TECHFEST 2023-24

COZMO CLENCH

TASK

● Teams have to build a manually controlled bot that can do simple tasks of gripping objects
and putting them in target zones so that it can complete the route by overcoming the
hurdles in its path.

BOT SPECIFICATIONS

● The dimensions of the bot should be less than or equal to 300 mm X 200mm X 300mm
(lxbxh) failing which the team will be disqualified from the competition (this excludes the
dimension of the gripper but includes tires). The bot can, however, extend its dimension once
the run starts. An error of (±5%) is permitted.
● The bot must be controlled manually.
● Teams can use both wired as well as wireless control mechanisms. In the case of wired
bots, the length of the wire should be a minimum of 2 metres so that the wire remains slack
at any instant of time. If the participants use a wireless mechanism they have to use either a
dual-frequency remote, Bluetooth, or Wifi.
● The dimensions of the remote are not included in the size constraint of the bot.
● The Bot must have an onboard power supply in any case.
● Participants are not supposed to use any readymade Lego components or readymade
gripping mechanism. However, the participants are allowed to use ready-made gear
assemblies.
● The mechanism used should be such that only one person will control the bot.
● Failing to meet any of the above specifications will lead to immediate disqualification.

POWER SUPPLY

● The participants should use an onboard electric or non-electric power supply i.e. the power
source should be on the bot itself. The power source must be non-polluting and must satisfy
the safety constraints determined by the organizers. In the case of the non-electric power
supply, the participants must get it approved by the organizers beforehand via email.
Organizers are not responsible for the inconvenience if approval is not sought.
● In the case of an electric power supply, the voltage between any two points should be less
than or equal to 24V DC at all times during the run.
● AC power supply will not be provided and cannot be used in the competition.
 ARENA

● The outer dimensions of the arena are 2500mm X 2500mm (lxb).

It consists of the following:
❖ Five thermocol blocks out of which four (block 1,2,3 & 4) of dimensions 120mm X
120mm X 120mm (lxbxh) and one block (block 5) of diameter 120mm and height
120mm.
❖ 4 Circular Pipes of dimension 400mm length & 10mm Radius.
❖ 3 Semi-Circular Pipes of dimension 400mm length & 20mm Radius.
❖ “Deposit Zone 1” of dimensions 150mm X 150mm (lxb) (shown in green light colour).
❖ “Deposit Zone 2”, “Deposit Zone 3” of dimensions 200mm X 130mm X 120mm (lxbxh)
(shown in light green).
❖ “Deposit Zone 4” of dimensions 120mm X 120mm X 120mm (lxbxh) (shown in light
green colour).
❖ “Deposit Zone 5” of diameter 150mm (shown in light green colour).
❖ Ramp assembly has an inclination of 20 degrees.
❖ One Half Ramp assembly with a declination of ~30 degrees.
❖ One Half Ramp assembly of inclination 20 degrees before the sand pit.
❖ A Box of marbles of dimensions 400mm X 400mm X 25mm (lxbxh) with the extension
of 100mm on one side of length and breadth each.
❖ The zig-zag path has a height of 50mm each and incline of 45 degrees.
❖ The strip bridge (in Fig. 6) spans over a dimension of 540mm X 400mm X 200mm.
❖ Each strip is of width 80mm and the gap between them is 80mm.
❖ The bridge (in Fig. 6) spans over a dimension of 550mm X 400mm X 100mm.
❖ An individual wood piece (in bridge) is of dimension 400mm X 25mm with gaps of
dimension 400mm X 10mm.
❖ 3 stairs each of width 50mm and height 45mm.
❖ Sand Box of dimensions 400mm X 400mm X 25mm (lxbxh).
❖ “Checkpoints” A, B, C & E of Dimensions 400mm X 40mm are shown in Green Colour.
❖ “Checkpoint D” of dimensions 400mm X 30mm is shown in Green Color.
❖ “START” and “FINISH” of dimensions 400mm x100mm are shown in Green Colour.

 GAMEPLAY

● The bot must start from the ‘START’ mark.

● The bot has to arrive at Checkpoint A by manoeuvring through the obstacles and Marble Pit
along the track while carrying Block 1.
● The bot has to place Block 1 in Deposit Zone 1 after crossing the semi-circular pipes.
● The bot arrives at Checkpoint B after placing the Block 1 in Deposit Zone 1.
● Now, the bot has to pick Block 2 and place it at Deposit Zone 2. If Block 2 gets dropped on
the ramp, the bot will have to go again to Checkpoint B.
● Once Block 2 is placed in Deposit Zone 2, the bot has to go down the ramp and pick Block 3
to put it in Deposit Zone 3. If Block 3 gets dropped on the ramp, bot will have to go again to
the top of the ramp and descend.
● After this, the bot arrives at Checkpoint C.
● Bot passes through the zig-zag path and cross the strip bridge to reach Checkpoint D.
● If bot goes off track on the strip bridge then it has to go back to Checkpoint C.
● Now, the bot has to pick Block 4 and place it in Deposit Zone 4. If the block gets dropped
while moving on the bridge, it has to go again to Checkpoint D.
● After placing the Block 4, if bot falls while descending through stairs, it has to restart from
Deposit Zone 4 instead of going back again to Checkpoint D.
● Bot has to descend through stairs and pick up Block 5 to reach Checkpoint E.
● After this, the bot has to jump from the ramp (inclination of 20 degrees) and land safely in
the Sandbox. If the Block gets dropped while landing, then again it has to go back to
Checkpoint E.
● The bot has to place Block 5 in Deposit Zone 5 while crossing the obstacles.
● Then it has to cross the gate to arrive at the final FINISH mark to finish the run.
● There might be surprise obstacle(s) in the track (images are for descriptive purposes, the
actual track might be different).

GAME RULES

● The bot would be checked for safety before starting and will be disqualified if found unsafe
for other participants.
● Only one team member is allowed to handle the bot. No other team member is allowed to
enter the arena.
● The bot will be liable for disqualification if it causes any kind of damage to the arena.
● The bot is not allowed to slide the blocks against the ground except for fine adjustments in
the Deposit Zone.
● Any damage done to the blocks will lead to immediate disqualification.
● A maximum of 6 minutes will be given to each team.
● The arena has 5 checkpoints. In case the bot gets stuck at any place, then the block it is
carrying (if any) will be repositioned at its initial position and the bot will be kept in the
checkpoints corresponding to that zone. There will be no penalty for this.
● Blocks that are correctly deposited in deposit zones/pushed from the ramp won’t be
disturbed.
● The timer won’t be stopped during this process.
● In case of any disputes/discrepancies, the organizer’s decision will be final and binding.
● The organizers reserve the right to change any or all of the above rules as they deem
fit.
● Change in rules, if any will be highlighted on the website and notified to the registered
teams.

JUDGING

● 30 points will be awarded for successfully crossing hurdles between the START mark and
Checkpoint A.
● 20 points will be awarded for placing Block 1 in Deposit Zone 1.
● 20 points will be awarded for placing Block 2 in Deposit Zone 2 and crossing the wedge,
points will be awarded only once for crossing the wedge. Points will not be awarded if the bot
crosses the wedge multiple times.
● 20 points will be awarded for placing Block 3 in Deposit Zone 3.
● 30 points will be awarded for crossing the zig-zag path and strip bridge combined.
● 20 points will be awarded for placing Block 4 in Deposit Zone 4.
● 60 extra points for crossing the bridge.
● 10 points will be awarded for successfully surpassing the stairs.
● 20 points will be awarded for crossing Checkpoint E.
● 30 points will be awarded to Land safely in the Sand Box while holding Block 5.
● 20 points will be awarded to keep Block 5 in the Deposit Zone 5.
● In case the bot falls/crosses the referred path then 10 points will be deducted and the bot will
be placed at the previous Checkpoint corresponding to that zone as shown in Fig. 1.
