... Well JAX you said it :)

Here is the latest and greatest in 3D printed gears, now with perfect roundness and accuracy.

Gears and gearboxes. What do you want for your robot?

Sometimes when your building a robot you will need gears. Although there are plenty of ready made gearboxes on the market they will not always fit your needs. I have been looking at puting together a collection of gears, shafts and even small bearings so that you can build you own gearboxs.

I started off with the green bevel gears shown below, they have big, strong, chunky teeth that are hard to break. These allow you to have a 90° output.

Polycarbonate 90° bevel gears with aluminium mounting brackets

When you build robots, sooner or later you will need a 90° bend in a drive shaft. Crown gears are fairly common but the teeth are relatively small and strip easily.

DAGU have now produced some relatively small, polycarbonate bevel gears to help solve your gear train problems. Unlike crown gears, bevel gears have a longer, tapered tooth that is much stronger and harder to strip.

Gears in Sketchup

In robotics, you  usually want more torque or speed out of your motors.

Tamiya Twin motor gear box

Hi guys 

I have a question 

Does the tamiya twin motor work with the L293D Motor Driver IC

I am going to connect it to a picaxe would it work.

Sprockets and Gears

Where are some good online stores to buy sprockets, gears, etc. from? In small and large sizes.

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 :)
