Event Overview:

• Event Name: Grab-o-tron: The Ultimate Test of Robotic Precision and Power.
• Cluster: MakerSpace Cluster
• Event Type: Bot
• Mode: Online
• Team Size: 4 per team
• Duration: 9:00 AM – 1:00PM

Event Task / Objective:

• Grab-O-Tron is a robotics challenge designed to test innovation, precision, and control.
• Participants must design, build, and program a robot capable of grasping and transporting objects within a defined arena.
• The event consists of 2 progressively challenging rounds, where robots must pick and place objects of varying shapes, positions, and weights (50–100 g) at distances ranging from 2–3 meters.
• Teams will be evaluated based on accuracy, mechanical design, programming efficiency, object handling, and completion time.

Design / Technical Specifications:

• The robot must fit inside a 40 cm × 40 cm square at all times.
• Maximum robot weight: 3 kg, including all electronic and mechanical components.
• The bot must be remote controlled (through controllers, mobile, laptop or any application).
• Objects will be placed 2–3 meters away from the starting point.
• Bot must execute: approach → pick → transport → place. If an object is dropped, a penalty will be imposed.
• Allowed components:
• Microcontrollers (Arduino, ESP32, Raspberry Pi, etc.)
• Motors (servo/stepper/DC)
• Any safe gripper (mechanical, magnetic, suction, etc.)
• Prohibited:
• Dangerous tools, blades, projectiles, open flames
• Pre-built commercial robots (DIY and custom builds only)
• High-voltage components beyond safe limits
• Robots must operate safely without damaging the arena or surroundings.

General Guidelines:

• Participants must adhere strictly to the event schedule.
• Teams are responsible for their own tools, laptops, batteries, chargers, and spares.
• All robots must be designed and built from scratch for this competition.
• Documentation must include:
• Problem statement
• Design approach & materials
• Logic flow
• Algorithms used
• Challenges & solutions
• Power supply and basic connectivity will be provided by organizers.
• Any dangerous, unethical, or disruptive behavior will result in disqualification.
• Team members must remain within designated operational areas.

Safety Rules:

• All equipment must comply with safety regulations.
• All batteries, wiring, and mechanical systems must be securely mounted.
• No sharp edges, exposed rotating parts, or unstable assemblies.
• No hazardous materials, high-voltage systems, or explosive components.
• Spectators must stay outside marked zones.
• Only participating teams and volunteers may handle robots inside the arena.

Event Rounds / Structure:

• Round 1 – Dynamic shapes (Qualification)
• 2 objects of different shapes will be placed in 2 different checkpoints on the track.
• Duration: 90 min
• Round 2 – Weighted objects (Finals)
• 2 objects of different weights will be placed in 2 different checkpoints on the track.
• Duration: 60 min
• Final Evaluation
• Judging, Demo, Results

Round 1 – Dynamic Shapes (Qualification):

• Objective:
• Test the robot’s ability to handle objects of different shapes.
• Details:
• 2 objects of different shapes will be placed at 2 different checkpoints on the track.
• The robot must pick and place each object into the designated target area under remote control.
• Objects:
• Cube (side=4cm, weight ≈ 10g)
• Sphere (radius=2.5cm, weight ≈ 10g)
• Evaluation:
• Successful handling of different shapes, grip adaptability, placement accuracy, and control stability.

Round 2 – Weighted Objects (Finals):

• Objective:
• Evaluate the robot’s ability to handle objects of varying weights.
• Details:
• 2 objects of different weights will be placed at 2 different checkpoints on the track.
• The robot must safely pick and place the objects without dropping or misplacing them.
• Objects:
• Cube (side=4cm, weight ≈ 50g)
• Cylinder (height=5cm, radius=2.5cm, weight ≈ 100g)
• Evaluation:
• Ability to lift varying weights, grip strength control, object safety, and successful placement.

Arena Setup:

• Arena setup will be provided during the event.

Submission Guidelines:

• Final submissions must include:
• Working prototype/robot demo
• Technical report or PPT (design, code, components)
• Source code/circuit diagram
• On-time physical submission before the designated round
• Video proof if any round requires validation
