Soft Robotics Pneumatic Finger Array
Build a Soft Robotic Gripper with Arduino Mega: Pneumatic Finger Array Kit
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 gripper that can gently hold an egg or a fragile glass without crushing it. This kit brings soft robotics to life, letting you control five pneumatic fingers individually and measure exact grip pressure—ideal for advanced robotics labs, biomechanics research, or industrial automation prototyping.
What You'll Build
A five-finger soft robotic gripper that inflates and deflates on command, with live pressure feedback shown on an OLED display. The system uses an Arduino Mega to orchestrate 5 solenoid valves and read 5 analog pressure sensors, giving you complete control over each finger’s grip force. You'll solder and assemble the entire pneumatic control circuit from scratch, then test it on real objects.
What You'll Learn
- Wiring and programming a multi-channel pneumatic control system with Arduino Mega, including timing sequences for sequential finger inflation
- Interfacing MPX5010 pressure sensors and calibrating analog readings to precise grip force (N)
- Driving 12V solenoid valves via 4-channel relay modules and protecting circuits with flyback diodes and snubber capacitors
- Integrating a 0.96-inch OLED display for real-time pressure monitoring and system diagnostics

Who This Kit Is For
This kit is built for final-year B.Tech ECE and EEE students working on advanced robotics capstone projects, M.Tech researchers exploring soft actuators, and teams in Smart India Hackathon. It’s also a perfect fit for robotics labs at IITs, NITs, VIT, and BITS Pilani that need a ready-to-build pneumatic gripper platform for research papers.
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.
What if I get stuck during the build?
Scan the QR code inside the box to launch your AI build companion trained on this exact kit. It walks you through each step and is backed by WhatsApp support from our team of engineers.
Are the soft fingers pre-made, or do I fabricate them from the silicone tube?
The kit includes high-quality silicone tube that you shape into five pneumatic fingers following detailed build instructions. No additional molds or curing required—just cutting and sealing with the provided materials.
What is the gripping force and what objects can it handle?
With the included 12V mini compressor and 6mm tube, each finger can generate enough force to pick up objects up to 500g. The pressure sensors let you fine-tune the force to handle delicate items like eggs or small glass vials without damage.
Is this suitable for a soft robotics research project?
Absolutely. This kit provides a complete pneumatic control and sensing platform that’s ideal for prototyping soft grippers. The direct pressure feedback from MPX5010 sensors gives you quantitative data for biomechanics papers or automation research.
Five individually controllable silicone fingers inflated by 5 solenoid valves. Pressure sensors confirm grip force.
