چکیده

In this paper, we present the probably first application of the popular Dynamic Movement Primitives (DMP) approach to the domain of soccer-playing humanoid robots. DMPs are known for their ability to imitate previously demonstrated motions as well as to flexibly adapt to unforeseen changes to the desired trajectory with respect to speed and direction. As demonstrated in this paper, this makes them a useful approach for describing kick motions. Furthermore, we present a mathematical motor model that compensates for the NAO robot’s motor control delay as well as a novel minor extension to the DMP formulation. The motor model is used in the calculation of the Zero Moment Point (ZMP), which is needed to keep the robot in balance while kicking. All approaches have been evaluated on real NAO robots.

A Dynamic Kick for the Nao Robot

Our research is concerned with making a dynamic, closed loop, stabilized kick for the Nao robot. The Nao is a humanoid robot made by Aldebaran Robotics. It is used in the Standard Platform League of the RoboCup, an organization which organizes football (soccer) competitions for autonomous robots. Kicking, of course, is an important part of football, and thus a good kick is vital to achieving go...

Adaptive Motion Control: Dynamic Kick for a Humanoid Robot

Automatic, full body motion generation for humanoid robots presents a formidable computational challenge. The kicking motion is one of the most important motions in a soccer game. However, at the current state the most common approaches of implementing this motion are based on key frame technique. Such solutions are inflexible and cost a lot of time to adjust robot’s position. In this paper we ...

Online Generated Kick Motions for the NAO Balanced Using Inverse Dynamics

One of the major tasks of playing soccer is kicking the ball. Executing such complex motions is often solved by interpolating keyframes of the entire motion or by using predefined trajectories of the limbs of the soccer robot. In this paper we present a method to generate the trajectory of the kick foot online and to move the rest of the robot’s body such that it is dynamically balanced. To est...

An Omni-directional Kick Engine for Humanoid Robots with Parameter Optimization

Incorporating a dynamic kick engine that is both fast and effective is pivotal to be competitive in one of the world’s biggest AI and robotics initiative: RoboCup. Using the NAO robot as a testbed, we developed a dynamic kick engine that can generate a kick trajectory with an arbitrary direction without prior input or knowledge of the parameters of the kick. The trajectories are generated using...

Analytical Dynamic Modelling of Heel-off and Toe-off Motions for a 2D Humanoid Robot

The main objective of this article is to optimize the walking pattern of a 2D humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. To this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. Then, using these trajectories and the inverse kinematics, the position tra...
