Great video! This thing is awesome!
What servo you are using. Where did you get it? And how strong are they? I am looking at making a remote control jetski/boat for my 2 year old and need something can handle the thrust of a jet pump.
Second question is what are you using for video that can transmit a mile?!
Keep the pictures and videos coming!
Thanks! RE: Servo/steering -I chose to go with a linear feedback actuator as they're very strong and durable. It has a potentiometer similar to a servo where it returns to center after extending/retracting. The Firgelli actuator I'm using has 150lb dynamic force, 300lb static. Very strong but the downside is speed with these. A 2" 150lb actuator moves at roughly .5"/sec. This is plenty fast for my application but not ideal for a fast moving vehicle. Typical servos (HiTec, etc) are faster but are prone to stripping and linkages failing under load/rough terrain. I'm still tuning the steering but so far it's worked out pretty well. Sure, you could mount one on a boat for rudder control but if you have the option I'd look into differential thrust (use two motors independently to steer). The Syren controller I'm using now actually has this feature (think of how a tank moves).
RE: Video - A mile is no problem. I've sent fixed wing FPV rigs beyond 12miles. Both the video and control systems we use are capable of 20-30miles in clean environments. Line of sight is still needed for our links so it becomes much more challenging sending a ground vehicle out far due to RF blocking structures (trees, walls, metal, concrete) and the fresnal zone. The frequencies I'm using on this rig (433mHz/rc, 1280mHz/video) have excellent penetration qualities. Higher video frequencies such as 5.8gHz don't penetrate well and aren't ideal for ground vehicles.
@Rob -Top speed of Rover? 8-10mph currently as it's a... Rover
It can drive on its own, navigate around objects on its own, and find its way back home after a mission. There's a few applications I have in mind, none of them need speed. I do need more torque with the 40ah batts though (heavy) and would love to hear some suggestions.
