Robotic Crane using PIC16f or 8051
May 12, 2009
hey! i'm planning to make a robotic crane.and i reallly need help.
the basic idea is to build a robot WITH PIC16F877A (OR 8051) which carries magnetic loads(it has other auxilliary functions as well)
we had actually planned to triagulate the position of the object by sending out some kind of signal in a small scale radius around the robot,detect the object and carry it to the the coordinates of the point entered by the user where the object is to be unloaded.but due to the complexity of the procedure(and we were unaware of what technique to use?) we decided we'll predefine a path the robot will follow. ie the obstacles will be kept on one side of the path and it will place it at the other end of the closed path.
we plan to use a electromagnet to attach the object whose current and hence the magnetic strength will be software controlled.
weight measurement and weight overload indicator also is planned to be in corporated.
wheel movement and pulley for the weight requires motors. and we were plannin to use a stepper motor for the wheel direction.We also plan to use sensors (infrared proximity) for the obstacle detection and a feedback control for whether the object has been lifted or not has also to be included.
NOW I REALLY NEED HELP TO DECIDE ON WHAT MOTORS,sensors TO USE AND WHAT ARE THE REAL TIME ERRORS THAT CAN COME AND ALSO TO HOW EXACTLY GO ABOUT THE WHOLE BUILDING OF THE ROBOT FROM SCRATCH.
REALLY REALLY looking forward for help.thanks so much
