2 or 4 servos

[roboboy12]

would it be better to go with 4 servos insted of only2

[cooldog]

depends on the robot

4 servos use more elctricity so you need more batterys but they are stronger

2 servos use less energy so you don't need alot of batterys but they are weaker

for a indoor robot 4 servos is overkill


what type of robot are you making?

[frodo]

it also depends on the terrain and power usage of your robot. eg. its like a car - 4 wheel drive on rough terrain and 4 servos for rough terrain for robots. also if the power usage of your robot is high it may be good to use 2 servos to not use as much battery power.

How are we supposed to answer questions like that?

You give no information at all about what you want as a result. No info about what type of servo's. No info about your purpose...
Next time, make sure there is plenty of information.

i thnk you ment to wuote the original first post not the reply

security out door but four servos means more off my buget

Servos will be too slow for an outdoor robot, you'll be barely crawling on the ground. I suppose you could get some high-torque servos, but for that price you can just get bigger gearmotors that will work really well.

I disagree. Look at my ERP on the MOBOT race course
It used simple HS-311 servos.

That being said, the OP (person who opened the post) told us nothing about his robot so its impossible to answer the question.

heres my design

[SmAsH]

even with that picture its still hard to say, can you atleast tell us what kind of terrain i needs, or how fast it needs to be? and if it needs to carry a payload at all?

What nice, smooth concrete that was    Outdoors usually means lawn/grass/dirt kind of stuff, and grass especially slows things down a lot. Maybe 4 high torque servos would do it, but that's a lot of money to waste, gearmotors would be cheaper.
