Designing a Combat Robot: Basics & Tips to Remember

Designing your Combat Robot

  1. Define Objectives and Requirements: Start by clearly defining the objectives and requirements of the combat robot. Consider factors such as weight class, competition rules, desired capabilities (e.g., speed, agility, durability, weapon effectiveness), and team preferences. This will serve as the basis for the design.
  2. Conceptualization and Brainstorming: Encourage team members to brainstorm ideas and concepts for the robot design. Consider different approaches, configurations, and strategies based on the defined objectives and requirements. Sketch out rough concepts and discuss their merits and drawbacks as a team.
  3. calculation- make calculations for drive system ,weapon system and battery system. various calculators available in market for these calculations. Please check drive calculator from ask Aaron, weapon calculator and battery calculation with gyro and bite angle calculations
  4. Research and Analysis: Conduct research on existing combat robots, competition strategies, and design principles. Analyze successful designs and identify key factors contributing to their effectiveness. Learn from past competitions and incorporate lessons learned into the design process.
  5. Create Detailed Plans and CAD Models: Once the team has settled on a conceptual design, translate it into detailed plans and CAD (Computer-Aided Design) models. Use CAD software to create precise 3D models of the robot, including its chassis, components, and weapon system. Pay close attention to dimensions, clearances, and integration of components.
  6. Iterate and Refine: Iterate on the design through multiple rounds of feedback, testing, and refinement. Solicit input from team members, mentors, and advisors to identify areas for improvement and address any issues or concerns. Make adjustments to the design as needed to optimize performance, functionality, and reliability.

 

Considerations for Specific Components:

   – Chassis: Choose a chassis design that provides a balance of strength, durability, and weight efficiency. Consider materials such as aluminum, steel, or composite materials, and design the chassis to accommodate other components and support the overall structure of the robot. Also make a market survey whether the components available to your local market or not.

   – Weapon System: Select a weapon system that aligns with the team’s strategy and objectives. Whether it’s a spinning blade, flipper, hammer, or other weapon type, design the system to deliver maximum impact while minimizing weight and power consumption.

   – Electronics and Control System: Design the electronics and control system to provide reliable operation and precise control of the robot. Consider factors such as wiring layout, component placement, and compatibility with the chosen radio control system.

 

By following these steps, the team can develop a well-thought-out and effective design for their combat robot, setting the stage for successful construction, testing, and competition. Effective design is key to building a robot that performs reliably and competitively in the arena.
