I currently need a setup so that I can remotely control a motor with a pulley on it so that it moves something along a track via two pulleys, one at each end and a either a wire or rope.
I am completly new to this so most things you mention to me will be new, I will have a rc transmitter and receiver(futuba) to control it with (havnt got yet, still looking), but need a speed controller, motor, pulley and whatever shafts/bearings are needed. Needs to be fast but quiet.
an easy way to do tis is to make a servo continuous rotation, its cheap most of the time, relativley quiet and easy to set up motor controller built in
im not totally sure if the reciever will be able to drive it but it might be, ask one of the RC guys here or wait for them to respond
BBlalock, but then he would not be able to accuratley place the load somewhere in the loop and it would be a pain to plug/unplug the power to the motor
you wouldn’t be able to control the speed of the pulley either
wynnefraser-wat exactly are you using this for? wat kind of loads will the pulley be moving? we need more details to give you further advice
The is basicly what I plan on doing. The reason I need a RC system, that I already need for this project is so that it can be wirelessly controlled. I have already order 2x Hitec servos, continuous rotation but I was thinking I would need more power to drive the buggy along the tracks. The buggy is approx 2ft x 1ft is size, on top of it will be mounted a camera pan/tilt head with a Canon XL1 (approx 3kg). Should all come in under 10kg…
There will be a battery on the buggy to drive the two servos used to drive the pan/tilt head & for the camera and either a battery, or mains connection/adaptor at the end for drive. The speed of the pulley needs to definetly be variable.
What would be the best way to drive the pulley? Servo with gear/chain to pulley with the wire in it, servo mounted pulley or any other ideas?
wow 3 kg…that is a lot of weight…btw u should have waited for some of the more experienced guys help on this before you got the servos, it was only a suggestion, and 3 kg a LOT of weight
i wish you had waited for another opinion about the servos i dont want you to have spent money on my opinion and have it not work
EDIT: well on a better note, u can mount the platform u want to be moving onto guide rails which will make the load much easier to bear and u can use chains and sprockets to drive the platform
btw, u thought i meant to use the servos to drive the rover?
all the pan/tilt head is fine, its just the drive I need help with…
yeh I did. looking at it now, it could be done easily. a sprocket on the servo to a small bike wheel(used as pulley) at one end and a free-wheeling one at the other.
the buggy will be mounted on two rails (aluminium pipe approx 50mm) so the weight should be easier to pull along than if it was by itself.
ohhhh, i thought u mean as in the pulley system was on a rover and the rover wheeled around, in that case you might want something more powerful than servos, i wish i knew the extent of your situation before i suggested the servos, yes they are easy to control and all but they lack power compared to motors
EDIT: as a concern to the power issue, you will probably want to gear the servo down though through the pulley, although u will lose some speed it will pull the rover along easier, could we have a lnk to the servos you bought?
I would like the buggy on the tracks to move at least 15-20kmh when possible (long enough track etc), but how would I setup a pulley at one end and a motorized pulley at the other. I want to use the HSR-5995TG servo from Servocity modified to travel continuously to somehow power the pulley so that I can easily wirelessly control it like I am with the buggy and pan/tilt. Any ideas?
you will need something faster then a servo my friend, think motors in this case, and its 10 kg u said, correct? i would go for a powerful motor that u would be able to gear for speed
so how would you recommend I do it? I need smooth motion from still to fully going then back down again using a remote control receiver/transmitter as will be used on the pan/tilt. Yes at max weight it should be about 10kg but that is on a track with not much friction.
You have a project that appears to be outside the scale of normal servo operations. Starting and stopping a ~22 pound object which will be moving at up to 17 feet per second will require some very heavy duty equipment. You don’t mention the travel distance which in itself could be an issue. Not saying it can’t be done, but you should expect to be spending a lot of $$$ to get it done.
i dont want you to have spent money on my opinion and have it not work
