| 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.

| The LED is a flashing type, and is used for detecting when the voltage across the capacitor reaches around 2v - then it turns on and trips the transistor into dumping all the power to the motor. The bigger the capacitor, the more charge it will store. This method is known as a FLED Solar engine. | The LED is a flashing type, and is used for detecting when the voltage across the capacitor reaches around 2v - then it turns on and trips the transistor into dumping all the power to the motor.
