OpenManipulator-P机械臂入门教程-硬件介绍
说明
- 介绍OpenMANIPULATOR-P (RM-P60-RNH)机械臂的硬件组成以及相关的硬件参数
概述
OpenMANIPULATOR-P机械臂是一个完全开源的机器人操作平台
OpenMANIPULATOR-P机械臂基于ROS和OpenSource。使用者同时可以使用MoveIt!来控制它。
OpenMANIPULATOR-P机械臂同时支持Gazebo进行仿真
在ROS环境中,OpenMANIPULATOR-P机械臂支持在U2D2+U2D2电源转接板或者OpenCM板上使用;若在嵌入式系统上运行时,请准备OpenCM板。在这两种情况下,都要使用24V电源给DYNAMIXEL舵机供电。
