By 2001, the 4 cameras had been co-aligned and two of them had added filters. In the idle time between GRB triggers, LOTIS systematically surveyed the entire available sky every night for new optical transients. LOTIS was succeeded by another robotic telescope with a larger mirror but smaller field of view, called Super-LOTIS.
