MIT "happy board" like shield for arduino I'm working with the robotics lab at the university to try and find a replacement for the obsolete Handy Board.

We're considering purchasing arduinos because of their ease of use but we can't seem to find shields with compactly integrated capabilities as the handy board (DC motor outputs, analog/digital inputs and a physical interface such as knobs and buttons).

We did consider purchasing expansion boards but the final product would be too bulky.

Here are the complete specs:


  
  Allow direct control of at least 4 DC motors
  Accept digital and analog sensor inputs
  Simple UI (LCD, buttons/knobs)
  Be as compact as possible (including the batery)
  


Does any one know if such a thing exists?
It sounds like you're looking for the Board of Education Shield (for Arduino) 


  Key Features:
  
  
  17 row x 2 column breadboard for convenient circuit-building  
  Headers for power (Vin, 5 V, 3.3 V) Ground, Digital I/O and Analog In
  are brought adjacent to the breadboard    
  Onboard 5 V regulator supplies up to 1 A, great for robotics and
  animatronics applications  
  Onboard 3.3 V regulator supplies up to 200 mA for project circuits and
  accessories, such as XBee modules  
  4 servo ports with power selection jumper for regulated 5 V or Vin
  (Arduino's supply voltage)  
  3-position power switch for power header only or power header + servo
  ports     Board reset button resets the Arduino  
  Supply indicator LEDs for breadboard and servo power
