Relive your childhood by playing 7 stones, but with a spark of science. A contest very similar to 7 stones where bots do all the work. Involving two teams, 7 stones requires both teams to build a stack while attacking the enemy’s stack at the same time.
With additions like ramps and beacons, use your bots and strategic skills to dominate the arena by building your stack and defending it from your enemy or by going full offensive and wrecking your enemy’s stack. Will your bots make the stack in time? Or will they be razed to the ground by your enemy? Bring in your ingenious ideas and designs and let’s find out!

Game Structure:
Each Game is a one on one match involving Team Red and Team Blue.
Each team has a Stack bot and an Attack bot.
The arena is divided into two zones, one for each team.
Each zone is further divided into two subzones – Stacking zone and Shooting Zone.
Each stack zone has 7 boxes. One of them is slightly larger and has a provision to place balls.
The stack zone has a circle within which the boxes have to be piled up.
The attack zone has a predefined loading spot containing the shooting balls.
There is a ramp in the center of the arena and is split into two parts extending towards each team's stacking zone. The ramp is divided into three levels – top, middle and bottom. The balls are placed in the bottom level.
Each game is divided into two segments - Autonomous Period and Manual Period.
Autonomous Period: Time Duration: 30 seconds
Stack bot/Attack bot will be activated and should be programmed to:
Climb up the ramp.
Activate the Trigger to release the balls onto the arena floor. There will be two release boxes, one for each team. A latch will be provided and the robot should hit the latch to release the balls. This should be done by the any bot. (20 points)
If none of the stack bots/attack bots are able to release the colored balls onto the arena floor, it will be done by the event managers manually at the end of the Autonomous Period.
There will be 30 seconds of transition time for
Releasing the colored balls manually
Placing the Stack bots/Attack bot on the arena floor at the respective start positions.
Manual Period: Time Duration: 8 minutes
The initial 5 minutes is the Stack Period and remaining 3 minutes is the Attack Period.
During the Stack period, the Stack bot is expected to do the following tasks:
Placing the balls in the larger box. (10 points per ball)
Having the larger box as the base, stacking the remaining six boxes on top of each other. (10 points per box. NOTE: Final state of piled up boxes are taken into account)
During the attack period
The Attack bot has to load the shooting balls from the loading area.
The Attack bot has to shoot and disturb the piled up boxes of the opponent team. After the first attack, the Attack bot can either get on to their respective ramp (with fewer points) or keep attacking the opponent stacks. (NOTE: If the attack bot hits the opponent bots, 10 points will be deducted as penalty for improper attack.)
The Stack bot can still try stacking the box.
At the end of the game if the Attack bot climbs to the ramp and stays, the following points are awarded:
Middle level – 20 points
Bottom level – 10 points
The ramp will be like this:
The dimensions of the ramp are as follows:
Inclinations are 10 and 15 degrees.
All the flat surfaces are 20 inch long and width of the ramp is 25 inch.
The shooting balls will be plastic balls of 6cm diameter and stacking balls will be spongue balls of 10cm diameter.
Also, there will be an interview by TCS Jury which will be taken into consideration while announcing the winners.
The winner of the game will be decided on the basis of the total number of points earned.
Each team can use only two robots (one Attack bot and one Stack bot).
The robot should fit within a 20 inch cube.
The robot must be designed and constructed by the students themselves.
Robot can be wired or wireless. In case of a wired bot, the length of the cable should be at most 4 meters and in case of a wirelessly controlled bot, the communication of the bot should not interfere with the opponent’s bot (e.g. In case of a RF controlled bot, make sure transmission is possible with two different frequencies).
Hydraulics or chemical energy should not be used for any mechanism, however pneumatics can be used and in that case the pressure should be less than 6 bars.
If a team is using Li-Po or Li-ion batteries, it is the team’s responsibility to make sure there is no risk involved in its usage.
The bot or the operator cannot modify the arena in any case.
The Maximum number of players per team is 6.
Intercollege teams are not allowed.
Only 2 players are allowed to enter the arena.
