A Printer’s Hat is very easy to make. Even little children can learn how to fold it very quickly.
It is made from eco-friendly newspaper, fully biodegradable and has many many uses. It makes a super paper plate for chips and munchies at a picnic or at a campsite. Its great for holding soil for seedlings, lined with a plastic bag it can hold water, and painted or plain, it makes an attractive hat!

Now that ERP1 is up and running, it needs to be able to fix its position and report this back over the wireless data link. I plan to develop a simple Kalman filter to estimate ERP’s position, but to do this, I need two things…..
(a) An Action Parameter. This will be in the form of a motion vector. Direction will come from a digital compass and Magnitude from a wheel mounted optical encoder.
(b) Data Update. This will the estimated position of ERP1 obtained from an external fixing system such as the popular Global Positioning System (GPS).
