STS3215
A standard serial bus servo commonly used in open-source robotic arm projects, featuring position feedback capability and widely adopted in low-cost robotics platforms such as LeRobot.
Timeline (last 90 days)
SO-101 (SO-ARM101) is an entry-level 6-degree-of-freedom 3D-printed robotic arm in the LeRobot ecosystem, with a total cost on the order of about 100-200 USD (excluding the 3D printer), driven by standard servos (such as the STS3215 series).
In the parametric design, the relative positions of the servo slots and screw holes are locked by program logic, always aligned to the mounting positions required by the STS3215 servo.
Lamp is an open-source desktop robot project equipped with a 5-DOF robotic arm, running STS3215 bus servos, powered by a single 12V cable, and using a USB DAC to eliminate ground noise.
The Feetech STS3215 is a serial bus servo that uses a single-wire half-duplex TTL serial communication protocol and supports multi-dimensional feedback including position, speed, and current.
The STS3215 has a position resolution of 4096 steps (12-bit) and a torque of approximately 17 kg·cm.
Inexpensive servos typically use plastic gear trains with backlash of up to 1°–3°, whereas high-end bus servos use metal gears and can keep backlash within 0.5°.
STS3215是飞特（Feetech）公司生产的智能串行总线舵机，采用TTL半双工通信协议，输出扭矩约17kg·cm，工作电压6-12.6V，内置磁编码器提供12位（4096级）角度分辨率，约0.088°角度精度
全新的STS3215舵机出厂时ID默认都是1，开发者需要逐个为每个舵机分配唯一的ID并进行归零校准
全新的STS3215舵机出厂时ID默认都是1，需要逐个分配唯一ID并进行归零校准，归零数据存储在舵机的EEPROM中，重新刷写固件也能保留
机械臂采用5个STS3215总线舵机，通过菊花链方式连接在同一条TTL总线上，再经由USB适配器接入主控板，整条机械臂只需一根线缆且无需额外驱动板
