Cobots are a class of passive robotic devices that utilize steering joints to impose nonholonomic constraints on their joints. These steering joints are a subclass of transmission called Continuous Variable Transmission, CVT. Here we purpose to develop a cobot that utilizes a CVT joint based on flow rate divider of pneumatic actuators. We studied characteristics of a valve and a cylinder. We designed and built a multi channel flow divider. Furthermore, to test our concept we constructed a simple x-y pneumatic cobot.
