Collaborative Dual Arm Assembly Robot
Automate Small-Part Assembly with a Collaborative Dual-Arm Robot Powered by 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.
Build a miniature industrial assembly cell that picks, places, and snaps parts together. Two 4DOF arms run synchronised G-code paths, mimicking the collaborative robots found in electronics manufacturing. This is a full-system integration project for experienced makers ready to explore real‑time multi‑servo coordination.
What You’ll Build
A dual‑arm workcell where eight high‑torque servos move components from a feeder to an assembly jig, then execute insertion or stacking sequences. The system displays live arm positions on an OLED and accepts G‑code commands through the Arduino Mega’s USB port, letting you design, simulate, and refine custom pick‑and‑place routines.
What You’ll Learn
- Generate and parse G‑code for multi‑axis servo trajectories
- Calibrate PCA9685 servo drivers for 8-channel synchronised motion
- Implement dual‑arm collision‑avoidance and cooperative task logic
- Design an assembly flow: feed, align, insert, and verify with sensor feedback

Who This Kit Is For
Advanced makers, B.Tech/M.Tech students in mechatronics and robotics, and industrial automation trainees who have already built single‑arm robots. Ideal for Smart India Hackathon hardware projects, IIT/NIT/VIT/BITS final‑year robotics labs, and ATL Tinkering Lab mentors who need a capstone dual‑arm system.
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 on the box to open your AI build companion, which understands every step of dual‑arm calibration and G‑code implementation. If something still isn’t clear, message us on WhatsApp — a human from the Compoden team responds within 24 hours.
Is prior G-code experience required?
Not mandatory, but you should be comfortable with Arduino programming and basic servo control. The AI companion provides G‑code syntax guides and sample routines to get both arms moving together quickly.
Can I program the robot using Python or block-based tools instead of G-code?
This kit is designed around G‑code, the standard for CNC and industrial robots. You can, however, convert Python‑generated coordinate arrays into G‑code using a simple script — the AI companion covers this bridge approach.
How precise are the arms for assembling components smaller than 5 mm?
MG996R servos offer positional repeatability around 0.5–1 mm. With proper mechanical calibration and spring‑loaded end effectors, the system reliably inserts SMD‑sized parts into jigs. Large‑scale production‑grade precision isn’t expected, but it’s excellent for learning industrial coordination.
Two 4DOF arms synchronised to cooperatively pick and assemble small parts. G-code programmed paths.
