While many industries and applications can use off-the-shelf joints to effectively and reliably perform their intended tasks, some application areas will often require custom joints simply because their performance or environmental requirements are beyond the capabilities of commercially available joints. In these extreme environments, the custom flight control requirement will dictate a bespoke design, specialized materials, and unique performance characteristics.
Some typical tasks which require custom joints are:
- Space Robotics and Satellites
Custom joints must be able to perform in vacuum conditions, withstand the experience of launch vibrations and extreme temperature variations, while lightweight, radiation tolerant, and thermally stable materials must be introduced in the design.
In oceans at extreme depths, the pressure is extreme, therefore joints must be designed to be pressure sealed, corrosion resistant, and reliable while operating near freezing temperatures. The materials used for deep-sea exploration typically include titanium and marine-grade alloys.
- Military and Defense Systems
Many applications such as unmanned ground vehicles (UGVs) or robotic weapon platforms will require a rugged joint, capable of withstanding shock, dust, vibration, and electromagnetic interference (EMI).
- Medical Robotics and Tools
Precision, sterility, and biocompatibility are needed in medical systems. Custom joints can be designed to suit new, small-scale, minimally invasive, robotic systems that could incorporate sensor technology allowing for real-time feedback.
- Nuclear or Hazardous Site Robotics
Custom joints will generally be required in areas where radiation, excess heat, or corrosive chemicals will not only compromise your joint, but also put the operator or user in jeopardy. Maintenance-free and robust sealing may even be a requirement in such environments.
- Automated Manufacturing in Harsh Environments
In general, heavy industries (such as steel mills or chemical plants) will demand high-speed automated locomotion. Joints operating in heavy industry usually mean heat sealed joints that will only seal dust that is generated at high speed.
In all these areas, custom joint design is the only way to achieve reliable, long-term performance under conditions where standard components would fail.
