The Odys software from the Robosail project is alive at 9Tek.

Some time ago there was a project named RoboSail, that made competition sailing even more advanced. There technology was tested on the Syllogic (Now “9Tek Syllogic”) and several Volvo Ocean race boats with great success, but the marked was limited and the project ended. Now 9Tek got what’s left of it, and we have already moved the hart of the system, the Odys software over to a new updated hardware and software platform. We have also written a new “GPU III” module to interface with the Odys, and this week we showed that the Odys is working, and processing live data again. Stumbling and coughing at the moment, but never the less alive. We also added the MacENC charter map software that integrates well with Odys and the rest of our systems.



As this is resurge, we will replace the traditional CAN & NMEA busses, with Wireless LAN. We all agree that the CAN is more robust and closer to real time. But the W-Lan requires no cables and are way easier to use and program. The real-time issue we solve by making the Autopilot smarter so no hard real-time is need on the buss. This is the same as RoboSail did, and we hope to adapt their approach. We believe that today’s wireless-lan can be stabile enough to do this job. However this remains to be tested.

We replace all the control displays with iPads. This gives a way more flexible solution, but sunlight is a problem.

The two main computers will be MacMini computers. One computer will be running the Odys software, and the other the MacENC map software + communications etc. The two computers will both be connected to the GPU III and can act as backup system for eatch other. The ide’a is to se if one can use only Apple products, except for the embedded controller. Why? To make a final product that is hi-quality and at the same time relatively lo-cost and easy to get. And to avoid making any hardware in-house, there simply is no money in that any more.

The Autopilot will be based on the “Beaglebone” CPU board running Linux. This board got ADC, and PWM modules, together with an RC (hobby) 120Amp PWM motor controller, we can control the tiller, and the keel positions. And hopefully also the water ballast valves. Then we will use machine learning algorithms to tune the PIDs.

The GPU III, that is the sensor and network fusion module, will be based on the now famous “Raspberry PI” board, also running Linux. This will fuse all the sensors and send the result to Odys.

The system will be made so that it can be used without the Odys running (to save power or PC breakdown), but with less smartness. This is just like the RoboSail project.

The Odys software will then also get the SmartSail information from the GPU III, and by using it’s many complex filters it can gain even more knowledge of system status and thus give better feedback.
