Precision Linear Positioner Kit
Achieve Industrial-Grade Adaptive Grasping with the Precision Linear Positioner Kit (Arduino Mega 2560)
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Construct a robotic gripper that adapts its finger stiffness in real time using galinstan-filled silicone channels. This kit lets you build a fluidic actuation system where three syringe pumps, driven by stepper motors, precisely pressurize liquid metal inside soft fingers. Ideal for industrial automation tasks requiring gentle yet firm handling of fragile objects—from glass vials to deformable food items.
What You'll Build
You will assemble a three-finger adaptive gripper with independent stiffness control. The Arduino Mega 2560 reads force feedback from FSR 402 sensors and pressure signals from MPX5010 transducers, then adjusts stepper motor-driven syringes to modulate galinstan pressure. All data is timestamped with a DS3231 RTC, logged to a MicroSD card, and displayed on a 0.96-inch OLED. The result is a gripper that stiffens when you need to hold a heavier object and softens for delicate contact.
What You'll Learn
- Closed-loop control of stepper motors for precise fluid dispensing
- Interfacing FSR 402 force sensors and MPX5010 pressure sensors with Arduino
- Implementing real-time data logging with DS3231 RTC and MicroSD module
- Design and assembly of soft robotic actuators with galinstan channels

Who This Kit Is For
Engineers, researchers, and advanced makers working on soft robotics or adaptive automation. It's designed for B.Tech ECE/EEE/Mechanical students tackling final-year projects, M.Tech candidates exploring flexible grippers, and participants in Smart India Hackathon or IIT/NIT/VIT/BITS robotics labs. If you're prototyping an industrial handler for delicate assembly lines, this kit accelerates your development cycle.
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 chat with the AI companion, which has been trained on the exact wiring and code for this kit. For human help, reach out on WhatsApp — our Bengaluru team responds within a few hours.
Do I need to source galinstan separately?
Yes, galinstan is not included due to shipping regulations. The kit provides PTFE tubing and detailed guidance on where to purchase it from verified Indian chemical suppliers, and the AI companion walks you through safe filling procedures.
What kind of silicone fingers are used?
You will fabricate them yourself using platinum-cure silicone (available at local dental supply stores) and 3D-printed molds. STL files and step-by-step molding instructions are included in the build guide; no prior soft-lithography experience is needed.
Is calibration required for the pressure sensors?
Yes, the MPX5010 sensors need an initial zero-point calibration. The code library provides an auto‑calibration routine that runs during the first power‑up, storing offsets in EEPROM. The AI companion also explains manual calibration if you prefer.
Industrial Automation — Galinstan channels in silicone fingers controlled by syringe pumps change stiffness for adaptable grasping.
