Pool-Playing Robot

Deep Green is pool-playing robot created by students at the robotics laboratory of Queen’s University in Canada. Students have worked on it for the past three years, gradually improving its abilities against human opponents:

The system is currently playing at a better-than-amateur level. One current weakness, however, is with the break. The special purpose end effector is powered by a linear electric actuator, which can reach speeds of up to 3 m/s. For a strong break, however, a cue speed of ~ 15 m/s is required. The objective of this project is therefore to design an auxiliary subsystem for the end-effector to be used exclusively for breaks. The subsystem could make use of the current cue, or it could append an additional cue to the end-effector. It is likely that the subsystem will be actuated pneumatically, although other options may be considered. The subsystem must also be compact enough so as not to interfere with the other elements of the end-effector.
