Greater than 360 Servo (not continuous)

 

There was a question in the Shout Box earlier from noise0. He wants to turn a turret with srf08 sensor and be able to rotate at least 360 degrees. But it does not have to be continuous. He can go from 0 to 360 and then reverse direction back to 360.

There were a lot of ideas including a super modified servo (http://www.01mech.com/supermodified), stepper motor, or motor encoders.

Silent (veryquietatbest) drive system for robots?

Hi folks, i'm looking for a silent or quiet drive system for my robot.

It is just a wheeled device at the moment.

I'v ordered a tamiya track and wheel set which won't arrive for a few days, and

i was wondering if anyone could tell me how quiet it is without the motors,  ie does it squeak and rattle etc.

 

i'm pretty sure the tamiya motors i'v ordered with it will make some noise as they are geared down.

 

researching this site i came across Gareth's first robot (initially mistaken for spam :)
