CURATORIAL READING
Why it is here
The Science Museum Group records a photoelectric cell, movement around floors, obstacle and slope avoidance, and different responses to moderate and bright light. The object makes an early cybernetic argument tangible: a few feedback relationships could produce behaviour that looked richer than any single response, without demonstrating learning, deliberation, or general intelligence.
Evidence boundary
Do not identify this catalogue entry as an original Elmer or Elsie. A 2008 University of Bristol account distinguishes a surviving original at UWE from a replica in the Science Museum, while the current catalogue dates L2000-4441 to 1950–1952 and credits UWE Bristol; these records do not fully resolve the object's identity or current display status. The catalogue image is not reproduced because its CC BY-NC-SA licence restricts commercial use.
