# Does the strength of a servo motor depend on the motor or the power?

I am making a life-size robotic dog, and i am having trouble with getting it to walk as it is too heavy for my 4 micro sg servos. Can i make the servos more powerful with more power? If not i can just see if i can make the dog lighter. Many thanks

• Can you provide more information about the servos? Maybe the datasheet or the approx weight to move. Oct 23, 2020 at 21:10
• Size the load (dog) according to the power of the motors OR size the motors needed according to the load (dog). Oct 24, 2020 at 4:43
• Putting more than the rated power through any motor will cause it to overheat and become damaged. Make the dog lighter, replace the servos, or both. Oct 24, 2020 at 7:52
• I suggest you get a torque wrench and see how hard you have to turn these linkages to get it to move as fast as you want. Then buy an appropriate motor. I suggest that most of the weight will need to be batteries and motors. Oct 26, 2020 at 8:02
• life size robotic dog is meaningless ... chihuahua or great dane? ... please edit your post with a description of the actual dimensions and weight Mar 19 at 21:46
