FEETECH STS3250 Stall Torque & Repeatability Test Measured: 25 kg·cm sustained, up to 48 kg·cm peak (datasheet: 50 kg·cm). Repeatability: ±0.02 mm at 95 mm arm. Excellent precision despite protection limits. #Feetech #STS3250 #ServoTest #Robotics

Load test of the Feetech STS3250 servo: • 2 kg load on 100 mm arm — near operating limit • Higher acceleration reduced lifting capability • Temperature rose from 40 °C to 70 °C in 8 minutes #Robotics #ServoMotor #Engineering #Testing

Topology optimization by Robonine reduced displacement in key manipulator parts: - Aluminum bracket – 0.16 mm - Steel bracket – 1.05 → 0.63 mm - Clamp – 0.14 mm Smarter geometry, lighter design, stronger results. #Robonine #Robotics #Optimization #FEA #Engineering

Measured Feetech STS3250 speed vs spec: • Datasheet: 0.133 s/60° → ≈75 RPM • Encoder: 5,300 counts/s, 4,096 CPR → (5300 / 4096) × 60 = 77.6 RPM Only ~3% difference — right on spec! #servo #robotics #automation #engineering #Feetech #mechatronics

We've created a HEX mesh and started analyzing the model's stiffness. Our goal is to achieve a maximum displacement of 0.3 mm under full load! #Engineering #FiniteElementAnalysis #FEM #MechanicalDesign #Innovation

Backlash test - Feetech STS3215 Result: 0.87° angular backlash Tested with 86mm lever, dial indicator, and rubber band creating ~30g controlled tension. Linear displacement 1.3mm converts to 0.0151 rad. #Feetech #STS3215 #Robotics #ServoMotor #Backlash #Precision #SmartServo

With @robo_nine team we’re preparing an in-depth review of the Feetech STS-3250 servo motor — exploring its performance, features, and potential for robotics and automation projects. #Feetech #STS3250 #ServoMotor #Robotics #Automation #Engineering #TechReview #Innovation

Testing the new Feetech STS3250 coreless motor (50 kg·cm) after the STS3215 (30 kg·cm). Engineer’s first feedback: “Runs much smoother and quieter.” Promising results for robotics and motion control. #Feetech #CorelessMotor #ServoMotor #Robotics #Engineering

Our new Feetech STS3250 servos just arrived! Load and positioning accuracy tests coming soon — stay tuned 👀⚙️ #robotics #servo #engineering #Feetech #testing #automation

At Robonine, we use paired Feetech STS3215 servos in our robotic manipulators to eliminate backlash. By setting opposite neutral points, both servos stay in slight tension — keeping motion smooth and precise. #Robonine #Robotics #ServoControl #BacklashCompensation #FeetechST

Our engineering team has updated the connection design. We increased the folding angles of the joints to 270 degrees. The manipulator can now fold completely. #Engineering #DesignUpdate #Mechanical #Manipulator #Innovation

Feetech STS-3215 servos reached 21–27 kg·cm each (nominal 30). Dual setup delivered 42–46 kg·cm — ~30% loss from torsional flex & uneven load. Boosting rigidity improves torque efficiency. Protection settings = safety, not power. #Feetech #STS3215 #ServoTest #Robotics #TorqueLoss

Feetech STS-3215 static torque test: • 10 cm lever, 45° angle • Holds ≈ 3.5 kg static load • Overload protection cuts torque to ~20% under long heavy load • Timeout & torque limit adjustable in controller #Feetech #STS3215 #Servo #TorqueTest #Robotics

Feetech STS3215 servo test: ±0.01 mm deviation on a 10 cm arm → ≈0.0057° repeatability (≈20 arcsec). That’s ~15× finer than one encoder step (0.088°) and ~1 % of rated backlash. Excellent precision and stability for fine positioning tasks.

Test setup: 2 Feetech STS-3215 servos + 3D-printed PLA lever arms. Each applies small pre-tension on rope to reduce backlash. Demo shows improved stability & precision in robotics/motion systems/DIY. #Feetech #STS3215 #ServoTest #3DPrinting #Robotics

In Aug, our @robo_nine manipulator prototype was estimated at ~$1600/unit, $1000 in 100 pcs. Goal now: <$800 prototype, ~$600 small-series. How? Minus one 1 DOF (no forearm rotation) ~5× fewer parts Payload ↓ 3kg → 1.1kg #Robotics #Automation #Engineering #Manufacturing

We assembled a metal prototype of the 2nd joint for our robotic arm. It is driven by 4 Feetech STS-3215 servo drivers. Current tests focus on backlash compensation using a belt pre-tensioning mechanism. #Robotics #Engineering #Mechatronics
