Biomorphic Robotics

11-Aug-07

Biomorphic robotics is a sub-discipline of robotics focused upon emulating the mechanics, sensor systems, computing structures and methodologies used by animals. In short, it is building robots inspired by the principles of biological systems.

Biomorphic robotics

One of the most prominent researchers in the field of biomorphic robotics has been Mark W. Tilden, who has taken Rodney Brooks’ theory of removing the world model from robots to a low hardware level not even using microprocessors. This is not to say the lack of microprocessors makes something biomorphic – quite the contrary. There is a huge amount of work be done implementing biological nervous and neural networks into computing devices.

Robot Kinematics

11-Aug-07

Robot kinematics is the study of the motion (kinematics) of robots. In a kinematic analysis the position, velocity and acceleration of all the links are calculated without considering the forces that cause this motion. The relationship between motion, and the associated forces and torques is studied in robot dynamics. One of the most active areas within robot kinematics is the screw theory.

Robot Kinematics Model

Robot kinematics deals with aspects of redundancy, collision avoidance and singularity avoidance. While dealing with the kinematics used in the robots we deal each parts of the robot by assigning a frame of reference to it and hence a robot with many parts may have many individual frames assigned to each movable parts. For simplicity we deal with the single manipulator arm of the robot. Each frames are named systematically with numbers, for example the immovable base part of the manipulator is numbered 0, and the first link joined to the base is numbered 1, and the next link 2 and similarly till n for the last nth link.
