HEBOT by John Fitzgerald and Henry Budgett, in Hobby Electronics, November 1979 - January 1980. The Hebot chassis, aluminium shell and mechanical components were available as a kit from Remcon Ltd. "The novel feature of this system is the separation of executive and control signals. In a maximal system, up to eight pairs of motor control signals may be present simultaneously with HEBOT choosing between them according to the state of 'priority' input sense lines. A possible arrangement might be Level seven has highest priority and zero lowest priority. Assuming HEBOT was not under external control and was neither tracking nor searching then a random walk would be executed. Following any collision, priority sense input three would become active and HEBOT would manoeuvre himself out of trouble before returning control to level zero: random walk." – Hebot, Hobby Electronics, November, December 1979, January 1980.
