The NIST SPIDER, A Robot Crane
The Robot Systems Division of the National Institute of Standards and Technology has been experimenting for several years with new concepts for robot cranes. These concepts utilize the basic idea of the Stewart Platform parallel link manipulator. The unique feature of the NIST approach is to use cables as the parallel links and to use winches as the actuators. So long as the cables are all in t...
متن کاملDevelopment of the Nist Robot Crane Teleoperation Controller
An inexpensive and easy to operate controller has been developed for the teleoperation control of the NIST Robot Crane. This robot crane has the Stewart platform parallel link manipulator design, with cables as parallel links and winches as actuators. The controller is currently capable of rate-position control and force control of the crane platform. The control action can take place with resp...
متن کاملEmergent properties in the behaviour of a virtual spider robot
Using a virtual spider robot, we studied hypotheses about the weaving behaviour of orb spiders. Our model spiders built virtual webs that mimicked perfectly the visual architecture of real webs of the garden cross spider Araneus diadematus. The matching of capture spiral and auxiliary spiral pitch was an apparently emergent property in both types of web. This validated our interpretation of the...
متن کاملMotion Planning of Legged Robots : the Spider Robot
We consider the problem of planning motions of a simple legged robot called the spider robot. The robot is modelled as a point where all its legs are attached, and the footholds where the robot can securely place its feet consist of a set of n points in the plane. We show that the space F of admissible and stable placements of such robots has size (n 2) and can be constructed in O(n 2 log n) ti...
