I can turn them on and off in the larger assembly in the model. All the sub parts and the assembly show LCS's at the necessary bolt hole. Now, I have to attach another part ot this assembly in the larger assembly. The issue I am having is I have an assembly that is made up of 6 parts that form a shape that I need to attach to a larger assembly that I have created an LCS for the bolt hole and it works. I am working on a project that I have put together as a massive assembly but it is being changed and I have decided to break the one large assembly into multiple smaller assemblies. I don't know if I can do what I want to do or it is a bug. 18, issue 3, 2021.Hello, I need some help with LCS's and Assembly 4 with nested assemblies. Yotto Koga, Heather Kerrick, Sachin Chitta, On CAD Informed Adaptive Robotic Assembly, in IEEE/RSJ International Conference on Intelligent Robots and Systems, Kyoto, Japan, Oct. Sachin Chitta is a Director of Research Science at Autodesk. We’re excited about what we’ve got going for this year so look for more as our research progresses! Our research is targeted at bridging part of this gap by giving designers the ability to program robotic workcells capable of assembling their designs. However, there is a noticeable gap between the design and make parts of this workflow – manufacturing constraints are not always incorporated into the design process from the beginning while the make process is very manual and often siloed from the design phase. Our products are also used to model, simulate, and design the make or manufacturing processes to bring those product assemblies to life. So, what does our work intend to contribute? Autodesk’s software products are used every day by millions of people to design new product assemblies. Using the onboard cameras though, it can still make the small adjustments to make all this work. An important note here is that one of the robots is not very accurate – it doesn’t know where it is very well. They then hand off the part to each other to orient them the right way before inserting them into the assembly. Using onboard cameras, each robot helps the other figure out where the part is in their hand. Robot grippers are not very dexterous as compared to human hands so cannot manipulate parts in-hand like we can. As the robots pick the blocks, they often end up misaligned in the robot’s hand. The blocks are initially arranged in a random pile on a table. We demonstrate this on a challenging task where a pair of robots work together to build a 3D lattice structure from Yinan blocks (small 3D-printed components named after their creator). We use CAD data in multiple ways: in an interactive tool to specify high-level input for the assembly process, to train a perception model capable of picking and re-orienting random parts, and to simulate and validate the different parts of our assembly plans. However, CAD data of the parts and product assemblies themselves are a rich source of information. CAD data has traditionally been used in robotics to guide collision checking and visualization. In recent research published at the IEEE/RSJ IROS conference in Kyoto, Japan in October 2022, we’ve been examining the use of CAD data to help overcome some of these obstacles. This lack of adaptivity makes some tasks hard to automate. Traditional automation systems, for example, struggle when parts are presented in unstructured piles inside a bin versus being neatly lined up on a fixture. Automation is also hampered by the inability to adjust (or adapt) to variations in parts or the process. In some industries, product lines change every year (or even faster) making changes in automation prohibitively expensive. Fixed automation is designed to manufacture one product but cannot be repurposed easily when the product changes. A primary reason is the lack of flexibility in automated systems. Industrial assembly is still one of the most manual tasks in manufacturing.
