The main challenges of the project are: little knowledge (almost none) about the robot dynamics as none of the mass and link parameters given; joint flexibility and low frequency resonance caused by harmonic drive systems.
本项目的主要难点在于:因机器人杆件的质量、长度等参数未知导致难以得到机器人精确的动力学模型;由于使用谐波驱动器而引入的关节柔性以及低共振频率限制控制系统的带宽。
