Servo trouble

Hi Royston,

Sometimes it is hard to know where to begin, because the question could be interpreted in many ways. It may take up days of your time to reach the correct answer.

This was an interesting site just for occasionally referring to (I check it from time to time). If I'm asking a question on forums I'll often pause and then maybe delete and re-type the whole thing:

However probably nowadays it should also state that where possible a picture/diagram can also say a thousand words.

Here is the full explanation.

   1)Why are you using servo?

Ans:It is because in my project I would like to build a transportation jet. The load I want to carry is 15-20kg. A very powerful motor drain all the amps of the battery within no time. So I thought a servo to lift weight. Then I realized it would also drain amps. I was not going to move the servo. It would be stationery. So why should I power it if it can lift the weight without power and signal. SO that is why I  asked the question. Hope this clearifies the problem.

A diagram will really help for us to visualize what your really trying to build, even if it is a straw man type diagram

Are you trying to make a humanoid like robot on wheels where you want to carry a load on its back ??, and is the plan to use a motor or servo (By the way there both motors and while in motion will consume similar amounts of energy as this is proportional to the work it has to do) to lift a load into place on the back of said humanoid robot

you could use a clamp to hold the load when it gets there,

as I said, a picture will help unbelievably in clarifying what your really trying to achieve as "suppose" statements makes us think you not sure.

Were not trying to be awkward, just your being a little vague

Please post a picture ?

Thanks

Royston,  thank you for your explanation.  As Peter said, a diagram would help greatly. Based on what you have given us so far:

I agree a winch servo or a servo modified for continuous movement passed 360 degrees, is the best choice for your project.  However,  it will not hold a load reliability without power.

You may need something in the box the passivity hood the load during transport. Or a transmission with a worm drive or brake to hold the load.

A diagram will confirm this.

Had problems sving a image to the discussion so had to find a similar one/s. Hope you copperate. The fomer one is like the servo clipped to the latter one. The fomer's part clips to the humanoid.(sorry for the lame explanation).The latter will be the rectangular one with the box. Only a different. Once I figure a way to upload picture I will try to.

Goes to a whole new page and in the url shows the file location and displays the picture. What next?

Select the picture and press "Insert Picture" lower right side of the pop up.

In this, the top part is what I want to hold heavy object. I want to use servo under the lower frame to hold the top one. If I don't power the servo, will the frame hold or servo fail? I don't want to load or anything. Just hold the weight on the servo without power.

Can someone make a tutorial for loading custom pictures. My dosen't load.

Hi Royston,

Will the servo be used to tip load bed like a dump truck?

If I understand it...

When the load bed is flat and inactive, it could simply rest on fixed "stop" posts, taking the load off the servo.

When the servo needs to move the load bed, the load bed would simply lift off the stop post(s) and hinge up.

The servo is stationery, no tipping, no loading. The thing is that I'm using it to hold load since the motors are brushed. Yo the servo will be kept underneath and I want the servo to carry the weight without transferring to the load to the motors/frame(since all the weight is absorbed by the gears). You all are a long way from my point I've noticed.I prefer you ask everything to clear your mind to the point.

Greetings, 

do you have a drawing the the load plate removed showing how the servo is connected to the vehicle.  That would help. The way servos are designed , I don't see it holding the load plate stationary without help such as a transmission or a support that can be moved out of the way when the load is to be moved.
