     “Will robots inherit the Earth? Yes, but they will be our children”

                                                                                    -MARVIN MINSKY

The really fascinating thing about mechatronics and control is this process: you start with a “dead” piece of hardware such as a robot arm, a disk-drive, a drug delivery device, or pick your favorite example. You add some sensing and some motors around it. You then go through a process of mathematical modeling and algorithm design that is usually highly abstracted and can be very detached from reality. But then, and here’s where it gets interesting, you apply those algorithms to the hardware, and voila! Now you have a living, breathing machine with character and embedded smarts, and it’s thrilling!

About:

This year NRC comes back again with an exciting event to present your skills in the field of robotics in the form of LINE FOLLOWER. All you need is to gather your gadgets and come up with marvellous bots to compete against the best rivals. It’s time to showcase your passion towards robotics. 

Problem statement:

Line follower is an autonomous robot which follows black line in white background. The objective of this contest is to complete the course in the shortest period of time with less number of deviations from the path.

Robot Specifications:

  • The robot must fit on an A4 piece of paper.
  • There is no weight limitation. Robots must have passed inspection prior to competing.
  • Robots have to have an easily reachable emergency stop button which interrupts the power supply of the actuators.
  • On demand of the jury or in imminent danger, a team member has to stop the robot immediately.
  • Robots have to operate autonomously and should not be remote-controlled.
  • All systems (like sensors, power supply, data-processing and control-systems) have to completely reside on the robot.
  • No limitation as such in the motors.
  • The wheels used must be non-destructive to the surface.
  • Energy sources like springs, compressed-air, batteries, etc. are permitted.
  • Combustion engines are not allowed because of noise and exhaust gas.

 

 

 

Course Specifications:

§The line following course shall traverse a white paper rectangle (approx. 3mx1m). The line shall be black electrical tape while the base is white traversing the arena from end to end.

§The width of the black line is 3 plus or minus .5 cm.

§There shall be a starting area at the beginning of the course and an exit area at the end. The line course starts inside the starting area and ends inside the exit area.

§There shall be crossovers (e.g. places where the line crosses itself)

§Switchbacks and hairpins are possible, but the adjacent sections of the line shall be no closer together than 15cm when measured from the center of each line.

§The line course may have one or more sharp right-angle and some acute and obtuse angles.

§The closest approach of the line course to the edges of the arena shall be no less than 15cm, measured from the center of the line.

§The decisions of all officials regarding these rules and the conduct of the event shall be final.

 Rules and regulations:

  • Team may have a maximum of 5 members.
  • The robot has to be developed and designed by the team itself. The usage of commercially complete robotic-systems which are sold ready for the purpose of the competition is not allowed. At least the software-development should show significant personal effort.
  • The time of any run is measured from the time the robot crosses the starting line until the time it crosses the finish line. A robot is deemed to have crossed the line when the forward most wheel, track, or leg of the robot contacts or crosses over the line.
  • Timekeeping: Time shall be measured by an electronic gate system or by a judge with a stopwatch, based on the availability of equipment. In either case the recorded time shall be final.
  • A robot that wanders off of the arena surface will be disqualified.
  • A robot shall be deemed to have left the arena when any wheel, leg, or track has moved completely off the arena surface.
  • Losing the Line: any robot that loses the line course must reacquire the line at the point where it was lost, or at any earlier (e.g. already traversed) point.
  • Robots have to stay on the ground. Thus they may not fly or jump. All kinds of weapons (saws, lasers, electroshocks, hammer) are strictly forbidden.
  • Claims because of changing lighting conditions in the room or flash lights of photographers won't be accepted. Participants have to face these "disturbances".
  • Equipment which harms or disturbs another robot (e.g. jammer, light flash, interfering ultrasonic or infrared transmitter) are forbidden. Disturbances or assistance caused by intervention of humans during a competition are forbidden as well.

 

Judging Criteria:

 

  • A maximum time of 5 minutes is allowed for a robot to complete the course. A robot that cannot complete the course in the allotted time shall be disqualified.
  • The track is divided into checkpoints at various locations. A team will be awarded 20 points on crossing a checkpoint.
  • A maximum of 3 corrections are allowed. For every next correction the team will be deducted with 5 points.
  • On completion of the whole track in given time, the team is given 40 points.
  • For teams which complete within 5 minutes extra points will be given
  • Extra 40 points will be awarded for a bot built with a self-made design rather than a commercially complete robotic-system which are sold ready for the purpose of the competition is not allowed.
  • The organizers reserve the right to change any or all of the rules as they deem fit.
  • Violation of any of the rules will lead to disqualification. Event Managers decision shall be treated as final and binding on all.
  • The teams may be asked questions on the design of the circuit and other details on the implementation.

ROBO WARS
  “ You just can't differentiate between a robot and the very best of humans”                                                                                                                                           
ABOUT:
               Have you ever wondered, what will happen when the formidable robots will clash? It will be a battle every human aspires to watch. An event that you cannot miss and a memory which you cannot erase. It’s not often when you watch machines destroying each other for entertainment. Gears will grind and sparks will fly, much more is at stake as the robots battle it out in a bid to be the best. These messengers of destruction will duel for honour and denomination with pneumatic pincers, weedy axes, chain saw tails, hurling maces, flamethrowers and loads more. A War that will bring your hearts in your mouth.

Be there to witness the impossible

Be there to get goose bumped.
Be there at ROBOWARS….!!!!

PROBLEM STATEMENT:
                 
                  The objective is to make a manually controlled bot capable of immobilizing ,fighting aggressively with control and ultimately knocking out of other bot.


TEAM DETAILS:

 Each team must consist a maximum of 5 members .2 members of  the team are allowed to handle the bot during the match.

BOT SPECIFICATIONS:

*Dimensions:

 *The machine should fit in a box of dimension 60cm x 60cm x 60cm (l x b x h) during the starting of the match. The external device (remote) used to control the machine is not included in the size constraint. (However there is no limitation on dimension once the match starts).
 

*The machine should not exceed 50 kg of weight including power supply. 10% allowance in weight shall be given to the bots with off board power supply.

*MOBILITY:
       
  .The bots should use only wheels for moving.
  .Jumping, Flying, Hopping of bots is not allowed.

*ROBOT CONTROL:

. The machine can be controlled wirelessly or with wires. Off board power supplies are allowed.

  • If the machine is wired then the wire should remain slack under all circumstances during the competition. All the wires coming out of the machine should be stacked as a single unit. Teams are suggested to use only rated wires. Loose connections may lead to direct disqualification even before the event.
  • If the machine is controlled wirelessly, the machine must at least have a four frequency 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.
  • The robots are not allowed to cut the opponents control wire.
  • Violation of this rule will lead to disqualification

 

*POWER SYSTEM: 

The bot must be powered by electrical means only. Other means of powering the system like use of IC engines, Pneumatics in any form is not allowed.

The electric voltage between any two points in a machine should not exceed 36V DC at any point of time. The same is the case with AC as well.
 

*BATTERY:

On board Batteries must be sealed, immobilized-electrolyte types (such as gel cells, lithium, NiCad, NiMH, or dry cells).
 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.

*USAGE OF WEAPONS:

Robots 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, 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.

  *JUDGEMENT CRITERIA:

  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.
  • In case both the robots remain mobile after the end of the round then the winner will be decided subjectively.

Points will be allocated to the bots as per following criteria:


1) 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.


2) Control - Control means a robot is able to attack an opponent at its weakest point, use it's weapons in the most effective way, and minimize the damage caused by the opponent or its weapons.


3) Damage - Through deliberate action, a robot either directly or indirectly reduces the functionality, effectiveness or defensibility of an opponent. Damage is not considered relevant if a robot inadvertently harms itself.


4) Pinning - A bot will be considered pinned it is held by the opponent such that it is unable to move for at least 10 seconds.

  • The time period of each fight is 2 min.
  • No repairs are allowed to the bot during the match. A team can stop the match only if it quits i.e. the opponent team will be declared victorious.
  • Violation of any of the rules will lead to disqualification.
  • Judges decision shall be treated as final and binding on all.
  • A team may consist of maximum of 5 people all from the same college, but only two people are allowed to control the bot during a match.

  

ARENA SPECIFICATIONS:

  • Arena will be a square area of dimension 10x10 ft.
  • The arena will be made of plywood, and will be at a height of 0.5 ft above the ground.
  • The organizers reserve the right to change any or all of the rules as they deem fit.
  • Violation of any of the rules will lead to disqualification.
  • Judges decision shall be treated as final and binding on all.

“There are an endless number of things to discover about robotics. A lot of it is just too fantastic for people to believe.”
