Ana BBot

Inspired by the book Vehicles, Ana BBot is a sophisticated Braitenberg robot -- a robot controlled by an analog neural network. On board electronics implement a collection of simple McCullough-Pitts neurons that can be configured to give the "Braitenbot" a number of simple behaviors. These include "fear" (obstacle avoidance), "love" (object attraction), "searching", and "schooling". Braitenberg vehicles 1 through 6 can be implemented on this robot.

In terms of hardware, Ana has two analog range sensors and two analog light intensity sensors. These can be connected, optionally through up to six neurons, to two analog wheel motors. All "programming" is done through jumper wires which connect analog signals from some source to another destination. No separate computer or downloading is necessary -- configuring the neural network is deliciously hands-on and intuitive. Moreover, you can watch the input and output signals vary at each level of neural circuitry using the built-in meters. This provides a uniquely direct insight into the functioning of the creature.

Features

• Two Range Finders - narrow angle proportional distance sensing from 4" (10cm) to 18" (45cm)
• Two Light Sensors - proportional visible light detection with adjustable gain
• Reconfigurable - sensors can be unplugged and replugged in numerous locations around the body
• Dual Wheel Drive - bidirectional smooth speed control of each side of the vehicle
• Six Analog Neurons - include multiple summing excitatory and inhibitory inputs
• Adjustable Somatic Bias - trimpot can be used to set response range or invert the signal
• Selectable Synapse Strength - several different wire colors for 1x, 2x, and 3x coupling of signals
• Four Thresholding Units - great for simulating digital logic or adding hysteresis
• Two Bargraph Meters - monitor the strength of signals at the input and outputs of neurons
• One Bipolar Meter - measure the somatic potential of a neuron above or below ground state
• Replaceable Batteries - runs for several hours on four AA rechargeable batteries (not included)
