Master/Slave Bicore
From BEAM Robotics Wiki
A coupled pair of bicore oscillators (One master and one slave), forming a nervous network that is generally used as the primary control circuit of a two motor walker

[edit] Master Bicore
A Master Bicore is typically a Suspended Bicore, the ouputs of which are connected to the resistors of a second bicore, thus enslaving the cycle timing of the second (or Slave Bicore) to that of the Master Bicore.
[edit] Slave Bicore
A Slave Bicore is similar to a Grounded Bicore, except that rather being connected to the ground, its resistors are connected to the outputs of a Master Bicore. It is therfore enslaved to the cycle timing of the Master Bicore. . Although it will cycle at the same frequency as the Master Bicore. the phase of its cycling will vary from that of the Master Bicore. .
Typically the capacitor and resistor values of a Slave Bicore will be matched to those of its Master Bicore. , resulting in and approximately 90 degree phase difference. However the phase relationship can be modified by changing the value of the resistors used between the two bicores.
