Abstract: WALL-CLIMBING APPARATUS WITH LIQUID-FILLED SPRING-EXPANDED SUCTION CELLS ON A TRACK AND MOTION-ONLY VENTING A wall- climbing apparatus (100) carries suction cells (106) on the links of an endless track (104). Each cell has a sealed chamber filled with a liquid, a piston biased by a spring to enlarge it, a latch and a vent. A firing station releases the latch at a distance x_f from the touchdown point of the rim, with p = x_f = 0.40 * L_e, so that each cell fires only after its link lies flat and enough fired cells hold the apparatus. The vent opens only at a vent station while the track moves, so every stop, including loss of power, leaves the engaged cells clamped. A recharge station re-compresses the springs from the drive, and check valves isolate each cell. Modelling predicts a moving safety factor of 1.43 and a 42-minute hold after power loss. FIG. 1
