Where I am walking into a light screen where the robot is picking off the operator side of a turn table, while work is being performed on the other side. I am using the standard formula of US CAN: Ds =K x(Ts + Tc + Tr + Tbm) + Dpf. I was able to find values for each, but the standard K constant of 1600 mm/sec doesn't seem to be the correct constant for this scenario. Ds=('K'*(600+50+23))+78.625. K is a hand speed constant and as my feet and hands can move I would think the value would increase. The standard says it could be 1600-2500 and that would be determined through a risk assessment. How do I determine a speed constant through a risk assessment?

Hi. We have a motorman robot with fronius welling equipment. Our programmer is no longer in the company. We need to modify an existing program by making fillet welds larger. Have tried a few things with no luck. Any ideas?

Dear Experts , we want to guide a robotic welding arm to weld reinforcement steel mesh structures. These structures are up to 40 meters long, 2 meters high and 1.5 meters wide . They are used for bridge beams which our client makes for major freeway bridge construction. The weld mesh structures are then lowered into the molds where they fill the molds with concrete . They thread through the mesh pre-stressed steel cable before they pour the concrete. We would like to use a gantry mounted robotic arm which would travel along and above the weld mesh cages and the robotic welder would spot weld at a given interval at the intersection of the mesh to hold the structure together, instead of tie wire . The issue is that the mesh is never the same so we would need to scan the mesh ahead of the welding tip so to create a model, something like using SLAM process. This way the robot would know where to weld and its position at each steel rod cross section of the mesh that needs welding . I am wondering is there such a device already available or would we need to integrate the Lidar and the robotic arm ourselves. We have a client that has asked us to investigate the potential . We are look for a partner or a specialist to contract to help us with the application. Please contact me at brian@3dx.com.au . Regards Brian Rowland

What are the minimum requirements for guarding an articulated arm robot?

Is there a programming methodology for Motoman DX100 or DX200 that allows for the specification of a series of welds with reference to a dictated origin, that allows for that series of welds to be copied multiple times with an offset referencing the dictated origin? eg, welding a part sequence that is repeated multiple times a specific distance apart. I would only want to do this to get the bulk of the points entered, then change from an offset reference to just the individual points so it is easier for an operator to read/understand/manipulate.

I am a director for a workforce development division of a community college and we are considering a welding robot due to the large volume of manufacturers in the region. Though our program is "non-credit" I believe allowing the GMAW students to become familiar with robotic welding operations will make them more appealing to potential employers. I have considered a turnkey system but wondered if purchasing all of the components and utilizing our existing power sources would be a good option.

I've seen a number of references to a requirement minimum distance between a robot and guarding, specifically to prevent trapping a person between the robot and guard. I have been able to find no other requirement, and infact in ANSI/RIA R15.06-2012, Part 2 5.4.2 Establishing safeguards and restricted spaces, it states "The perimeter safeguards shall not be installed closer to the hazard than the restricted space. If the perimeter safeguard is designed to be the limiting device in accordance with 5.4.3, then the perimeter safeguard establishes a portion of the boundary for both the safeguarded and restricted spaces." This means the guard (provided it meets 5.4.3 requirements) can be used to stop the robot- obviously not a 'best practice' but still possible. So- where is this crushing distance coming from? 5.5.1 mentions "where crushing is prevented by the maintaining of minimum gaps, they shall meet the requirements in ISO 13854." but I'm not completely sure what "Where crushing is prevented..." really means. I've seen many, many cells that do not have any distance between the restricted space and the guards.

I am wondering what kind of safety features are available for a robotic arm to operate without being confined to a designated work cell? Is there a type of light curtain or occupancy sensors available? Any help at all on this matter would be great.

What are the best resources to learn more about end of arm tool (EOAT) design for automotive material handling applications? Topics that I am interested in: - Interface design of tooling to robot (Specific to robot manufacturer or standard COTS interface plates) - support structure or frame (weldment vs. modular aluminum extrusion) - linear actuator selection criteria (pneumatic vs. electric) - location features on tooling (NAAMS pins, v-blocks, net pads, machined plastic) - non-marring materials for clamping interface to painted parts (UHMWPE, delrin, others?) - vision systems (correction/best fit systems such as robeye, Fanuc IRvision, 3D vision system) Also interested in end of arm tooling component suppliers, turnkey EOAT design Thanks

Hi! I have a question about the safety in an industrial robot cell. My goal is to reduce the risk of collisions of the robot with the fence or the cell. Therefore I am in need of safety systems and solutions, which are capable of doing this. I would be very happy about people i can contact and talk about possibilities and theories. Thank you for your help in advance.

I want to reduce the size of a safeguarding of a workstation but I do not know the specifications that I have to follow. Could you help me please? Thanks.

We have a large respot line that has 54 robots and is 200 feet long. The line 65 units per hour. R15.06, 10.8.4 -f states that only one person shall be allowed in the safeguarded space in T2. That is not practical. We must perform other tasks on other robots in other stages at the same time. Can I do this with a risk assessment based on our procedures?

We are an agrochemical company, with many sizes for finished products (1.0 liters, 5 L, 10L, 20L). We are looking in the market of automation for packaging lines. A basic question I have is, which is the best solution, cartesian or Anthropomorphic robot?

What do you see as the future for robots replacing human doing complex tasks like what an electrical lineman does? I am curious if you feel this is near or short term in the future. I feel where robots could replace humans that do repetitive tasks but not sure when it comes to complex tasks where we currently rely on the human to make decisions on the fly.

I've got a question about robots for Injection Molding Machines. Do you have to buy a robot specifically "designed" for IMM (like a Yushin or a Sepro etc.) or would any articulated (e.g. a Epson) or any Cartesian robot be ok? When do you choose articulated vs. Cartesian robot, and vice-versa? Conversely, is a robot for IMM useful for any other application? Thank you for your time !

Do collaborative robots have/require a different risk assessment than traditional robots? If so, would you please direct me to some websites with examples of collaborative robot-specific risk assessments?
