Test Phase #1 - with Amphibious attachment
Initially the boats are put through a indoor test on a custom built amphibious attachment to the boat.
This attachment (patent pending) allows out engineers to fully test the steering of the boats without getting their delicate feet wet.
Once we are sure that the boats perform perfectly on land we are ready to take them to the water.
Test Phase #2 - in the pool
The second phase of testing involves taking the boats to the local pool to see how they go. Swimming pools give ideal conditions for the these early testing for a number of reasons. Firstly, without annoying environmental factors like wind and strong currents the steering seems to work perfectly. Secondly, with few spectators there is little embarrassment when everything thing goes wrong. Thirdly, if (or perhaps when) everything does go wrong, the water is clean enough for one of the
If the boat passes testing phase #2 we can take it outdoors in testing phase #3.
Test phase #3 - at Panther Hollow lake
Next, we take the boat out to local Panther Hollow lake. This lake, which is about 70 metres wide, gives great opportunity for the GPS and wireless testing of the boat to occur. The lake provides fantastic outdoor conditions and is only a short work from the Robotics Institute. A fishing line is tied to the rear of the boat for when the fan inevitably stops working.
Test phase #4 (optional) - in the flood
Sometimes we get unlucky and sometimes we get lucky. One day last week, when the basement of the CMU Robotics Institute flooded, we got lucky. Rarely do we get the chance to test the boats in real life flood conditions. Our engineers were very excited and quickly deployed a boat on a reconnaissance mission. The results were great and there were high fives and back slapping all round.
As you can see, a key part of Field Robotics is working in the field (the other part being robots). All of these tests have been designed to put the boats through a variety of different conditions in order to bug fix. Hopefully, as the tests get more and more difficult the boats will continue to perform at or above what is expected.
