Servos did not come our way(they were available online though,but that did not seem to be a feasible solution).We decided to patch it up using chinese gear motors and high precision potentiometers as the input device and also for the feedback mechanism(ours will be an automatic servomechanism feedback control system).
The links are ready.They are made of 5 mm thick aluminium rods about 6 1/2 inches long .Currently work is going on the assembling of the gear boxes and the links on the platform.
After the assembly part is over we will start working on the circuit.we will be using OP-AMPS for amplifying the input voltage signals that will then be fed to the potentiometers attached to the gear boxes and the resultant signals will hopefully move them.
The construction part though is not going too well ,had to make numerous changes midway and it is taking up too much time .We would have liked it had it been completed in 2-3 days time as a chunk of the time will have to be spent on the simulation part and to check whether everything is falling in place.
For the time being we are engaged in drilling holes into plastic cases and aluminium rods(I hate to say it but the construction part has been up to late a comedy of errors).Trying hard to complete as efficiently as we can.Seems like we need a lot of luck to finish the entire thing by the 5th of next month.The hardest part was the conceptualisation and the designing part, we thought,and that everything after that would turn out to be a cakewalk .It seems now that our plan backfired .
moral:NEVER GO FOR MANUFACTURING WITHOUT THE COMPLETE PLAN LAID OUT IN FRONT OF YOU
