2019.05.31(am): How to draw a spiral out of squares with python turtle
Today I used a Python Turtle to draw a square spiral. Below is a picture of the drawing. Yesterday I used Python for the base, because I forgot to develop Python in a virtual environment. So today I did not forget to activate the virtual environment. code
2019.05.30(am): What is turtle? How to make python turtle works in jupyter notebook
Turtle Graphics Turtle graphics is a popular way for introducing programming to kids. It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966. The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses tkinter for the underlying graphics, it needs a version of Python installed with Tk …
2019.05.21(am): Development of an Amphibian Legged Robot Based on Jansen Mechanism for Exploration Tasks
link: https://doi.org/10.1007/978-981-10-2845-8_7 authors:Gopi Krishnan RegulanGanesan KaliappanM. Santhakumar abstract:The paper discusses the development of a linkage based amphibian legged robot for exploration and surveillance tasks. The proposed system can walk on both ground and water surfaces. The proposed system has two major mechanisms for its motion namely a planar eight bar Jansen mechanism as a leg and an Ackermann steering …
2019.05.19(am): Study of Applications of Jansen’s Mechanism in Robot
authors: Somak Sengupta, Pramod Bhatia abstract: The natural and the manmade terrains on planet Earth vary from place to place. The availability of affordable and safe modes of transportation on the different types of terrain is currently costly and limited. This problem is mainly due to the limitations of wheels which fail to deliver on …

link: https://doi.org/10.1016/j.robot.2008.11.003 authors:Jose ManuelPeula, Cristina Urdiales, Ignacio Herrero, Isabel Sánchez-Tato, Francisco Sandoval abstract:A traditional problem in robotics is adaptation of developed algorithms to different platforms and sensors, as each of them has its specifics and associated errors. Hierarchical control architectures deal with the problem through division of the system into layers, where deliberative processing is …
2019.05.18(am): Design, control, and energetics of an electrically actuated legged robot
link: 10.1109/3477.604106 authors:P. Gregorio ; M. Ahmadi ; M. Buehler abstract:To study the design, control and energetics of autonomous dynamically stable legged machines we have built a planar one-legged robot, the ARL Monopod. Its top running speed of 4.3 km/h (1.2 m/s) makes it the fastest electrically actuated legged robot to date. We adapted Raibert’s control laws for the …

link : 10.1109/ICRA.2013.6631038 authors : Sangok Seok ; Albert Wang ; Meng Yee Chuah ; David Otten ; Jeffrey Lang ; Sangbae Kim abstract:In this paper, we introduce the design principles for highly efficient legged robots and the implementation of the principles on the MIT Cheetah robot. Three major energy loss modes during locomotion are heat losses through the actuators, losses through the transmission, and …

link: https://doi.org/10.1177/0278364903022003004 authors: Yasuhiro Fukuoka, Hiroshi Kimura, Avis H. Cohen abstract:We have been trying to induce a quadruped robot to walk with medium walking speed on irregular terrain based on biological concepts. We propose the necessary conditions for stable dynamic walking on irregular terrain in general, and we design the mechanical system and the neural system by …
