Construct a Pressure-Sensitive Soft Robotic Hand That Gently Grasps Sport Bottles — Arduino Mega Included

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 hand that curls five silicone fingers around a sport bottle with just the right force — never crushing it, never dropping it. This kit equips you to build exactly that: a soft gripper where each finger inflates independently via a solenoid valve and reports its grip pressure back to an Arduino Mega. Whether you are prototyping a human-robot interaction demo or exploring compliant end-effectors, the real-time pressure monitoring turns an ordinary bottle gripper into a closed-loop control lab.

What You'll Build

You will assemble a fully functional five-finger pneumatic gripper. Each silicone finger connects to a 12V solenoid valve that regulates airflow from a mini compressor, while five MPX5010 pressure sensors provide granular force data shown on a crisp OLED display. The completed system gently cups and lifts a sport bottle, maintaining consistent pressure even on a textured or flexible surface — an ideal testbed for robotic gripping research.

What You'll Learn

• Pneumatic circuit design with solenoid valves, diodes, and capacitors for noise-free switching
• Interfacing MPX5010 analog pressure sensors and mapping voltage to grip force
• Proportional control of multiple pneumatic channels using Arduino Mega and relay modules
• Soldering and assembling a reliable air handling system on prototype PCBs

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Robotics researchers and mechatronics enthusiasts who need a plug-and-play soft actuation platform. B.Tech ECE/EEE students tackling final-year projects or competition entries like Smart India Hackathon will find the closed-loop pneumatic system a standout feature. IIT, NIT, and VIT research labs can use it to prototype adaptive grippers without fabricating custom electronics.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
