3 Robot Specifications

3.1 Dimensions and Fabrication

 There are 3 type of robots(bots):

1. Grid solving robot
2. Maze solving robot
3. Manual robot

3.1.1 Grid solving autonomous robot 

1. Maximum 2 autonomous grid solving robots per team are allowed. A team may enter with only 1 autonomous robot.
2. The top view of each autonomous robot must fit within a square of dimensions 200mm x 200mm (l x b).
3. Robot must be started individually by only 1 onboard switch. However, a team may have a separate onboard switch for restart.(refer pt.10 of Rules)
4. The autonomous robot(s) must be stable and must stand on its own at the beginning of the run when put in the starting point. robots not fulfilling this criterion will be disqualified.
5. During the run, the autonomous robot can expand itself provided it does not damage the arena in anyway. However, it is not allowed to leave anything behind or make any marks while traversing the grid. All robots found damaging the arena will be immediately disqualified. The final decision is at the discretion of the organisers.
6. The autonomous robot should not separate or split into two or more units. All robots/units which are touching each other or are in the starting point will be considered as one robot.
7. The methods of collection and delivery of the blocks are at the discretion of the builder. However, the teams damaging the blocks will be disqualified. The teams are allowed to use ready-made wireless modules/ready-made micro-controller boards/ready-made sensor kits.

3.1.2 Maze solving robot

1. 1.  Only one maze solving autonomous robot per team is allowed.
2. The top view of the bot must fit within a square of dimensions 200mm x 200mm (l x b).
3. This robot must strictly work on the principle of line following.
4. The robot must be stable and must stand on its own at the beginning of the race when put in the starting point. robots not fulfilling this criterion will be disqualified.
5. During the run, the robot can expand itself provided it does not damage the arena in anyway. However, it is not allowed to leave anything behind or make any marks while traversing the maze. All robots found damaging the arena will be immediately disqualified. The final decision is at the discretion of the organisers.
6. The autonomous robot should not separate or split into two or more units. All robots/units
   which are touching each other or are in the start zone will be considered as one robot.
7. The methods of collection and delivery of the blocks are at the discretion of the builder.  However the teams damaging the blocks will be disqualified. The teams are allowed to use ready-made wireless modules/ready-made micro-controller boards/ready-made sensor kits.

3.1.3 Manual robot (optional)

1.  Only 1 manual robot per team is allowed.
2.  During the start of the run the manual robot must fit within a cube of dimension 300 mm x 300 mm x 350mm (l x b x h).
3.  Bot must be started individually by only 1 switch.
4.  At the start of the run and during restarts the manual robot can be placed anywhere on the uneven terrain.
5.  The robot must be stable and must stand on its own at the beginning of the run when put in the starting point. robots not fulfilling this criterion will be disqualified. The robot shouldnot split up into 2 or more parts during the run.
6. The external wired remote control used to control the bot is not included in this size constraint.
7. The onboard power supply on the bot must fit within this size constraint.
8. Manual bot cannot be constructed using readymade Lego kits or any readymade mechanism. But you can make use of readymade gear assemblies. Violating this clause will lead to the disqualification of the team.
9. The manual robot cannot deposit/collect any blocks/bot outside the central part, i.e. at any point of time, the top projection of the manual bot must be in the central zone.

3.2 Power Supply and Propulsion  

1. The robots have to use an on-board power supply. No external power supply will be allowed.
2. Each team shall bring its own power supply for all its robots.
3. The potential difference between any two points on any of the bots must not exceed 24V DC.
4. In case the robot is using a non-electric power supply, kindly get it approved from the organisers beforehand via email. Organisers are not responsible for inconvenience if approval is not sought. 
5. The method of propulsion is at the discretion of the builder, provided that the power source is non-polluting.

3.3 Controls of the Robot

1. Both the grid solving autonomous bot and the maze solving autonomous bot should not receive any input from outside the arena. They are however encouraged to communicate wirelessly with the other autonomous bot in the arena for cooperative benefits. 
2. The manual bot should not receive any wireless input from outside the arena. It can be controlled using a wired remote control.
3. No wireless communication between autonomous bot and manual bot is allowed. The team is responsible for proving this to the organisers.
