Towards Autonomous Operation of Robonaut 2
The Robonaut 2 (R2) platform, as shown in Figure 1, was designed through a collaboration between NASA and General Motors to be a capable robotic assistant with the dexterity similar to a suited astronaut [1]. An R2 robot was sent to the International Space Station (ISS) in February 2011 and, in doing so, became the first humanoid robot in space. Its capabilities are presently being tested and e...
متن کاملImprovements in Ultrasonic Inspection of Resistance Spot welds
Resistance welding is an electrothermic process commonly used in Industry for joining sheet metal, particularly steel, in applications such as automobile bodies and chassis assemblies. The method is suitable for partial or total automation, and is very reliable. However, as with any process, problems can occur and inspection is therefore necessary. Although ultrasonic inspection of spot welds h...
متن کاملPrediction of cooling rate and microstructure in laser spot welds
Theoretical and experimental investigations have been carried out to examine the in uence of laser power and on time on the weld thermal cycle and weld metal microstructure and hardness during laser spot welding of low alloy steel. A transient heat transfer model that takes into account the temperature dependence of material properties and latent heat of phase transformation is employed to sim...

متن کاملUltrasonic Testing of Spot Welds in the Automotive Industry
In the modern motorcar production, more than 300 deep-drawn sheet metal parts are joined together by more than 3,000 spot welds on each car body. To check the spot welds within the framework of the quality assurance, different nondestructive test methods are available in addition to the destructive methods (tear down test, metallographic inspection): the chipping test and the ultrasonic test, w...
