Why are pneumatic actuators (i.e. Air Muscles) used so rarely in the field of robotics?

Despite these challenges, pneumatic actuators are being explored in niche applications, particularly in soft robotics, where their compliance and adaptability can provide unique benefits. As technology advances and new materials emerge, we may see a resurgence of interest in pneumatic systems in robotics. For more Information: https://qr.ae/p2w9tV
