1、The structure is simplified, the weight of the forearm is reduced, and the installation is easier. 2、All bracket accessories are made of 2mm thick aluminum plate, which effectively improves the stability of the manipulator. 3、Imported cup‑type bearings are used at the steering joints, which not only makes the steering more flexible, but also makes the steering gear turn at the same center. 4、The chassis is in the form of a disc, which makes the manipulator rotate more flexibly and smoothly. 5、Can be widely used in college teaching, DIY production and maker education. 4 x Multi-Function Bracket2 x Long U-Shaped Bracket2 x L-Shaped Bracket 1 x Different U-Shaped Bracket3 x Extension Cord1 x Cable Tie2 x Beam1 x Flange Rod 1 x Manipulator97 x Screw55 x Nut6 x Metal Rudder Wheel 3 x Flange Cup Bearing1 x Wrench10 x Cable Tie4 x MG996 Analog Servo 2 x YF-6125MG Digital Servo  Item Type: Mechanical Arm SetMaterial: Aluminum, other metalsModel: 4264Grab Weight: Approx. 400 g / 14.1 ozTravel Range: Approx. 43cm / 16.9inClamping Range: Approx. 5 ~ 55mm / 0.2 ~ 2.2inPurpose: Multi-degree-of-freedom demonstration platform Servo Model YF-6125MG Digital Servo MG996R Analog Servo Operating Voltage 4.8V－ 7.2V No-Load Current 100mA Steering Gear Torsion 15kg.cm 10kg.cm Limit Angle 180°/270° 180° Wire Length Approx. 30cm / 11.8in Gear Material Metal gear Dead Time 3uS 5uS Servo Performance The steering gear has a small virtual position and accurate centering General How to Use: 1.
