论文摘要
最近，沟通和机器人技术领域的发展取得了飞跃。此外，这两个学科的融合都为使人类的生活更轻松，更好地做出了巨大贡献。因此，在使用上述技术的同时，提出了一种设计和实施机械臂的设计和实施程序，即，提议的臂将通过与安装在机器人臂上的接收器相连的蜂窝设备进行操作。此外，在呼叫的持续时间内，如果从蜂窝设备按下任何键，则在接收器侧注意到按钥匙的指示器模糊不清。这种音调代表两个不同频率的叠加，并称为DTMF（双音多频）。此外，通过DTMF音调处理机械臂。同样，使用DTMF破译模块即MT8870，将接收器的获得的音调带入微控制器（ATMEGA16）中。此外，解密模块将DTMF信号放在其相应的两个位表示中，然后将匹配的数字传输到微控制器。对微控制器进行编程以根据解码值采取措施。此外，微控制器将控制信号转发到电动机驱动器单元，以向前/向后或多个方向路线移动手臂。最后，机械臂能够在通过GSM（全球移动通信系统）无线控制时拾取和放置对象。
In recent times, developments in field of communication and robotics has progressed with leaps and bounds. In addition, the blend of both disciplines has contributed heavily in making human life easier and better. So in this work while making use of both the aforementioned technologies, a procedure for design and implementation of a mobile operated mechanical arm is proposed, that is, the proposed arm will be operated via a cellular device that connects with the receiver mounted on the robotic arm. Moreover, over the duration of a call, if any key is pressed from the cellular device than an indicator indistinct to the key pressed is noticed at the receiver side. This tone represents superimposition of two distinct frequencies and referred to as DTMF (dual tone multi-frequency). Further, the mechanical arm is handled via the DTMF tone. Also, the acquired tone at the receiver is taken into a micro-controller (ATMEGA16) using the DTMF decipher module i.e. MT8870. Further, the decipher module unwinds the DTMF signal into its corresponding two bit representation and then the matched number is transmitted to the micro-controller. The micro-controller is programmed to take an action based on the decoded value. Further, the micro-controller forwards control signals to the motor driver unit to move the arm in forward/backward or multi-directional course. Lastly, the mechanical arm is capable of picking and placing objects while being controlled wirelessly over GSM (Global System for Mobile Communications).
