Reclaiming India's Motion-Control Sovereignty

Overcoming foreign supply-chain reliance with 100% Indian IP, designed to directly replace imported modules like the Maxon EPOS4 series.

Cost Efficiency

Achieve up to 68% cost savings compared to equivalent foreign modules. Targeted at ₹12,000–₹21,150 per unit at scale.

Strategic Autonomy

Built on 100% Indian IP. Fully ITAR-free compliance eliminates export control risks and secures defense supply chains.

Reduced Lead Time

Accelerate project timelines with delivery lead times reduced to 8–12 weeks, mitigating the 18–24 week waits of imports.

Built to Military Standards

The EPSO4 architecture provides deterministic, real-time performance tailored for the most demanding environments.

3-Tier Control Stack

Current (≤ 50µs), Velocity (≤ 1ms), Position (≤ 5ms) loops.

Cyber Hardened

Secure boot, RSA-2048/ECC-512, and ARM TrustZone.

Qualification Targets

MIL-STD-810H, MIL-STD-461G (EMI/EMC), BIS, DRDO.
