We’ve installed a sweet new blue anodized aluminum air dam on the pneumatic lid for the DOMO sample dewar (with color coordinated electric blue CPU fans). The air dam helps to draw off frozen ice crystals from the air above the liquid nitrogen when the dewar lid is open. This will hopefully prevent the ice…

DOMO used to collect data remotely for the first time.
Scott Williams, a postdoc in the Tainer group at The Scripps Research Institute, was the first crystallographer to use DOMO. Here he is kicking back and enjoying some of the fine espresso available at the beamline while DOMO mounts his samples from the custom LN2 sample dewar in the hutch. Scott screened through ~40 samples…

After determining that operating the LN2 sample dewar without a lid was going to be problematic with regards to ice accumulation in the liquid nitrogen I decided to design and install a pneumatically operated guillotine lid. Here is a nice aerial shot of the closed lid. hit the jump for details and more pics…
Today DOMO mounted its first pin from the sample dewar that was filled with liquid nitrogen. This video is pretty large so unless you are on a fast connection or have alot of time to waste trust me DOMO is finally crawling.
After two days of code wrangling, two snapped electrical cables, one crash into the goniometer, and several reconfigurations of the force sensor and gripper arms DOMO is alive. On Friday afternoon DOMO mounted its first sample successfully. There is still much work that needs to be done and many bugs to be ironed out, but…

The new PX automated sample mounting robot shall henceforth be known as “DOMO” as in Domo Arigato. Mr Roboto. It’s short and catchy, but isn’t really an acronym for anything… yet DOMO Doer Of Mechanized Operations? or Dolt whO follows My Orders? I think beer will be given to the person who comes up with…

Being the brave souls that we are we thought we would attempt to make a sample dewar without a lid. Our main concern is ice. We are concerned with the build up of ice around the rim of the dewar, but more important is the prevention of ice accumulating in the liquid nitrogen in the…
