This Mobile Robotic Arm is our final year project which is still under construction.The Mechanical assembly is as seen in the image above.The main mechanical components are the different gears which are made up of brass .The gripper uses shape memory alloy(SMA) pistons from Mondotronics.The different kind of motors used are the 4 phase stepper motors for the links and 90 rpm servo motors for the differential system for the mobile base. The arm is fully computer controlled through the parallel port for wired transmission in case of short distances(10-15m)and through the serial port for wireless transmission for longer distance(in excess of 20m).The modulation technique used for wireless transmission is Amplitude Shift Keying.There is a decoding circuit for the expansion port for both the modules. The software has been written in Turbo C as well as VB6 .Two CCTV video cameras have been interfaced, the camara sends the image to the computer, the computer process the image in real time. The cost of this robot is around 1000USD My group comprises of two more people (Fareed & Saba). I am thankful to all those who have helped me especially Irfan sir Faruk sir & Zahir.
