RoboticMaterials believes that future robots will not just be made of gears, links and joints but mimic the tight integration of sensing, actuation, computation and communication found in natural systems. We focus on providing tactile sensing with super-human capabilities to the robotic industry by providing our patent-pending technology for proximity and force sensing as retro-fit kits for popular robotic platforms including Rethink Robotics Baxter, Kinova arms and RobotiQ grippers. We believe that contact sensing is critical for successful manipulation and being able to see an object before contact to be even better. As properly using the sense of touch for manipulation is not trivial, we are also providing a full-stack perception and manipulation solution based on ROS, PCL, OpenCV and MoveIt!
Why tactile sensing? Robotic manipulation relies on providing sufficient constraints to an object. The problem is that to continue to exert force after contact has been made will induce motion in the object, making it harder to successfully complete the grasp. RoboticMaterials sensors can help here, by allowing the robot to determine the point of zero distance and zero force. At the same time, proximity reading helps to align the gripper/hand with the object before contact is made.
Principle of operation – Our sensors use infrared proximity sensing embedded in transparent, abrasive resistant polymer. In addition to provide the robot with the right amount of “grip” and being easy to clean, this enables proximity sensing at a distance and force sensing due to internal reflection and deformation of the polymer. Changing polymer mixing rates and thickness allows tuning a wide dynamic range and allows robots to handle a large variety of items ranging from highly corrosive to food grade. Using infrared makes RoboticMaterials sensors sensitive to a surface’s color (or better, its reflectivity). Due to change in response from the signal traveling through air or rubber, it is yet possible to detect contact and thereby allows to infer the material properties.
Research – We are closely working with the University of Colorado and our customers to find new applications for RoboticMaterials’ sensors and to push the boundary of robotic sensing.
