Canada arm question
Jeff Findley explained :
In article mn.f3bc7dc5cd6e6712.127094@snitoo, says... I'm not sure if alternate end effectors have been implemented for RMS or SSRMS. The capture hardware is pretty much the same. What's different is that SSRMS includes power and data connections in both the arm end effector and in the ISS grapple fixtures. This not only allows power and data to flow to complex tools like Dextre, but it also enables the SSRMS to literally "walk" from one power/data grapple fixture to another on ISS. Since both ends of the arm are identical, it doesn't matter which end is grappling ISS and which end is grappling something else. SSRMS (Canadarm2) http://www.asc-csa.gc.ca/eng/iss/canadarm2/default.asp Dextre http://www.asc-csa.gc.ca/eng/iss/dextre/ Swapping out end effectors for different tasks is what my comment was about, and I should have remembered Dextre because a big deal was made about it when it was sent up! /dps -- Who, me? And what lacuna? |

The end effector stays on the SSRMS (it's not swapped out). It does, however have the ability to "grab" other devices, like Dextre, which can then be controlled through the power/data lines which are connected through the end effector.
