The User Datagram Protocol (UDP) is a robust method for communicating with haptic devices across a Local Area Network (LAN), enabling fast Ethernet transmission and remote operation. Because haptic devices are constrained by update rate requirements, considerations must be made in authoring reliable UDP software for them. Effects on UDP transmission speed by communications software, device firmware, and 3rd-party software are analyzed theoretically and experimentally. Results indicate effective methodologies in the design and construction of efficient haptic devices that rely on UDP transmissions. The benefits and disadvantages of the use of UDP in haptic device communications will also be discussed.
