    Drivetrains!??!?!?!?!?!?

    ok i dont get how to hook them up i want to build a tank style driving robot but i cant find out how to make the drivetrain i want it so that is is either 4 to 6 wheel treaded or any drivetrain im going crazy all i keep getting on google is that stupid how to book i dont wanna buy a book so if u guys could plzzzzzzzzz send me drivetrain links it would be mucho appreciated and no one comment me on my poor grammer i know how to do it i just dont

    If you have Power Point you could look here:-

    http://155.212.10.234/uploadedFiles/Community/FRC/Team_Resources/Team_Resources_Assets/2006_KO_Chassis_Drivetrain.ppthttp://155.212.10.234/uploadedFiles/...eam_Resources_ Assets/2006_KO_Chassis_Drivetrain.ppt

    The simplest is a motor with a small sprocket driving via a chain to a drive wheel with a big sprocket.

      Are you sure you want to build a tracked robot? One sees few of them because they are hard to build.

        how are tracked robot hard to build a track like drivetrain has great traction

          in the arena i think tracked robots are no way near has grippy has wheeld they just do power slides everywhere , well might not be a bad idea could have drifting compitions in the arena!

            Because the drive train is far more complex than a simple wheel system. You may get more grip depending on what your tracks are made from but remember you will have to turn the robot with all that grip.

            I highly recommend you go with what is well tried and tested. Once you have a solid footing with a wheeled robot then move onto something more complex.

              well no i was going to have a tracked drivetrain um but the tracked part i was going to bolt to the rim of a flatless tire kind of like this tire but im also going to attach chain in sprocket to get torque http://www.seattlerobotics.org/encoder/200104/wheel.htmhttp://www.seattlerobotics.org/encoder/200104/wheel.htm

                Ahhh right, I think I understand now. Sorry I mis-read your first post. I thought you meant that you wanted to build a robot that used tank tracks.

                Do you mean you want to use a chain and sprocket drive train? But you arent sure how to setup the drive train to transfer the energy from the motor to the wheel?

                O and I realise that you dont like to use grammer and punctuation but it does make posts far easier to understand and it only takes an extra 2 minutes.

                  oh no i just found that site yesterday but thats how i want to do i i know tires have best traction but im not sure how to attach an axle do i attach it to the motor or do i need something in particular to attach it 2 also is this a good idea having sprocket belt and wheel drive do u get what im saying????

                    yah yah yah yah but also i dont get how to attach the wheel so that i dont break motor axle if im using a ton of torque how do i attach motor to a long axle and do u think my idea of chain and sprocket belt and wheel drive

                      Lance, I will email you a few pictures of my new heavyweight and its drive setup. I used a combination of spur gears and sprockets and chain to firstly gear down and then secondly to transfer the drive from the rear wheels to the front.

                      Sprockets work a treat but you have to line them up correctly.

                      Never attach a wheel directly to a motor. You always have to gear the wheel down so that the wheel rotates with less speed but more torque.

                      When it comes to attaching a wheel or sprocket to a shaft there are a number of options available. What weight class are you looking at building in?

                      I would not recommend either the middle or light as there are so few robots around in these classes (if any). I would recommend you start off with a featherweight (12kg) and then look to something bigger.

                        do u have an aim and yah im going for middle and i got a guy doing the electronics but i have a great plan for drivetrain i kind of get it but he said his team for school just used to attach tires to the motor but that was just hanging up hangers
