The main idea is to manage a simple robot from the analogue output of the XO (There are Pippy code examples that can output analogue data).

Development Stages

  • The first to do is making a simple activity that sends signals to a simple circuit connected to a couple of motors. The output could be digital or analogue.The digital output is convinient for direct aplication to dc motors, like servomotors.
  • The motors have to be joined in a simple platform, made form recyclable materials, so the cost of the construction is very slow.
  • This activity also has to be shareable by the means of the hellomesh activity.
  • In a later stage of development the little robot has to be controlled remotely.


Notes

  • Also the USB alternatives should be investigated.
  • The source code has to be visible for the children.
  • Another take on the development could be withouth the need of hardware, only the simulation process, for this a nice project to check out is [ http://pyrorobotics.org/?page=The_20Pyrobot_20Simulator Pyrobot]

Other related projects

  • This page shows one example, an XO on top of a Roomba robot vacuum cleaner. This project cleverly uses the camera to show the robot's view on a webpage; the same page allows the robot to be driven remotely.
  • USB related: Within the 1A USB power limit, a few small hobby servos could be connected and run off of the OLPC's battery. They could easily receive a pulse width signal from the headphone port, or a $1 USD microcontroller to control them via USB.
