legacy


Since the late19thcentury, ABB has built a lasting reputation for safe, reliableand energy-efficient transportation in the alpine region.

In the case ofthe world-famous Jungfrau Railway, a 9-kilometer cog railway that beganoperation in 1912, ABB was responsible for the electrification that made theroute possible. Today, ABB technologies still ensure that the Jungfrau Railwaysafely carries more than a million passengers a year – even during heavysnowfalls – to the Jungfraujoch, which at 3,454 meters above sea level isEurope’s highest train station.

And the world’ssteepest funicular railway recently went into operation in Stoos in the SwissAlps, a 1.7-kilometer route whose two 136-passenger cable cars are powered byhigh-efficiency electric motors designed and built by ABB. The company alsosupplied other key components for the system.

Robonaut’s hands set it apart from any previous space manipulator system. These hands can fit into all the same places currently designed for an astronaut’s gloved hand. A key feature of the hand is its palm degree of freedom that allows Robonaut to cup a tool and line up its long axis with the roll degree of freedom of the forearm, thereby, permitting tool use in tight spaces with minimum arm motion. Each hand assembly shown in figure 3 has a total of 14 DOFs, and consists of a forearm, a two DOF wrist, and a twelve DOF hand complete with position, velocity, and force sensors. The forearm, which measures four inches in diameter at its base and is approximately eight inches long, houses all fourteen motors, the motor control and power electronics, and all of the wiring for the hand. An exploded view of this assembly is given in figure 4. Joint travel for the wrist pitch and yaw is designed to meet or exceed that of a human hand in a pressurized glove. Page 2 Figure 4: Forearm Assembly The requirements for interacting with planned space station EVA crew interfaces and tools provided the starting point for the Robonaut Hand design [1]. Both power and dexterous grasps are required for manipulating EVA crew tools. Certain tools require single or multiple finger actuation while being firmly grasped. A maximum force of 20 lbs and torque of 30 in-lbs are required to remove and install EVA orbital replaceable units (ORUs) [2]. The hand itself consists of two sections (figure 5) : a dexterous work set used for manipulation, and a grasping set which allows the hand to maintain a stable grasp while manipulating or actuating a given object. This is an essential feature for tool use [3]. The dexterous set consists of two 3 DOF fingers (index and middle) and a 3 DOF opposable thumb. The grasping set consists of two, single DOF fingers (ring and pinkie) and a palm DOF. All of the fingers are shock mounted into the palm. In order to match the size of an astronaut’s gloved hand, the motors are mounted outside the hand, and mechanical power is transmitted through a flexible drive train. Past hand designs [4,5] have used tendon drives which utilize complex pulley systems or sheathes, both of which pose serious wear and reliability problems when used in the EVA space environment. To avoid the problems associated with tendons, the hand uses flex shafts to transmit power from the motors in the forearm to the fingers. The rotary motion of the flex shafts is converted to linear motion in the hand using small modular leadscrew assemblies. The result is a compact yet rugged drive train. Figure 5: Hand Anatomy Overall the hand is equipped with forty-two sensors (not including tactile sensing). Each joint is equipped with embedded absolute position sensors and each motor is equipped with incremental encoders. Each of the leadscrew assemblies as well as the wrist ball joint links are instrumented as load cells to provide force feedback. In addition to providing standard impedance control, hand force control algorithms take advantage of the non-backdriveable finger drive train to minimize motor power requirements once a desired grasp force is achieved. Hand primitives in the form of pre-planned trajectories are available to minimize operator workload when performing repeated tasks.

“Today, it isall about making advancements in terms of energy efficiency,” says UeliSpinner, Head of Sales, Key Accounts & Service ABB AG, Switzerland. “Butalso where support, maintenance and service are concerned, we are the preferredpartners of cableway operators.’’

 1 Introduction

The requirements for extra-vehicularactivity (EVA) onboard the International Space Station (ISS) are expected to beconsiderable. These maintenance and construction activities are expensive andhazardous. Astronauts must prepare extensively before they may leave therelative safety of the space station, including pre-breathing at space suit airpressure for up to 4 hours. Once outside, the crew person must be extremelycautious to prevent damage to the suit. The Robotic Systems Technology Branchat the NASA Johnson Space Center is currently developing robot systems toreduce the EVA burden on space station crew and also to serve in a rapidresponse capacity. One such system, Robonaut is being designed and built tointerface with external space station systems that only have human interfaces.To this end, the Robonaut hand [1] provides a high degree of anthropomorphicdexterity ensuring a compatibility with many of these interfaces. Many groundbreaking dexterous robot hands [2-7] have been developed over the past twodecades. These devices make it possible for a robot manipulator to grasp andmanipulate objects that are not designed to be robotically M. A. DiftlerAutomation and Robotics Department Lockheed Martin Houston, Texas 77058 diftler@jsc.nasa.gov Fax: 281-244-5534 compatible. While several grippers [8-12] havebeen designed for space use and some even tested in space [8,9,11], nodexterous robotic hand has been flown in EVA conditions. The Robonaut Hand isone of several hands [13,14] under development for space EVA use and is closestin size and capability to a suited astronaut's hand.

预计国际空间站(ISS)上的车外活动(EVA)要求相当可观。这些维护和建设活动是昂贵且危险的。宇航员必须在可能离开空间站的相对安全之前进行广泛的准备,包括预先呼吸太空服空气压力长达4小时。一旦在室外,机组人员必须非常谨慎,以防止损坏宇航服。美国国家航空航天局约翰逊航天中心的机器人系统技术处目前正在开发机器人系统,以减少空间站人员的EVA负担,并且服务于快速反应能力。一个这样的系统,Robonaut正在设计和建造,以便与只有人机界面的外部空间站系统接口。为此,Robonaut手[1]提供了高度的拟人灵巧性,以确保与许多这些接口的兼容性。在过去的二十年中,已经开发出许多破纪录的灵巧机器人手[2-7]。这些设备使得机器人操纵器能够抓住和操纵未被设计为机器人的物体兼容。虽然有几个夹具[8-12]设计用于空间使用,有些甚至在太空中进行了测试[8,9,11],但没有灵巧的机器人手在EVA条件下飞行。 Robonaut手是空间EVA使用中正在开发的几只手之一[13,14],它的尺寸和能力最接近适合宇航员的手。

 2 Design and Control Philosophy

The requirements for interacting withplanned space station EVA crew interfaces and tools provided the starting pointfor the Robonaut Hand design [1]. Both power (enveloping) and dexterous grasps(finger tip) are required for manipulating EVA crew tools. Certain toolsrequire single or multiple finger actuation while being firmly grasped. Amaximum force of 20 lbs. and torque of 30 in-lbs are required to remove andinstall EVA orbital replaceable units (ORUs) [15]. All EVA tools and ORUs mustbe retained in the event of a power loss. It is possible to either buildinterfaces that will be both robotically and EVA compatible or build a seriesof robot tools to interact with EVA crew interfaces and tools. However, bothapproaches are extremely costly and will of course add to a set of spacestation tools and interfaces that are already planned to be quite extensive.The Robonaut design will make all EVA crew interfaces and tools roboticallycompatible by making the robot's hand EVA compatible. EVA compatibility isdesigned into the hand by reproducing, as closely.as possible, the size,kinematics, and strength of the space suited astronaut hand and wrist. Thenumber of fingers and the joint travel reproduce the workspace for apressurized suit glove. The Robonaut Hand reproduces many of the necessarygrasps needed for interacting with EVA interfaces. Staying within this sizeenvelope guarantees that the Robonaut Hand will be able to fit into all therequired places. Joint travel for the wrist pitch and yaw is designed to meetor exceed the human hand in a pressurized glove. The hand and wrist parts are  sizedto reproduce the necessary strength to meet maximum EVA crew requirements.Figure1: Robonaut Hand Control system design for a dexterous robot handmanipulating a variety of tools has unique problems. The majority of theliterature available, summarized in [2,16], pertains to dexterous manipulation.This literature concentrates on using three dexterous fingers to obtain forceclosure and manipulate an object using only fingertip contact. While useful,this type of manipulation does not lend itself to tool use. Most EVA tools arebest used in an enveloping grasp. Two enveloping grasp types, tool and power,must be supported by the tool-using hand in addition to the dexterous grasp.Although literature is available on enveloping grasps [17], it is not asadvanced as the dexterous literature. The main complication involvesdetermining and controlling the forces at the many contact areas involved in anenveloping grasp. While work continues on automating enveloping grasps, a tele-operationcontrol strategy has been adopted for the Robonaut hand. This method ofoperation was proven with the NASA DART/FITT system [18]. The DART/FITT systemutilizes Cyber glove® virtual reality gloves, worn by the operator, to controlStanford/YPL hands to successfully perform space relevant tasks. 2.1 SpaceCompatibility EVA space compatibility separates the Robonaut Hand from manyothers. All component materials meetoutgassing restrictions to prevent contamination that couldinterfere with other space systems. Parts made of different materials aretoleranced to perform acceptably under the extreme temperature variationsexperienced in EVA conditions. Brushless motors are used to ensure long life ina vacuum. All parts are designed to use proven space lubricants.

与计划的空间站EVA乘员接口和工具交互的要求为Robonaut手设计要求提供了起点[1]。

操纵EVA乘员工具需要力量(包络)和灵巧的抓握(指尖)。某些工具需要单手或多手指动作,同时牢牢抓住。 20磅的最大力量。并需要30英寸磅的扭矩来拆卸和安装EVA轨道可更换单元(ORU)[15]。

所有EVA工具和ORU必须在发生断电时保留。可以构建兼容机器人和EVA的接口,或者构建一系列机器人工具来与EVA机组接口和工具进行交互。然而,这两种方法都是非常昂贵的,并且当然会增加一套空间站工具和接口,这些工具和接口已经计划得相当广泛。 Robonaut设计将使机器人的手EVA兼容,从而使所有EVA机组人机界面和工具机器人兼容。通过尽可能地再现适合宇航员手和手腕的空间的尺寸,运动学和强度,将EVA兼容性设计在手中。手指和联合行程的数量重现了加压套装手套的工作空间。 Robonaut手掌再现了与EVA界面交互所需的许多必要手段。保持在这个尺寸范围内保证Robonaut手将能够适应所有需要的地方。手腕节距和偏航的联合行程被设计为在加压手套中达到或超过人手。手部和腕部的尺寸可以重现必要的强度,以满足最大的EVA机组人员的要求。

图1:Robonaut手控系统设计灵巧的机器人手操纵各种工具具有独特的问题。在[2,16]中总结的大多数文献都涉及到灵巧的操纵。这些文献集中于使用三个灵巧手指来获得力闭合并仅使用指尖接触来操纵物体。虽然有用,但这种类型的操作不适用于工具使用。大多数EVA工具最适合用于包围式抓握。除了灵巧的抓握之外,还必须使用工具用手来支撑两种包络抓握类型,工具和力量。虽然文献可用于包络抓握[17],但它并不像灵巧手那样先进。主要的复杂性包括确定和控制涉及包络抓握的许多接触区域的力。虽然自动化包络抓握的工作仍在继续,但Robonaut手已采用远程操作控制策略。美国国家航空航天局DART / FITT系统证明了这种操作方法[18]。 DART / FITT系统使用由操作员佩戴的Cyber​​glove®虚拟现实手套来控制Stanford / YPL手以成功执行空间相关任务。

 2.1空间兼容性EVA空间兼容性将Robonaut手与其他许多人分开。所有组件材料均满足除气限制,以防止可能干扰其他空间系统的污染。不同材料制成的零件在EVA条件下经受极端温度变化时具有可接受的性能。无刷电机用于确保真空中的长寿命。所有零件都设计为使用经过验证的空间润滑剂。

The forearm, which measures four inches in diameter atits base and is approximately eight inches long, houses all fourteen motors, 12separate circuit boards, and all of the wiring for the hand. Y= Figure 2: Handcomponents The hand itself is broken down into two sections (figure 2): adexterous work set which is used for manipulation, and a grasping set whichallows the hand to maintain a stable grasp while manipulating or actuating agiven object.
