Re: pic: Prototype Drivetrain
Nice CAD model, but physics says this design will not work too well. Also, it looks like your design is based around BaneBots gearboxes, which I would recommend against. You may consider placing those center wheels closer to the outside of the vehicle, and powering the omni wheels as well.

Re: pic: Prototype Drivetrain
Pull the wheels out to the edges. Even if you didn't realize the physics behind this, just think "if it was an advantage to pull the wheels closer together, more teams would be doing it by now." Common sense goes a long way. Also I hope you plan to drive those Omni wheels.
Other than that I can't say much since I'm not one to judge about lightening patterns and structural integrity of sheetmetal parts just yet. ![]() Last edited by Akash Rastogi : 07-05-2010 at 21:37. |

Re: pic: Prototype Drivetrain
I would advise you to drive the four omnis on the corners. Your tractive force is based off of the sum of the forces of friction on all of your wheels. With the design you have right now, you are essentially "wasting" the normal force on the corner wheels. Whatever weight you will have on those sections of the robot will not contribute to your pushing force, giving you less than what you would generally want.

I apologize if I'm making the assumption that your omni wheels are on an active suspension. But... I would be even more puzzled if you were to use a floating suspension. |
