If it needed to go to the tail to actually drive, why do you think the tail will swing over if you drive into it and it is angled towards the ground? Surely you would just be digging some lines where your weapon is ratteling around infornt of you?

The TAIL trails behind ...the action of stopping the drive wheels causes the tail/weapon to arc over and strike the opponent in front.

but once its on the front and no longer on the smooth surface and now pointing downwards, wouldnt it then try to arc below the robot when you put it into forwards drive and make it catch on the arena floor? Im proberly wrong with this but its just my amatuer physics kinda annoying me.

No, if the weapon would try to push up the robot, youll lose traction, and therefore the force needed to trow the robot over the weapon.

With the weapon in front:-
The action of driving gently foward will cause the weapon to try to lift .....hard acceleration should make it whack back to behind the bot.
Theres an IF to go with the above.....
IF the balance between the weapon weight/length exceeds the ability of the motor drive torque to raise it ......then it will tend stay in front or behind.
EDIT:- Hard decceleration adds an extra inertia factor.

I see, interesting stuff Physics. And my english if getting much better with all this typing . Last question, If I weld 2 gears on each end of the axle, would this be enough of a reference which would let the wheels turn instead of spinning uselessly?

?

Please give any feedback, consturctive hopefully or otherwise.

Think about driving the wheels around the motor and batts or should you drive the wheel,batts motor etc around the axle?

I dont understand, do you mean mounting the equipment inside the wheel and not attacked to the wheel but the axle?

Theres a hotmail / messenger link on my profile if you wish to chat sometime...but its time for me to log off now.

I dont blame you, talking with the resident idiot (I mean me) can be frustrating.

IF you have a tail/weapon of some sort attached to the axle....Yes.

Stinger is mainly produced from stainless steel. It has 2 identical wheels with all the workings mounted inside. The wheels drive round a fixed axle which has the tail weapon attached through a friction clutch. Structure and protection are provided by 3mm thick spun steel domes and and the Kinetic Energy of this rotating mass is transferred into the tail to make a substantial weapon

Stingers weapon is its tail. This weighs 6Kg and is made from steel which has been sharpened and tipped with Stellite. The tail has no actuator, but is driven by inertia from the wheels. When the motors are stopped, the wheels continue to roll so the transmission turns the axle which transfers their momentum into the tail. When the motors are reversed from full speed, the tail slams overhead with the force of a 14lb bowling ball being dropped from 60 feet!

Perfect! Thank you for copying that information from, i assume, the stinger website. The silly college conputers will not let me access it for some reason.

The Stinger site no longer exisits .. In your other thread I gave a link to the Way back machine......this engine archives websites.....it has a copy of the old Stinger sites sadly without pictures.
