 The control mechanism of a BEAM robot is a set of analogue circuits which are broadly biologically inspired, and can be connected together to provide fixed control signals (for tasks such as moving a multi-legged walker) or have sensors integrated into them to provide a link to the outside world. There is a distinctive language developed for the construction of these circuits, which I'll attempt to explain a bit of below. The control mechanism of a BEAM robot is a set of analogue circuits which are broadly biologically inspired, and can be connected together to provide fixed control signals (for tasks such as moving a multi-legged walker) or have sensors integrated into them to provide a link to the outside world.

 These bicores are the workhorses of BEAM robot brains, and are used to provide oscillating signals which can be controlled from other Nv neurons, or directly from sensor input. These bicores are the workhorses of BEAM robot brains, and are used to provide oscillating signals which can be controlled from other Nv neurons, or directly from sensor input.
