Dimensions and Fabrications
- The machine should fit in a box of dimension 750 mm x 750 mm x 1000 mm (lxbxh) at any given point during the match. The external device used to control the machine or any external tank is not included in the size constraint.
- The machine should not exceed 60 kg of weight including the weight of pneumatic source/tank. All pneumatic tanks/source and batteries should be onboard. Weight of remote controller will not be counted.
MobilityAll robots must have easily visible and controlled mobility in order to compete. Methods of mobility include:
- Rolling (wheels, tracks or the whole robot).
- Non-wheeled robots having no rolling elements in contact with the floor and no continuous rolling or cam operated motion in contact with the floor, either directly or via a linkage. Motion is "continuous" if continuous operation of the drive motor(s) produces continuous motion of the robot. Linear-actuated legs and novel non-wheeled drive systems come under this category.
- Jumping and hopping is not allowed.
- Flying (using airfoil, helium balloons, ornithopters, etc.) is not allowed.
Robot Control Requirements
- The machine can be controlled through wired or wireless remote. Power supply should be onboard only. Refer below for further details on battery and power.
- The machines using wireless remote must at least have a four frequency remote control circuit or two dual control circuits which may be interchanged before the start of the race to avoid frequency interference with other teams. The case of any interference in the wireless systems will not be considered for rematch or results.
- Remote control systems from toys might be used. Remote control systems available in the market may also be used.
- Non standard or self made remote control systems must first be approved by the organizers.
- The voltage difference/voltage input in the remote control should not exceed 9V at any point of time and during the entire length of the competition. But if there is no wired connection between robot and the remote controller then potential difference can exceed the given limit of 9V.
Battery and Power
- The machine can be powered electrically only. Use of an IC engine in any form is not allowed. On board Batteries must be sealed, immobilized-electrolyte types (such as gel cells, lithium, NiCad, NiMH, or dry cells).
- The electric voltage between 2 points anywhere in the machine should not be more than 36 V DC at any point of time.
- All efforts must be made to protect battery terminals from a direct short and causing a battery fire, failure to do so will cause direct disqualification.
- Use of damaged, non-leak proof batteries may lead to disqualification.
- Special care should be taken to protect the on-board batteries.
- Change of battery will not be allowed during the match.
- Only bots with onboard batteries are allowed.
- Robot can use pressurized non-inflammable gases to actuate pneumatic devices. Maximum allowed outlet nozzle pressure is 8 bar. The storage tank and pressure regulators used by teams need to be certified and teams using pneumatics are required to produce the Safety and Security letters at the Registration Desk at the venue. Failing to do so will lead to direct disqualification.
- Participants must be able to indicate the used pressure with integrated or temporarily fitted pressure gauge. Also there should be provision to check the cylinder pressure on the bot.
- The maximum pressure in cylinder should not exceed the rated pressure at any point of time.
- You must have a safe way of refilling the system and determining the on board pressure.
- All pneumatic components on board a robot must be securely mounted. Care must be taken while mounting the pressure vessel and armour to ensure that if ruptured it will not escape the robot. The terms 'pressure vessel, bottle, and source tank' are used interchangeably.
- Entire pneumatic setup should be onboard, no external input (from outside the arena) could be given to the robot for functioning of its pneumatic system.
- Robot can use non-inflammable liquid to actuate hydraulic devices e.g. cylinders.
- All hydraulic components on-board a robot must be securely mounted. Special care must be taken while mounting pump, accumulator and armour to ensure that if ruptured direct fluid streams will not escape the robot.
- All hydraulic liquids are required to be non corrosive and your device should be leak proof. Maximum allowed pressure is 8 bars.
- Participant must be able to indicate the used pressure with integrated or temporarily fitted pressure gauge.
- Entire hydraulic setup should be onboard, no external input (from outside the arena) could be given to the robot for functioning of its hydraulic system.
Weapons SystemsRobots can have any kind of magnetic weapons, cutters, flippers, saws, lifting devices, spinning hammers etc. as weapons with following exceptions and limitations:
- Liquid projectiles.
- Any kind of inflammable liquid.
- Flame-based weapons.
- Any kind of explosive or intentionally ignited solid or potentially ignitable solid.
- Nets, tape, glue, or any other entanglement device.
- High power magnets or electromagnets.
- Radio jamming, tazers, tesla coils, or any other high-voltage device.
- Tethered or un-tethered projectiles.
- Spinning weapons which do not come in contact with the arena at any point of time are allowed. In no case should the arena be damaged by any bot. The competition will be played on a knock-out basis. There can be some hazards in the arena (subject to change, will be notified as soon as decided)
Video and Abstract SubmissionParticipants have to submit a portfolio of their machine, consisting of a written abstract and a video of the working model before the competition. This portfolio will be used to seed teams for the competition. Only the shortlisted teams will be eligible to participate in 'Robowars: Fatal Combat' at Techfest 2013. The teams can do an online submission, mailing us the soft copy of abstract (PDF format only) and a youtube video link of your robot (keeping the privacy option unlisted) at email@example.com with subject 'Robowars: Fatal Combat Team ID'. Offline submission won't be entertained. Last date for portfolio submission is 1st December 2012, 11:59 AM for the teams seeking accommodation and 7th December 2012, 11:59 PM for teams which are not seeking accomodation.
AbstractThe written abstract should be prepared on the following lines:
- The weapon systems and power supply method should be explained in detail, along with proper diagrams. Picture(s) showing these should be attached.
- Description of any unusual advantageous mechanism used.
- The specifications of all the components used, including motors, suspension springs, remote controller, wires, battery etc. have to be mentioned.
- You can email the portfolio minus the video and send the video later. This will make sure at least the abstract part of your portfolio reaches us before the deadline.
- An email will be sent to the team leader confirming the receipt of the entry. Each team is allowed to make online submission only by email. In case of multiple submissions, only the first submission will be used for judging purposes.
- Techfest 2013 is not responsible for any delays in terms of receiving portfolio, so participants are encouraged to mail their entries well in advance to ensure receipt before the last date.
- The video should be at least 1 minute unedited clip showing the machine performance to the fullest. All destructive mechanism(s) being used must be shown working.
- It is not necessary to explain the mechanisms in the video. All portfolios will be used strictly for the seeding purposes. The elimination procedure will be objective and the evaluation of every participant will be published on the website. Techfest assures total privacy of the matter submitted to us. The portfolio of your machine will be helpful in future as an evidence of your hard-work along with determining your position for the competition. Hence, please pay adequate attention to it.
Criteria for Victory
- A robot is declared victorious if its opponent is immobilized.
- A robot will be declared immobile if it cannot display linear motion of at least one inch in a timed period of 30 seconds. A bot with one side of its drive train disabled will not be counted out if it can demonstrate some degree of controlled movement. This rule will also apply to any robot that becomes trapped by any part of the arena or arena hazards, including the pit.
- In case both the robots remain mobile after the end of the round then the winner will be decided subjectively.
- A robot that is deemed unsafe by the judges after the match has begun will be disqualified and therefore declared the loser. The match will be immediately halted and the opponent will be awarded a win.
- If a robot is thrown out of the arena the match will stop immediately, and the robot still inside the arena will automatically be declared as the winner.
- Robots can not win by pinning or lifting their opponents. Organizers will allow pinning or lifting for a maximum of 20 seconds per pin/lift then the robots will be instructed the attacker to release. If, after being instructed to do so, the attacker is able to release but does not, their robot may be disqualified. If two or more robots become entangled or a crushing or gripping weapon is employed and becomes trapped within another robot, then the competitors should make the timekeeper aware, the fight should be stopped and the robots separated by the safest means.
- Points will be given on the basis of aggression, damage, control and strategy Aggression - Aggression is judged by the frequency, severity, boldness and effectiveness of attacks deliberately initiated by the robot against its opponent. If a robot appears to have accidentally attacked an opponent, that act will not be considered Aggression. Control - Control means a robot is able to attack an opponent at its weakest point, use its weapons in the most effective way, avoid Arena Hazards, and minimize the damage caused by the opponent or its weapons. Damage - Through deliberate action, a robot either directly, or indirectly using the Arena Hazards, reduces the functionality, effectiveness or defensibility of an opponent. Damage is not considered relevant if a robot inadvertently harms itself. Also, if a pressure vessel or a rapidly spinning device on a robot fragments, any damage to the opponent will not be considered "deliberate". Strategy - The robot exhibits a combat plan that exploits the robot's strengths against the weaknesses of its opponent. Strategy is also defined as a robot exhibiting a deliberate defense plan that guards its weaknesses against the strengths of the opponent. Strategy can also involve using the Arena Hazards to gain an advantage.
Safety RulesCompliance with all event rules is mandatory. It is expected that competitors stay within the rules and procedures of their own accord and do not require constant policing
- Special care should be taken to protect the on-board batteries and pneumatics, robot without proper protection will not be allowed to compete.
- If you have a robot or weapon design that does not fit within the categories set forth in these rules or is in some way ambiguous or borderline, please contact the event organizers. Safe innovation is always encouraged, but surprising the organizers with your brilliant exploitation of a loophole may cause your robot to be disqualified before it even competes.
- Each event has safety inspections. It is at their sole discretion that your robot is allowed to compete. As a builder you are obligated to disclose all operating principles and potential dangers to the inspection staff.
- Proper activation and deactivation of robots is critical. Robots must only be activated in the arena, testing areas, or with expressed consent of the event coordinators.
- All weapons must have a safety cover on any sharp edges.
- All participants build and operate robots at their own risk. Combat robotics is inherently dangerous. There is no amount of regulation that can encompass all the dangers involved. Please take care to not hurt yourself or others when building, testing and competing.
- Any kind of activity (repairing, battery handling, pneumatics systems etc.) which may cause damage to the surroundings during the stay of the teams in the competition area should not be carried out without the consent of organizers. Not following this rule may result in disqualification.
- All the resources provided at the time of competition from the organizers should be strictly used only after the consent of the organizers.
- Once the robots have entered into the arena, no team members can enter into the arena at any point of time. In case if fight has to be halted in between and some changes have to be done in the arena or condition of the robot(s), it will be done by organizers only.
Team SpecificationA team may consist of a maximum of 6 participants. Participants can be from the same or different educational institutes. Team Name: Every team must have a name which must be unique. Techfest reserves the right to reject entries from any Team whose name it deems inappropriate, offensive or conflicting. Organizers must be notified during if a Team's name has been changed. Team Representative: Each team must specify their Team Representative (Leader) at the time of registration on the website. All important communications between Techfest and the registered teams will be done through Team Representative. The Team Representatives must submit valid contact details (phone no., email ID etc.) at the time of registration. NOTE: During any kind of conversation, registration, communication, mails or submissions the team must identify themselves by their Team ID only provided at the time of registration and not your team name. Please do not use your team name as your identification in any kind of communication with us. Follow this rule very strictly.
Safety LetterTeams using pneumatics or hydraulics will have to send a safety letter signed be any faculty in- charge/ Lab in- charge or a testing lab/company dealing in this field, on the format given on the introduction page. Soft copy of the letter can be attached with the portfolio separately. Teams should also bring original copy of this certificate during Techfest if get selected.
Certificate PolicyCertificate of Excellence will be given to all the winners. Certificates of Participation will be given to all the teams who qualify first round of the competition. The teams which get disqualified due to disobeying any of the competition rules will not be considered for the certificate. * Prizes worth INR 20,000 to be won for best designs, engineering, weapon and other subjective criterion (subject to judges discretion)
Event specific Terminologies
- Disabled – A robot is not functioning correctly due to either an internal malfunction, or contact with the opposing robot or Arena Hazard.
- Disqualification – A Robot is no longer permitted to compete in the current Robowars Tournament.
- Immobilized – In Judge's opinion, a robot is not Responsive for a specified period of time.
- KnockOut – Occurs when the attack or deliberate actions of one robot causes its opponent to become immobilized.
- Lifting – Occurs when one robot controls an opponent's translational motion by lifting the drive mechanism of the opponent off of the Arena floor.
- No Contact – Occurs when neither robot makes contact with each other, or with the Arena Hazards for a specified period of time.
- Pinning – Occurs when one robot, through sheer force, holds an opponent stationary in order to immobilize it.
- Radio Interference – Refers to the situation where at least one robot becomes non-Responsive or non controllable due to the effect of the other robot's remote-control signal.
- Non-Responsive – In a Referee's opinion, the robot cannot display some kind of controlled translational movement along the Arena floor.
- Restart – Occurs after a Fault or a Timeout has been declared and the competing robots are ready to continue.
- Stuck – A robot is hung-up on a part of the Arena, an Arena Hazard or an opponent, such that it is effectively non-responsive.
- Tap-Out – Occurs when a robot's Operators decide that they no longer want to continue the Match, and concede the win to the opposing Team.
- Technical KnockOut – Occurs when a robot wins due to immobilization of its opponent even though, in the Judges' opinion, no action of the winning robot caused the opponent's immobilization.
- Timeout – A temporary halting of a Match. Timeouts are usually called to seperate robots, but can be called for other reasons.
- Proper planning is necessary for making a properly functioning bot. So, plan everything well before making a robot. Planning includes deciding the ratings of parts like motor, wires, battery to be used. For calculating the specifications of various parts required, visit http://www.societyofrobots.com/calculator.shtml. Any wrong specifications would lead to a failure and also disqualification from the competition.
- All pneumatic systems should have a flow valve for control of flow of air. It would help you adjust the flow rate and hence, the output power to your choice.
- All terminals should be properly insulated to prevent any chances of short-circuit.
- For safety purpose, there should be a fail-safe mechanism to deal with all kinds of failure.
