In the last three decades, the field of robotics knows great flourish and acceptance, both at research level and application in everyday life. Nowadays, the rapid evolution appears from the applications and the deployment of almost all over the world and from the research results. Countries such as Japan, US and Western and Eastern European countries, which have made significant progress to...
Pentapod Robot first steps using IK, Gait and Blending IK
Here it is… the first steps of our pentapod. Even if the algorithm produces precise results, the servo angle do require some offsets to work smoothly … and of course better servo motors (not these cheap and unbalanced). The motion system is using a GAIT sequencer to produce the motion frames and the IK algorithm translates them into actual servo angles. Moreover a blending algorithm...
Sensory system in autonomous robots
A tele-supervised autonomous robot needs to have accurate information on its position, orientation, and velocity and the location of nearby obstacles (sensory system). The robot needs multiple sensors to gather all the information required and a computer to read the sensor data and make decisions based on it. Information on the robot’s environment can be acquired using laser distance sensors...
Inverse Kinematics Algorithm for Pentapod (five-legged) robot
Inverse kinematics is a much more challenging problem than forward kinematics. It is the procedure when we have a desired end effector position but need to know the joint angles required to achieve it. The solution of the inverse kinematics is computationally expensive, and usually, it takes long time for the real time control of manipulators. Singularities and nonlinearities that make the...
Pentapod Robot Stretching using IK Algorithm
After almost 2 months of hard work… the results of the five legged (pentapod) robotic platform are acceptable. For the development of this all-terrain robotic platform, i am using two ARM Cortex M4 microcontrollers using a Real-time Operating System (RTOS) as well as a simple sensory system. The communication between the microcontrollers was established using the Controller Area Network...
Inverse Kinematics using Fuzzy Logic
What Is Inverse Kinematics? Kinematics is the science of motion. In a two-joint robotic arm, given the angles of the joints, the kinematics equations give the location of the tip of the arm. Inverse kinematics refers to the reverse process. Given a desired location for the tip of the robotic arm, what should the angles of the joints be so as to locate the tip of the arm at the desired location...
A few words about Locomotion
A mobile robot needs locomotion mechanisms that enable is to move unbounded through-out its environment. However, there is a large variety of possible movement ways and so the selection of a robot’s approach to locomotion is an important aspect of mobile robot design. Most of the locomotion mechanisms have been inspired by their biological counterparts. Biological systems succeed in moving...
Autonomous Robots and Application Types
Robots are mechanical or virtual artificial agents, usually electro-mechanical machines which are controlled by a computer program or electronic circuitry. There are separated into different categories depending on their functionality. Most popular robots are placed in hazardous places because these robots perform the tasks that humans are not able to access. Some robots(autonomous robots) can...
