How about climbing down? Oh, wait. I called up the schematics again. Variable Attachment Surface Tension. Wow, these people sure love their acronyms. I visualized the roamer climbing down the shelf. A window popped up in my field of vision which allowed me to see through the roamer’s viewpoint. The roamer walked straight down the wall. The VAST system provided a secure grip. In seconds, I had the roamer up the table legs and onto the table.
