arduino board can help the robot pet coordinate difficult movements, and adding different sensors will make it capable of perception. It is…

ANYmal Quadruped Robot Climbing Stairs

Quadrupeds/Hexapods, Robot Categories 👉🏻

Researchers at the Robotics Systems Lab at ETH Zürich, who are working on legged robots, tested perception-based motion planning for the ANYmal quadruped robot to navigate terrain and stairs. This video was recorded a few years ago, but it's intriguing to see how what we consider normal now was 20x speed then. ANYmal quadruped robot climbing stairs.

Collaborative Mobile Robots

Cobots, Robot Categories 👉🏻

Northwestern University's Center for Robotics and Biosystems has developed collaborative robots for human-robot collaboration. Mobile Cobots. Image credit: Northwestern University's Center for Robotics and Biosystems In the experiment, three Omnid mobile collaborative robots (mobile cobots) are carrying a large pipe, and they float the pipe so that it has six degrees of freedom (three for positions: x, y, and z movements, and three for orientations: roll, pitch, and yaw rotations) and can easily be controlled by a human operator. Delta robots are three dofs series-elastic manipulators and mobile bases feature three-dof mecanum omnidirectional wheels. Image credit: Northwestern University's Center for Robotics…

an Efficient Leg Design for Energy-efficient Locomotion for Hexapods

Quadrupeds/Hexapods, Robot Categories 👉🏻

Manoonpong and colleagues at SDU Biorobotics have proposed an efficient leg design for energy-efficient locomotion for hexapods. The foot design uses the Fin Ray structure using the effect of different crossbeam angles inside its frame. Image credit: SDU Biorobotics Key features: the locomotion is way better than the #hexapods with hemispherical rubber feetthe robot walks with a wave gaitthe robot can successfully walk on different challenging terrains3D printing with soft material, finite element modeling, and neural control are used to produce an integrative solution This research has potential applications in Biorobotics to study and develop bio-inspired robots resembling the locomotion…
