Focus on Robotics 1-Hour Workshop
As the use of robotics expands into a broadening spectrum of markets — agriculture, defense, medical, industrial… robotic technology is evolving as well to meet the tailored performance requirements of these diverse markets. To address the demands for precise, reliable automation, electromechanical clutches and brakes are an ideal fit for their clean, quiet, dependable performance as well as their ease of installation, simplicity of design and control, and compact power. Clutches and brakes have transformed in recent years to specifically address these needs for high quality, precision and reliability. For our customers and OEM designers that can benefit from this information, we offer an educational lunch & learn seminar covering recent technology updates in our field.

Robotics Application Example
A robot developer asked SEPAC to design and manufacturer a spring-set, power-off brake for a humanoid robot with critically enhanced dexterity performance. The agility advantage of the designed allowed the robot to perform very realistic and necessary mechanical first responder tasks in emergency situations such as opening/closing doors and hatches, connecting a fire hose to a valve, etc.
The design had to be relatively thin with high torque holding capacity, and the lighter the brake design the better for the performance of the humanoid robotic arm. Adding to the challenge, the completed brake design and final hardware had to be installed very early in the design/build process so that the sophisticated control logic could be matched to the physical performance characteristics.
Working within a tight schedule and limited budgets, SEPAC made several iterations of the brake for different joints in the robotic arms. The complexity and pace of the project was high as the robot was part of a DARPA (Defense Advanced Research Projects Agency) competition. The SEPAC brakes performed well; the robot secured a high score and moved onto a higher level of this government-funded competition. The intent is that, one day, this robot may help save lives while safeguarding the lives of the first responders it is programmed to serve. SEPAC enjoyed being a part of this successful team effort.
