01 — 项目详情
概况、物料清单与资料
项目概况
Berkeley Humanoid Lite(BHL)由 Koushil Sreenath 组推出,目标是让中等尺寸人形机器人变得“买得起、做得出”。它的核心是模块化的 3D 打印摆线减速执行器:电机、驱动板、轴承都是通用件,外壳和减速器用桌面打印机就能打印。
行走策略在仿真里用强化学习训练,可以零样本迁移到实机。硬件设计、嵌入式代码、训练和部署框架全部开源,还提供 VR 遥操作。

3D 打印与制造
- 官方推荐标准 PLA(如 Bambu PLA Basic);每个 6512 执行器约用 0.12 kg,5010 约 0.10 kg。
- 参数按 Bambu Lab X1C 调校,分“执行器外壳”和“执行器轴”两套配置;其余结构件可以更快打印,左右件沿 X 轴镜像各打一份。
- 输入轴里嵌黄铜六角柱、用 M3×55 贯穿螺丝防止层间开裂,躯干用铝型材。
- 切片好的 .3mf 在 Bambu MakerWorld(需登录下载)。
