I’m launching a new robotics venture and need a batch of 20–22 reliable actuators for our first humanoid prototype. High torque is my top priority, so units that can consistently deliver around 30–40 Nm without excessive heat during 3–4 hour test runs are ideal. QDD-style or other proven high-torque robotic actuators—new or second-hand—are welcome as long as they are fully functional and already bench-tested. Here’s what I need from you: • A brief spec sheet or datasheet link for each proposed actuator (model, torque, voltage, weight, interface). • Clear photos or a short video showing the units powered on and rotating under load. • Confirmation of current condition, prior usage (if any), and test results—especially thermal performance. • Your pricing for the full lot (target budget is roughly ₹30,000 for all units) and estimated shipping timeline; I’d like them on hand as soon as possible. The actuators will drive limb and joint modules during continuous motion trials, so smooth operation and minimal backlash matter. If your models sit a bit above or below the exact torque range but have proven durability, feel free to propose them—stability and reliability can offset slight spec variations. Send your offer and supporting details, and I’ll get in touch quickly to finalize.
