    Hi there!

    Old question we had from the other forum: quick question, if we have passed the demonstrate AUV launch and recovery test, would we be allowed to have tethered practice with the AUV direct to shore provided our tether is long enough? This would allow for more real-time feedback and tuning of the tasks without battling the datalink.

      Hello bumblebee. We do not intend to allow shore-based, tethered operation of the AUV. All AUV operations must be conducted from the surface platform as described in the published rules.

      The nature of the underwater challenge means that it can not be placed near to the shore. This, combined with local environmental conditions and other (manned and unmanned) craft in the area presents a safety concern. The RoboNation team is exploring options to enable AUV testing.

        Aamir Qaiyumi How about a isolated gazetted area with a mock up of the rings challenge that we can test in there first?

        And yes more confirmation on the design of the rings challenge!

            bumblebee I understand your request and this is something we have discussed previously. We are trying to evaluate logistics, and implementation of such an isolated area, while ensuring we do not impede general public access to the waterway.

              Thankyou for the updated rules and requirements! There are some things that we would like to clarify, most urgently from the Kill Switch Document. First of all, we are a little confused about the separate power source. Our safety system runs directly off the main battery, meaning as long as anything on the boat has power, our safety system does as well. Since there is no need for a safety system if the rest of the whole boat has no power, is this sufficient?

              Second, We are unsure about the wireless separation requirement. We have two separate datalinks on our boat. One runs the network and all the communications for autonomy and such. The second is a safety datalink which is nothing but the Estop signal and basic RC controls. This E-stop signal is split from the control signals before the control system and that one signal is connected in hardware (See IARC-suggested E-Stop circuit) to our E-stop system and directly controls the relay current, it does go over the same wireless link as our redundant safety controls, but not through any sort of micro-controller like the rest of the signal does. Is this considered separate?

                We second embry riddle for the kill system design. We also decided to share a single power and evaluated the safety considerations with risk assessment for this as it is problematic to have to manage two different battery sources on board the system separately. In the event of a power failure event, the thrusters are killed. If power for some reason is cut off to the kill board, the default state of the contactors will deactivate the thrusters. If power or logic fails to the main system except the kill board, the kill board still has full isolated control over the dedicated wireless datalink(the radio is integrated as part of the kill board) to the wireless remote box. So we already have multiple levels of redundancy in place.

                  In addition, please release the final specifications for the combined docking/shoot challenge. And we would like to see the points break down of all the challenges.

                    We will like more information about the combined docking/shooting task as well. From what we interpret, there will still be a square structure in the middle area, where 2 opposing faces are for the docking task while the other 2 opposing faces are for the shooting task. Is this interpretation correct?

                    Will the symbols on the faces be unrepeated?

                    Is there a colored border around the holes? If not, we will like to suggest a yellow border around the holes since this color is not being used yet.

                    Thanks!

                      The question of if the shooting challenge is only the two faces perpendicular to the docks as bumblebee mentioned came up in our lab earlier this week when we were talking about orientation of our shooter. We would also like answers to the questions bumblebee raised.
