Automatic Pet Feed Dispenser Kit
Automatic Pet Feed Dispenser Kit with Adaptive Soft Robotic Gripper & Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a pet feeding system that cares about every bite. This kit guides you through building a soft robotic arm with a three-fingered gripper — each finger’s stiffness adjusts in real time using air pressure, not rough mechanics. It picks up dry kibble, semi-moist treats, even delicate shreds of wet food without jamming or crushing. Scheduled releases, force feedback, and data logging turn a simple feeder into a personalized, gentle pet care station.
What You'll Build
An automatic pet feed dispenser that combines precision scheduling with a soft robotic manipulator. The Arduino Mega controls three syringe pumps to inflate or deflate silicone fingers, changing their grip strength on-the-fly. A force sensor array prevents over-squeezing, while the OLED shows status and the microSD records every feed cycle. By the end, you’ll have a desk-sized prototype that can be adapted to any pet bowl or diet.
What You'll Learn
- Design and control pneumatic soft actuators using syringes and stepper motors
- Integrate MPX5010 pressure sensors and FSR 402 force sensors for closed-loop grip feedback
- Program real-time scheduling with the DS3231 RTC and log events to a microSD card
- Assemble and solder a multi-module project on prototype PCBs with noise filtering (15× 100nF capacitors)

Who This Kit Is For
This advanced project is designed for B.Tech ECE/EEE students, Smart India Hackathon participants, and hobbyists from IIT/NIT/VIT/BITS engineering ecosystems who want hands-on experience with soft robotics and precision control. It’s ideal for pet-loving makers building a unique smart feeder prototype or adding a gentle manipulator to a home automation research setup.
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?
Open the AI companion via QR code or send a WhatsApp message — it knows every connection, calibration step, and code snippet for this kit, and we’ll personally help if the bot misses something.
Is the soft gripper safe for all types of pet food?
Yes. The three silicone fingers adjust stiffness by inflating or deflating smoothly; force sensors halt movement before crushing even semi-moist or brittle biscuits, so you can handle kibble, extruded pellets, or soft treats without damage.
How does variable stiffness work without liquid metal?
This kit uses air pressure instead of Galinstan. Each finger connects to its own syringe pump via PTFE tubing; the stepper motor drives the syringe plunger to increase or decrease internal air volume, changing the finger’s rigidity instantly. The MPX5010 sensors close the loop for precise stiffness control.
Can I schedule multiple feedings per day?
Absolutely. The DS3231 RTC and Arduino firmware let you program several daily feed times with custom portion grams (calibrated via force sensor weight mapping). All schedules and executed feeds are saved to the microSD for logging.
Pet Care — Galinstan channels in silicone fingers controlled by syringe pumps change stiffness for adaptable grasping.
