Technical Problems on Robotics

Problem 1 :

The objective of this contest is to complete the course in the shortest period of time while accurately
tracking the course line from start to finish. In this problem the ROBOT SHOULD BE SELF-CONTROLLED AND SELF-PROPELLED WITHOUT ANY TETHER.

You need to design a robot that moves as quickly as possible without losing the line. If it loses the line, it then needs to be able to get back to the point at which it left the line or from a prior point on the course. You may need to slow your robot down so that you electronics have enough time to react. If you are programming your robot, try to push the speed limit. If you go off the line, put in a function for finding the line again.
After positioning and starting the robot, no remote control, power, positioning, or other help can be provided. The robot must care for itself until the round ends. The given path is 4 cm wide, and the details regarding shape would be given at the time of EVENT only. The Path which is given to traverse is of Black Colour and rest around will be White.
1. Size and Weight Limits: dimensional and weight as described in Manual Part.
2. Course Time: time is measured from the time the robot crosses the starting line until the time it crosses the finish line.
3. Time Limit: Maximum Limit will be updated soon.
4. Autonomous Control: once a robot has crossed the starting line it must remain fully autonomous, or it will be disqualified.
5. Arena Edges: 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.
6. 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.
7. Second Attempt: any robot that loses the line course and fails to reacquire it will be allowed a single reattempt. The robot must start the course again from the beginning, and if it loses the line course on its second attempt it will be disqualified.
8. Course Specifications: There is 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 (This would be entrance
for Manual Area).
The start and end points of the line course will be clearly marked via a transverse line no more than 2mm
wide.
Characteristics of the line course:
1. There are crossovers (e.g. places where the line crosses itself)so while crossing the arena both must not lose it’s original path.
2. The line course would have 1 or more sharp right-angle, and have turns having obtuse angle.
3. The closest approach of the line course to the edges of the arena is not less than 15cm, measured from the center of the line.

Problem 2:

The sumo's basic rule is that the one who first makes his opponent step outside of the ring (Dohyou ) or makes him touch the ground with any part of his body wins. This is what you have to do during second part of the problem.
Two (self-driven/wired/wireless) robots are placed in a ring. The robots must try to avoid falling out or avoid being pushed out by the opponent robot. The first robot that touches outside of the ring loses the round.
The first robot to win two rounds, wins the match. Different robots compete one-on-one against each other
throughout the contest. The robot that wins the most matches wins the contest.
WEIGHT:
The Robot may be Autonomous or manual. As per the mass is concerned, Sumo robots may have a mass of 3 kilograms (6.6 pounds) or less. As long as all other requirements are met, Sumo robots can be made out of any material. They can use any type or size of electric motor or electric-powered locomotion. They can contain any kind of processor, electronics, sensors, or batteries desired.
DIMENSIONS:
At the start of each round, Sumo robots must not exceed a specified width and depth. Sumo Robots can be 25 centimeters or less in length and width and 25 centimeters or less in depth. Also, as soon as movement is allowed in a round, the robot may then twist, fall, or expand without size limits.
HARMLESSNESS:
At all times, robot behavior must be non-offensive, non-destructive, and non-harmful to humans, robots, and the facilities. During inspection (and at any time during the event), the judges may require safety changes or other modifications to meet the harmlessness requirement. Harmful robots are either not allowed to compete at all or are later disqualified if potential harmful issues are proven or revealed in battle.
Failures due to exposed wires or unsecured or flimsy parts shall be the responsibility of the robot with such
Weaknesses.
At all times, Sumo Robots must not:
  • Emit smoke or fire
  • Leak, stain, or soil
  • Disperse powder, grit, or grime
  •  Spray, throw, or use projectiles
  • Jam, shock, or electromagnetically interfere
  • Snare, entangle, or employ nets/rope
  • Scratch, gouge, or scrape
POSITIONING:
The contestant may place his or her robot in any position, angle, or location on the ring except that no portion of the robot may cross the extended starting line nearest the contestant. The robot must fit within the required starting dimensions (25 cm x 25 cm). By the way, after the initial placement of the first robot, it isn't permissible to alter its starting position. Even though this may be desired in reaction to the placement of the second robot! So the order will be decided by Toss-Up.

At the referee's discretion, the referee may choose to restart a round if:
  • Three minutes have expired
  • No progress has been made in some period of time
  • The robots fail to touch each other for some period of time(in case of Autonomous System Only).
  • The robots are hopelessly entangled or otherwise deadlocked
  • Both robots fail to start or both contestants signal stoppage.
 At the referee's discretion, the referee may choose to end a round and choose the round winner if:
  • Smoke, fire, damage, or any other violation has occurred
  • No progress is likely to be made even if the round is restarted
OUT:
A robot loses a round when any portion (including touch sensors, whiskers, scoops, or skirts) of the robot touches outside of the ring. It doesn't matter if the robot falls out on its own or is pushed out. The first robot touching outside of the ring loses, even if the second robot subsequently touches outside of the ring. If the referee determines that both robots touched outside of the ring at the same time, the round is nullified and started over.

If any piece of the robot, more than 5 grams if detached, touches outside of the ring, the robot is considered out. For example, if a nut drops off a robot within the ring, the robot doesn't immediately lose. However, if the nut is then pushed out or rolls out, the robot loses.
If a robot lands outside the ring atop a whisker, scoop or any portion of the opponent robot, the opponent robot is out. This is consistent with the policy that the robot that touches outside first is out, even if the second robot subsequently touches outside the ring.

NOT OUT:
Starting to fall or breaking the plane of the ring isn't considered out. Some portion of the robot must actually touch outside the ring.

DURATION OF MATCH :
The first robot to win two rounds, wins the match. This means there can be as few as two very quick rounds to win a match. These are three-minute rounds . Each robot must have won a round to force the third-round tiebreaker. This Tie-Breaker will be decided during event by judges only. Of course, a match may also end if a contestant or robot is disqualified or otherwise unable to complete.
NOTE:
During match any participant can take 2 minutes time out, if he gets any trouble in BOT. He can utilize it in either in Some Technical Fault, or during Robot Failure. The maximum number of TIME OUT IS 3.
