Really powerfull servos

[Scorpion]

Has anyone ever made one of these?
If so, do they then just turn into normal motors due to the speed?

Basically, i want to know if you can mod a servo so it can act as a proper lifter or crusher (like panic attacks lifting spikes or razers crusher, fully controllable but strong enough to be effective).

[NFX]

Speed has nothing to do with the strength, it's the torque you want to be worried about, I think. Some of the servos in NAR AI have upwards of 5000 torques, compared to 40 for a half-decent drive motor.

Really?
CAn they opperate well as lifters then?

I think so, but Bursts are better for flipping.

[SteveM4]

I think he wants lifters...

So do I, I wanted to make a Havok bot have a lifter.

Exactly!
I'll download nar AI in a bit and see what they're like, although if they do work as lifters, I have to change panic attacks weapon motor in dsl.

Servos can't lift bots no matter how powerful they are.  Only burst motors can do that.  The torque on a servo only applies to how much weight attached to your own bot it can lift.  Also, for some reason motors are harder to lift than static components.


Of course, you CAN use tons of counterweight, but that's basically just using gravity to lift bots, not the servo.

[Scrap Daddy]

Couldn't one make a really heavy and invisible counterweight to make replicas work like real ones?

[Clickbeetle]

In theory yes... BUT:


-the closer the counterweight is to the axle, the heavier it needs to be.
-most lifters have little room between the axle and the floor.
-with very heavy counterweight (and it needs to be VERY heavy), the bot would become overweight, which would require more powerful drive, which would give it an unfair pushing power advantage, and make it harder to flip with a same-weight-class bot.

What about making servos "base=SpinMotor" with high torque and low maxspeed like the geared Beta ?

[NFX]

There'd need to be some way of stopping it from uselessly flopping back down again when it's not being powered.

Special .py ?

[NFX]

You mean a .py that would feather the button to try and keep it at a certain level?

Or, you could tweak a normal hammer motor (Geared Beta seems capable of lifting robots, Argonaut managed fine with 3 for 5000kg) and give it a smaller radius, like a 45 and 90 degree versions. I imagine they'd be able to lift bots relatively easily. You'd have to keep the button held in to hold the motor in the "up" position, but I imagine it'd be fairly simple.

A .py using an analog and different throttle values.

just have a locking axle (like servos) with a restricted Arc as a super powerful spin motor.. presto a flipper or lifter that stays open

Beta geared.

But slower. I'll make some of these for my upcoming mod.

[JoeBlo]

but do it with a locking axle to hold its position 

[Naryar]

A locking axle ? What do you mean ? Like a locked tread motor or a restricted 90/180 degree motor ?

[JoeBlo]

like the locking tread motor or a servo.. its simply a small tweak in the GMF to the axle movement object to take the free movement out of it.

if you want any further info just hit me via pm, I wouldnt mind working on a few projects with you

OK, I'll try.

I don't have and take much time towards RA2 atm, but i could. Especially that I will be on vacation one week in the end of october.
