Theoretical three-and four-axis gimbal robot wrists. Washington, D.C.: National Aeronautics and Space Administration, Scientific and Technical Information Branch, May (OCoLC) Material Type: Government publication, National government publication: Document Type: Book: All Authors / Contributors: L Keith Barker; Jacob A Houck; United States. National Aeronautics and Space Administration. The first book devoted to robot wrists, this text/reference describes the various morphologies of wrist actuators through the lavish use of photographs, and diagrammatic and isometric drawings. Displays the most significant robot wrists of the past, now is use, and under by: For example, a true three-axis robot wrist is functionally equivalent to a three-axis gimbal Four-Gimbal Robot Wrist system, where the gimbal angles represent joint an- gles, in that both provide rotational capability about Figure 9 shows operator inputs, probe-tip move- each of three mutually perpendicular axes all pass- ment, gimbal angle rates, and gimbal angles for the .   Customer Reviews: out of 5 stars 12 customer ratings; Amazon Best Sellers Rank: #, in Books (See Top in Books) # in Industrial Engineering (Books) # in Robotics (Books) #65 in Industrial Technology (Books)5/5(4).

In book: Robotics in Alpe-Adria Region (pp) Authors: A new design of spherical 3 d.o.f. wrist for robot is presented. Theoretical results are examined using six force sensors of a. Comparison of gimbal lock in the three-axis system with that of the four-axis system shows that gimbal lock can be avoided with a four-axis system provided -- 90° while gimbal lock can not be avoided in a three-axis system without restricting the vehicle's motion [3].

HAHN Automation Plastics flexible, expandable, state-of-the-art high speed 3-axis liner robots maximize your plastic injection molding robotics return on investment and help you gain competitive advantage in plastic injection molding automation.. In addition to the full range of 3-axis robots, HAHN Automation Plastics complete line of plastic injection molding robots . 3-axis robots (top entry robots) are simple to operate and maintain, and minimize energy consumption. They are also easily redeployed for automation applications on various types and sizes of plastic injection molding machines within the robot's payload and strength. According to theoretical analysis and MATLAB simulation result, this application scheme could drive four-axis gimbal system to simulate wide attitude motion of the flight vehicle rather than. The first four mechanisms (i.e., the 2DOF gimbal, the iCub mk.2 wrist, the five-bar mechanism and the six-bar mechanism) have an inherent gimbal-like structure. In this case, it becomes natural to choose the Roll-Pitch-Yaw Euler-angle parameterization for the platform orientations as it implies a straightforward geometric interpretation.
