A previous study of a sand-swimming lizard, the sandfish, revealed that it swims within granular media at speeds up to 0.4 body-lengths/cycle using body undulations (approximately a single period sinusoidal traveling wave) without limb use. Inspired by the organism, we develop a numerical model of a robot swimming in a simulated granular medium to guide the design of a physical device. Both in ...

A visualized dynamic simulation platform of picking robot based on OpenGL and Matlab is established in order to verify the validity of kinematics analysis and visually reflect the motion process. The robot kinematic model is established with D-H method and the forward kinematic solution for the robot is obtained. The inverse kinematic solution is solved by using the simplified inverse transform...

We study the detailed locomotor mechanics of a small, lightweight robot (DynaRoACH, 10 cm, 25 g) which can move on a granular substrate of closely packed 3 mm diameter glass particles at speeds up to 50 cm/s (5 body length/s), approaching the performance of small, highperforming, desert-dwelling lizards. To reveal how the robot achieves this high performance, we use high speed imaging to captur...

Overview The goal of this project was to have a simulation simultaneously learn a robot's gait as well as body dimensions and compliances—in essence, create a design through machine learning. Can we generate an optimal gait and body design instead of spending much time hand-tuning these parameters? As a practical motivation, the robot used in the simulation was loosely modeled after an actual r...

We describe the problem of motion planning for multiple goals in unstructured environments by using temporal logic for specification of the goals. We solve the problem of mission planning for mobile robots, wherein the goal of the robot can be a complex mission specification rather than a classical "Go from A to B" problem. To achieve this problem we take a two dimensional map of the real envir...

In the chapter the framework for RISE (Risky Intervention and Environmental Surveillance) mobile robot operator training design is presented. The basic idea of the framework is to provide advanced software tools to improve the performance of the mobile robot simulation design that are applicable for operator training. The simulator is the end product of the framework. To achieve realistic rigid...

Spherical mobile robot (SMR) has been studied analytically and experimentally in this paper, a novel design with an internal propulsion mechanism and mathematical models of the robot’s dynamics and kinematics are introduced. A 3D model of robot is built by SOLIDWORKS and then exported to ADAMS2007 for simulation. The results of simulation by combining MATLAB / SIMULINK with ADAMS are presented....

Robot soccer is a standard problem used in Artiicial Intelligence for research on cooperating autonomous robots. This paper shows that simulation of robot soccer also is an excellent application for studying interactive and collaborative visualization. We have implemented a prototype robot soccer application that simulates a soccer match in real time and allows humans to interact with it in var...

In this work, a new approach is proposed to control the manipulators for Humanoid robot. The kinematics of the manipulators in terms of joint positions, velocity, acceleration and torque of each joint is computed using the Denavit Hardenberg (D-H) notations. These variables are used to design the manipulator control system, which has been proposed in this work. In view of supporting the develop...
