Students Create Generative Designs for RoboMaster 2019 Supported by Farsoon and Autodesk

Robotics is a multi-disciplinary science involving traditional fields including Mechanical Engineering, Control Systems, Material Science and Information Technology. The latest generation of robotics has paved the way for other fields such as Computer Science, Bionics, as well as advanced manufacturing. The RoboMaster Robotics Competition provides a unique opportunity for young engineers to test their innovation and gain hands-on experience in the field of robotics. Marking its 5th year competing in this international event and having won 2 championships since 2017, the Robotic Team of South China University of Technology (SCUT) has developed a team of experts in Robotics engineering. With 173 participating teams this year, the SCUT team has been seeking brand-new solutions for improved efficiency and quality workflow from design to manufacturing. These young luminaries took their opportunity with using Autodesk Software and Farsoon Additive Manufacturing Technologies.


There are three main challenges: design iteration, weight reduction, and strength requirements. Each year, RoboMaster will announce different requirements that each team needs to tailor their design accordingly for the final contest in 8 months. In order to achieve the best performance of the robot, the design team had to make 4-5 complex “design-build-test” iteration, each cycle including mechanical design, dynamic analysis, structural analysis, assembly, programming, testing, etc.

The object of focus is the stabilizer mount on the robot, a key component which connects the mobile system with the upper projectile system. It is designated to perform complex and rapid movements such as steering, aiming and shooting during the competition, of which the weight reduction of this component has been the key to achieving optimum performance. On the other hand, the robot will experience various extreme conditions including collisions, pellet impact, and vibration during the contest. As the keystone in the robot design, the stabilizer mount requires extreme mechanical strength in order to avoid any damage on the contest field.

In previous designs, the stabilizer mount was limited by the production method, mainly produced by CNC machining with further assembling of up to 27 parts. The weight of these assembled parts could be up to 295 grams, resulting in slower reaction times and movement speeds. In addition, the assembled parts increased the potential for damage during impacts.(Figure 1)


In early 2019, the SCUT team began to adopt Autodesk software and Farsoon Additive Manufacturing Technology to improve the design and manufacturing process. The additive technology offers unprecedented freedom in flexibility of the geometry of design that suits best for the application.

Generative design, a key feature in Autodesk Fusion 360, allows the SCUT team to apply design conditions and criteria for the stabilizer mount, generating a variety of designs to meet the requirements. The students are able to apply a variety of working conditions such as the extreme impact loads during competition to the part. Then define the output options such as desired weight limit (lightweight target), engineering materials (including Resin, Nylon, aluminum), safety factor (up to 8) and potential processing method (CNC, milling, additive), etc. This ensures the best performance of the part during the contest. All the options generated have been further explored and tested by the students, in order to choose the optimal design for final manufacturing (figure 2). 3 designs are chosen with different materials and processing methods for assembly and field validation: Resin (Stereolithography), Nylon (Plastic Laser sintering) and Aluminum (Metal Laser Melting). The Resin and Nylon parts broke in the field impact, while the AlSi10Mg aluminum stabilizer mount produced by Farsoon FS271M metal laser melting technology stands out with its qualified strength, durability, and performance (Figure 1).

This combination of generative design and additive manufacturing completely overturns the concept of a traditional design process. It creates the optimal design in a very short time without the limitations of traditional processing and materials options.

The optimized additive manufacturing stabilizer mount achieved a final weight of 170 grams – a 42% weight reduction compared to the original CNC process. The lighter weight means a faster response to signals and improved mobility in the field. Simultaneously, by combining 27 parts to only 1 single part, it reduces the material waste while enhancing the strength by generativity adding support, therefore reducing the mass of the robot while ensuring structural integrity.

This new workflow also helps accelerate design iteration from the development process to manufacturing. The traditional design by engineer is limited by his own experience, while generative design employs cloud computing to help generate and iterate the optimal result. Compared to traditional manufacturing, additive technology can build 2 sets of stabilizers in only 2 days (Figure 3). The whole workflow is simplified with improved efficiency meanwhile it offers the best solutions for application.

Faster design iteration helps the SCUT team to work more efficiently while reducing the cost of material and manufacturing. This year, SCUT team achieved significant cost reduction to research and development. For example, the mechanical team’s entire iterative cost was reduced by 80%, which would not have been possible before.

With the help of additive technology, the SCUT team entered the RoboMaster (South-China area) contest on May 23, 2019. The optimized design and improved performance of the stabilizer mount enabled the SCUT team to win the Championship despite intense competition. (Figure 4)

 “Generative design and additive manufacturing have opened up a new horizon from tradition process,” Said Zhang Dong, Associate Professor of School of Mechanical and Automotive Engineering and Tutor of Robotics Laboratory, “ It helped us find the solution to the key design challenges caused by material limitations and processing methods, which greatly accelerates the design process and reduces production costs. Although we have only achieved 42% weight reduction for one single part, but when you pursuing the perfection, ultimate design of each part is necessary in the future. Taking this new path is exciting yet challenging, but we are confident that only with the technology of innovation, we will make a difference.”
