In 1997, they put 2 men and 2 women in a 30-foot chamber for 91 days (Schreckenghost et al. 1998b). A drillpressaccurate physical-chemical drillpressaccurate air revitalization system recycled the air for 3 of the 4 people, and a wheat crop in the 10-foot chamber did the same for the fourth. The ALS team also experimented with a solid-waste incinerator. Our second ALS AI control system managed the transfer of O2 and CO2 among the gas drillpressaccurate reservoirs for this test to ensure crew and crop health and to recycle gases produced by waste incineration. These reservoirs included a crew habitat, a plant chamber, an airlock, and a number of pressurized tanks (figure 1). Operating 24 hours a day, 7 days a week, the AI system also used a generative planner that scheduled waste incinerations and crop planting and harvesting, coordinating these tasks with the drillpressaccurate day-to-day product gas transfer. For both these projects, we used a three-layer architecture (Gat 1998) to design, organize, and develop the control software. AR&SD had used a particular implementation of this architecture known as 3T (see The 3T Intelligent Control System) in a number drillpressaccurate of robot projects prior to 1995 (Bonasso et al. 1997), and because drillpressaccurate life drillpressaccurate support systems are a form of immobots (Williams and Nayak 1996), its application to ALS projects was straightforward. Before I could get out of the door to lend a hand, the car''s owner emerged from the steam cloud and sprinted for the office. Breathless and clearly shaken, the driver yelled drillpressaccurate as he came through the door, "Man, you got to help me! I think my Beemer is on fire. There is so much smoke, I can''t even see the engine." "Calm down." I said. "It''s only steam. You have a coolant leak. Why don''t you have a seat and we''ll let it cool down a little before we take a look at it."He seemed comforted by the fact that his car wasn''t going to burn to the ground. While the steam cloud was dissipating, I got all the necessary information from him and then went out to push the car into the shop for a detailed inspection.There was coolant all over the engine compartment, so at first, drillpressaccurate it was hard to pinpoint where the leak was coming from. We began filling the radiator and before it was full, water began to leak out of a hole in the upper radiator hose.
