I realise that servos are not the same as motors, but my question is which would last longer under similar conditions.
Also can someone PLEASE clear up for me, what exactly I need to drive 9V motor from an ARDUINO board. Please post a link to a product if possible for the part. Shop is immaterial I just want to see what the sucker is and what it looks like.
When a servo runs adjusted for continues rotation mounded on a robot... it's kinda hard to find an object so hard to to immediately stop the servo... and shock will be adsorbed some way....What kills servo is an extreme command.... Which means, having the servo go all the way fast forward, and immediately order it tobreak and reverse with full speed.... I did that test on a sub - micro servo with almost no load, only to find that it broke down after some hours testing.... which was quite disappointing...So what really feels like being the magical word is..... RAMP UP speed... Don't accelerate or brake on full throttle or brake.....
To interface these motors with Roboduino, I am working on an I2C motor controller module. This module will have it's own microcontroller on board and a motor driver (H-bridge). You can connect the H-bridge directly to the Roboduino for simple motor control. But I need to count the encoder pulses, use smooth ramp up and ramp down speed, keep track of traveled distance, that's why I use a second microcontroller just for this module.
