Sharing Pins

So I had this idea the other day about how to involve a whole class in a robotics project using just one Basic Stamp (or other microprocessor). First I would come up with a really cool scenario around which we would build our project. Something like "you are going to send a robot to Mars. You will need to collect data to send home, and be mobile to get a look at your surroundings. Design a robot that will best accomplish these goals." Then, based on that initial scenario, determine the different tasks the robot will need to accomplish and divide the class up into groups for each task. These tasks might include, navigation, video transmission, temperature collection, and terrain measurement. Once these groups have been defined, divide up the pins on the basic stamp between the teams so that they know what they have to work with. Those allotments can be adjusted to best fit the class' overall needs. Then working together as a whole class, you fit together all of the groups into a single functioning robot. I think this would be a lot of fun. The whole class would have an invested interest in the success of the robot. I think it is something that I will try out when I begin teaching next year.
