3DMart, a robotics project we've been collaborating on in recent years, is finally being revealed! Featuring a physical robot from Taiwan, incorporating new control system technology and highly mobile assistive technology , we hope to share the entire design and creation process with robot developers and enthusiasts. Below is a documentary video showcasing our most popular creation:
Original design
In the early stages of project execution, whether dealing with clients or the team, rapid revisions and communication through drawings are essential. Defining the objectives is crucial before proceeding with engineering analysis, and this process requires significant time and capital investment. However, sketching is not merely engineering; it must combine science and art to efficiently develop concepts and present them to the team and clients.
Challenges
One of the key goals of developing new exoskeletons is to enable people to wear them and perform complex tasks, such as reducing workload, enhancing combat effectiveness, or reducing workplace injuries. There are also plans to expand to include lightweight assistive devices for the shoulder, knee, and elbow joints in the future; therefore, weight must be considered, as using all-metal would increase the difficulty of use.
Solution
In terms of the exoskeleton's functionality, relatively low-cost yet robust and durable materials are required, such as carbon fiber and PLA instead of metal. To manufacture aesthetically pleasing curved shells and sensor components while avoiding the expense and time-consuming process of mold making , using 3D printing to develop the sensor structure and shape is the best choice; and this part is also a key element of the entire robot.
Since the sensor structure, housing, and computer board are key technologies, the precision of 3D printers must be demanding, and the machines and slicing software for supporting materials must be reduced in order to save time and R&D costs and present a smooth appearance and good assembly structure; and the Ultimaker 3D printer can achieve such quality.
Every large project must undergo small robotic arm experiments and parameter calibration before large robot testing can proceed. Therefore, all robot modules are 3D printed . Thanks to the Ultimaker 3D printer, which can produce high-precision complex parts, rapid prototyping is possible to validate ideas, saving design time and R&D costs. These small robotic arms also facilitate subsequent obstacle removal and analysis.
Current achievements
The machine currently weighs approximately 30 kg and is 170 cm tall. The exoskeleton utilizes a novel composite structure and bonding technology. The carbon fiber rod material can withstand a test of over 80 kg, weighs less than 400 grams, and is 80 cm long. The core sensor mechanism and numerous complex shells in the project were sponsored and 3D printed by 3DMart .
The entire exoskeleton project extends to several important technologies and tools, such as exoskeleton control technology and robot design software. In addition to structural innovations, the core technology is the control system, which can currently lift objects weighing around 10 kg. The software helps developers conduct project analysis and verification and present them beautifully to clients.
