Mavrick RBTX – Student Combat Robotics Team

Mavrick RBTX is a student robotics team from West Bengal, India, focused on designing, building, and competing with high-performance robots. Our team consists of engineering students passionate about mechanical design, electronics, manufacturing, simulation, and robotics.

Our team has extensive hands-on experience in competitive combat robotics, with multiple competition participations and winning results across different weight categories. Over our previous projects, we have developed and competed with robots in the 3 kg, 5 kg, and 8 kg categories.

We have achieved multiple winning results in competitions, and the photograph included with this project is one example of our team's previous competition achievements, featuring one of our winning 5 kg combat robots.

Our previous projects have given us practical experience in mechanical design, CAD, fabrication, electronics, drivetrain development, weapon systems, testing, repairs, and competition operations.

We are now using the experience gained from these previous robots to develop our next-generation 8 kg combat robot, with a stronger focus on engineering analysis, precision manufacturing, reliability, and performance.

Current Project – 8 kg Combat Robot

Our current project is an 8 kg combat robot built around a high-energy vertical spinning weapon.

The robot uses a 1.8 kg single-tooth vertical spinning weapon with a thickness of 25 mm and a maximum weapon radius of approximately 85 mm. The weapon is designed to operate at approximately 10,000 RPM, giving the weapon a tip speed of approximately 89 m/s.

Because of the high rotational speed and impact forces involved, the weapon requires careful consideration of material selection, structural strength, machining accuracy, balancing, bearing alignment, and overall manufacturing quality.

The weapon is planned to be manufactured from hardened S7 tool steel with a target hardness of approximately 50 HRC.

The robot also uses a high-performance brushless motor and belt-driven weapon system. The weapon is mounted on a fixed shaft and supported by multiple bearings to provide the required rigidity and alignment during operation.

Our team is currently working on the complete CAD design and engineering analysis of the robot, including the weapon, chassis, drivetrain, bearing supports, motor mounts, and other structural components.

Manufacturing Requirements

One of the biggest challenges for our student team is manufacturing the large and precision-critical mechanical components required for the robot.

The most important components that we need to manufacture are the combat weapon and the main robot chassis.

The weapon requires machining from S7 tool steel followed by appropriate heat treatment to achieve the required hardness. Since the weapon will operate at approximately 10,000 RPM, accurate machining, dimensional control, balancing, and surface finish are extremely important.

The main chassis also requires strong and accurately manufactured metal components capable of withstanding the impact forces generated during combat.

In addition to these major components, we require several custom-machined parts including:

Hardened S7 steel combat weapon

Main robot chassis and structural components

Custom weapon shaft

Bearing supports and bearing housings

Weapon pulley for the belt-drive system

Weapon motor mount

Drive motor mounts

Spacers, brackets, and other mechanical components

PCBWay's Support

As a student team, we have the ability to design and analyze these components, but manufacturing them to the required accuracy and strength is one of our biggest challenges.

PCBWay's CNC machining and manufacturing capabilities would allow us to transform our CAD designs into high-quality physical components.

Support from PCBWay would be particularly valuable for manufacturing our S7 steel weapon and robot chassis, which are the most important and difficult components of the project.

Professional manufacturing would allow us to improve the dimensional accuracy, structural reliability, alignment, and overall quality of our robot.

It would also allow our students to experience the complete engineering workflow:

CAD design → FEA → Design optimization → CNC manufacturing → Assembly → Testing → Competition

This experience would benefit not only the current robot, but also future projects developed by our team.

Engineering and Development

We are using CAD and engineering simulation to evaluate the robot before manufacturing.

For the weapon, our analysis includes rotational dynamics, centrifugal loading, structural stresses, bearing loads, shaft stresses, and impact conditions.

The robot chassis is being designed with a focus on strength, stiffness, weight distribution, manufacturability, and protection of the internal components.

We are also working with Scorpion Power System, which is supporting our project with the weapon motor.

The combination of professional power-system components and student-designed mechanical systems gives us the opportunity to build a high-performance robot while gaining practical engineering experience.

Looking Forward

Mavrick RBTX aims to continue developing increasingly advanced robotic systems and to encourage more students to participate in mechanical engineering, electronics, manufacturing, and robotics.

Our experience across multiple competitions and weight categories provides a strong foundation for our current project. The lessons learned from our previous 3 kg, 5 kg, and 8 kg robots are being incorporated into the new design.

Our goal with the new 8 kg robot is not only to compete, but also to demonstrate what a student engineering team can achieve by combining advanced CAD, simulation, professional manufacturing, and hands-on testing.

We believe that PCBWay's support would allow us to overcome one of the biggest barriers faced by student engineering teams: access to professional manufacturing.

With PCBWay's support, we would be able to manufacture our designs to a much higher standard and demonstrate the complete journey from a student CAD model to a competition-ready machine.

We would be proud to collaborate with PCBWay as our manufacturing partner and showcase PCBWay-manufactured components throughout our build, testing, and competition journey.

We can provide our CAD models, engineering drawings, material specifications, FEA results, component requirements, competition details, photographs, and other project information upon request.

We would be very excited to work with PCBWay and together demonstrate what a student engineering team can achieve with access to professional manufacturing technology.
