ESTUN ER3-500S
by ESTUN Robotics
$6,000 - $10,000
The ESTUN ER3-500S is a cost-effective SCARA robot from China's largest listed robot manufacturer. At $6,000–$10,000, it costs 60-70% less than equivalent Epson or Yamaha SCARA robots while delivering ±0.015mm repeatability suitable for most electronics assembly and packaging applications. The lightweight 25kg design allows desktop or ceiling mounting for flexible deployment. ESTUN's vertically integrated manufacturing — from servo motors to controllers to the robot itself — enables aggressive pricing without sacrificing reliability. The ER3 is widely deployed in China's electronics manufacturing clusters (Shenzhen, Suzhou, Dongguan) for component insertion, testing, and packaging tasks.
