I have flown the AC-ROV in different lakes, harbours and in test tanks on numerous occasions, but that would be no surprise to those that know I am a director of ROVworld Lda (Portugal) a company appointed to distribute AC-CESS products.
How does it handle?
Right out of the box it takes a bit of getting used to, but an hour or so of practice should see you to getting reasonable results on the flying front. The AC-ROV does not have the same low center of gravity as standard small ROV’s. This is because it has a fixed camera, so the camera pitch is obtained by tilting the nose up or down using the two vertical thrusters (one fore and one aft).
The balance of the vehicle allows for it to manoeuvre nose up or nose down in an almost vertical plane.
As many know, other ROV’s have a tilt mechanism on their cameras set-ups which is due to the fact that these vehicles often can only fly in a level plane, with some only having one vertical thruster mounted centrally.Screen?
Colour camera output is Colour CCD 550 line x 0.1 lux (NTSC or PAL)
VGA output is from the control unit to the included 145mm (5.7") colour LCD monitor. The image is very clear on the monitor although bright sunlight can sometimes hamper viewing, as it will with any screen.
There is also a composite video out option fitted to the topside control unit. Please visit http://www.rovworld.eu/ and look at the downloads section where you can download video examples. I’d give a direct link but as we are developing a new site (for ROVworld.eu) that may change soon but the base URL will not.
Also, we have recently uploaded a couple of in-house produced videos to our new ROVworld Lda youTube account. You can view these at: http://www.youtube.com/user/ROVworld They’ll give you an idea of image quality in murky conditions and clear test tank conditions.How long does it take to set-up?
I have seen a video where the Business Development Manager at AC-CESS set up and the AC-ROV and has it set up and in the water in around 3.5 minutes. In reality I have found that 5 minutes is easily achievable. Considering it all fits into one hand carry case (total weight 18Kg) and it will run off a small gen-set (350w required) weighing about the same, it’s very easy to get it to the work site and mobilise.best regards
