Sariel Posted October 28, 2012 Posted October 28, 2012 I should have come up with it sooner. Building instruction: http://sariel.pl/2012/10/servo-gearbox/ Hope it helps. Quote
GoGoPWN Posted October 28, 2012 Posted October 28, 2012 (edited) Genius! I could really see this working off in a RC Car. Edited October 28, 2012 by GoGoPWN Quote
Darth Dino Posted October 28, 2012 Posted October 28, 2012 Hi wow - that is great bevause it keeps many things simple. It is that simpke that even myself understands right from the video how it works. Do you had to hold the trigger down to keep the gear in 3rd podition? Because the servor always jumps back to the neutral position - 2nd gear? Dino Quote
Sariel Posted October 28, 2012 Author Posted October 28, 2012 Yes, you have to hold the remote's lever. You can modify the remote if it's a problem, though, put some kind of a lock on it. Quote
Edwin Korstanje Posted October 28, 2012 Posted October 28, 2012 Like always a very genius and simple gearbox from your hands. Thanks Sariel i will try this gearbox Quote
dhc6twinotter Posted October 28, 2012 Posted October 28, 2012 Brilliant design there! Fantastic work! Quote
Conchas Posted October 28, 2012 Posted October 28, 2012 Excellent realization! Yes, you have to hold the remote's lever. You can modify the remote if it's a problem, though, put some kind of a lock on it. Alternatively you can use the PF Speed Remote to address that issue. Quote
timslegos Posted October 28, 2012 Posted October 28, 2012 Nice solution. Is it safe to hold the servo in one of the directions for an extended period of time? tim Quote
rm8 Posted October 28, 2012 Posted October 28, 2012 (edited) Very surprisingly. You are genious! Edited October 28, 2012 by rm8 Quote
Sariel Posted October 28, 2012 Author Posted October 28, 2012 Is it safe to hold the servo in one of the directions for an extended period of time? I imagine it was made for it. Quote
hrontos Posted October 28, 2012 Posted October 28, 2012 This is really nice solution. Even there is that gear skipping risk under high torque it is still very nice and elegant. With PF Speed remote this approach can be used as some kind of multiplexer - one input and multiple outputs selected by the position of the speed remote. Quote
Tadej Posted October 28, 2012 Posted October 28, 2012 Great, only problem is that you need 3 separate channels to drive a vehicle. Quote
SNIPE Posted October 29, 2012 Posted October 29, 2012 Nice ! I'm supervised I also didn't 'see' this design when trying to make something in LDD im busy making a similar version Quote
Blakbird Posted October 29, 2012 Posted October 29, 2012 Cool idea! The one drawback I see is that the torque of the drive motor will tend to backdrive the servo. This means that the servo needs to react the entire propulsive torque. I could imagine that a high torque motor like an XL, when under load, might force the servo out of gear. If you used the train remote, at least you wouldn't have to hold down the button to position the servo. You could dial it to where you wanted it and it would stay there. Quote
kieran Posted October 30, 2012 Posted October 30, 2012 Nice use for the Servo, Make good use of the 3 main positions using a standard remote, I like it. Quote
