We received a request from a transportation equipment manufacturer to create a system that meets the following two objectives for ensuring labor safety compliance in robot welding operations: (1) Establishing a mechanism to prevent unsafe actions (emergency stop) through a two-person operation involving a supervisor (outside the robot operating area) and an operator (inside the robot operating area). (2) Creating a system that prohibits the robot's teaching operation if the operator is not wearing a helmet correctly. 【Details】 - By connecting the signals from helmet-wearing sensors attached to the chin straps of the helmets worn by the supervisor and operator to the poka-yoke receiver TW-800R-EXS, we can achieve a system where "if the operator is not wearing the helmet correctly, the robot will automatically stop" and "if the supervisor determines it to be unsafe, they can remove the chin strap of the helmet to emergency stop the robot." - After the chin strap of the supervisor's and operator's helmets is removed, we will repeatedly customize the software of the helmet-wearing sensor ENS-HH01 and conduct practical verification to ensure the robot stops appropriately within the correct time frame. *For more details, please refer to the PDF document or feel free to contact us.*

We received a request from an automotive parts manufacturer stating, "We want to prevent unlatched (half-locked) conditions during the wire harness connector mating process." In response to our customer's request, we developed a dedicated tool (hereinafter referred to as "Connector Mating Checker") to confirm that the connectors connected to the wire harness used in the customer's production process are in a locked state. By equipping the Connector Mating Checker with the mistake-proofing transmitter TW-800T, we created a system that "wirelessly transmits work performance when it is confirmed that the connectors are in a locked state." 【Mechanical Design】 (1) Wireless transmission occurs only when the connectors are in a locked state. (2) The design allows operators to easily perform confirmation tasks (achieving a size that fits in hand). (3) Confirmation tasks can be performed on connectors located in narrow spaces. Since numerous connectors are used in automobiles, it is expected that this system can be applied to connectors of other shapes, leading to the horizontal deployment of half-lock prevention (mistake-proofing) for connectors. *For more details, please refer to the PDF document or feel free to contact us.
