Soft Robot Pneumatic Actuator Kit: Build a Muscle-Like Gripper with Arduino PID Control

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a robotic finger that curls and uncurls like a human muscle — soft, silent, and adaptable. This kit turns that idea into reality using a peristaltic pump to precisely inflate a silicone tube, with an MPX5010 pressure sensor feeding real-time data to Arduino for PID control. Whether you're prototyping a soft gripper for delicate fruit handling or exploring bio-inspired robotics, this build gives you hands-on experience with closed-loop pneumatic systems.

What You'll Build

You’ll fabricate a soft actuator by sealing a silicone tube, connecting it to a mini peristaltic pump driven by an L298N motor driver. The Arduino Uno reads pressure via MPX5010 and dynamically adjusts pump speed to maintain a set pressure level — the same principle used in industrial soft grippers. The 0.96-inch OLED displays live pressure, setpoint, and PID output, so you can watch the control loop in action.

What You'll Learn

• Closed-loop PID control for pneumatic systems
• Interfacing MPX5010 pressure sensor and L298N motor driver with Arduino
• Building and calibrating a soft robotic actuator from a silicone tube
• Visualizing feedback loops and tuning PID gains on an OLED display
