CRO SS FI RE

Time and again wh en men w aged w ar on each other , empi res looked to restor e the i r g lory ; count r ies

intend ed to display their mi l i tary m ight, levers w ent d ow n, gears creaked, engines roared. M achines

stood tal l and evolved wi th every instance. Dat ing back to a century, the world experienced a

massive surge in the development of war machines. A new breed of ships, batt le tanks and most

important ly ai rplanes were unleashed on each other.Ungodly technological advancements were

made. The roo ts of t odays science & techno logies go as far back as these tou gh t im es.

W hen un i form ed m en form ed ranks, machines d isp layed t he i r prow ess in suppressing the enem y

and oppressing th e i r f ront l i ne. An age w as form ed where m achines completed m en. A new

generat ion o f M ECHANICAL EN GINEERS was thus born to the wor ld . A new sphere and a new

dim ension w ere added. M achines started being used for w aging war and m aintaining peace. A need

to b u i ld machines that lead to a g lor ious tomorr ow w as fe l t .

Now your count ry i s waging a w ar against a very compet i t i ve enemy w ho equals your s t rength in

every aspect. I ts t im e you show your r eal potent ial to you r enem ies.

The enemy terr i tor y is l i t w i th fu l l of act iv i ty. M issiles are loaded onto thebay. Str ategic points are mar ked and t anks and m en are posi t ion ed. A sense

of urgency has spread over your land. At 0900 hours, an immediate aerial

recon of the enemy land has been cal led for. Only one Hawk is up on the

deck and ready to go. Are you brave enough to venture th ere, look in to the

si tuat ion and land hom e safely to h e lp your m achines and men w in the w ar

for your count ry? Then you got a W RIGHT FLIGHT i n you! !

I f you have a robot o r weapon des ign tha t does no t f i t w i th in the ca tegor ies se t fo r th in theabove said ru les or is in som e w ay ambiguous or b order l ine, p lease cont act t he event organizers.

Safe innovation is a lways encouraged, but surpr is ing the event staff wi th your br i l l iantexp lo ita t ion o f a loopho le m ay cause your rob ot to be d isqual i f ied be fore i t even competes.

Each event has safety inspections. It is at the judges sole d iscret ion th at you r ro bot is a l lowed tocompete. As a bui lder you are obl igated to d isclose al l operat ing pr incip les and potentia l

dangers to t he inspection staff .

Proper act ivat ion and deactivat ion of robots is cr i t ica l . Robots must only be act ivated in thearena, test ing areas, or w i th express consent of the ev ent coord inators.

All w eapons mu st h ave a safety cover on any sharp ed ges. All part ic ipants bui ld and operate robots at their own r isk. Combat robotics is inherently

dangerous. There is no amou nt o f regulat ion t hat can encom pass al l the dangers involved.

PROPULSION AN D STEERIN G

The machine must use on ly mechanica l power generated by an in terna l combust ion ( IC)engine for propuls ion. Only one IC engine should be used in the machine. Use of any other

sources such as chemicals, compressed gas, rockets etc. is not al lowed.The maximum

al lowed capaci ty of IC engine to b e used is 4 cc.

Any machine which uses DC Motors for propuls ion wi l l be disqual i f ied. However DC motorsand servos can be used for steer ing mechanisms or any other control mechanisms apartf rom pr opuls ion.

The m achine m ust h ave an on-board pow er supply to run any mechanism requ i r ing e lect r i cpower .

The electr ic vol tage anyw here in th e machine should not exceed 15V at any poin t of t ime. There sha l l be a countdown preceding the s tar t o f the race. No par t i c ipant i s a l lowed to

touch the machine dur ing the countdow n per iod.

Providing a c lutch mechanism between the engine and the wheel would prove useful , as i two uld prevent th e eng ine f rom dy ing out a t any stage o f the race.

Part ic ipants are advised to use a proper cool ing mechanism to prevent overheat ing of theengine.

Part ic ipants are advised t o use sw ay bars for bet ter con tro l and stabi l i ty . The part ic ipant s are advised t o use prop er ai r f i l ters as di r t m ight cause ser iou s prob lems to

the engine.

Readymad e wh eels are al low ed. The machine wi l l be inspected and i f found to be dangerous, the team wi l l be disqual i f ied.

This decision rests solely w i th t he jud ges and the organizers.
