This kinds of stupid projects I often develop when I have nothing to do at my room. Well this bot resembles the lifters often used at places like dockyards,store rooms etc…but the problems with them are multiple controls .Apart from using that in industrial purpose these can also be implemented on robots meant for competitions for reduction of controls n time n for making them more efficient.
OPERATION
1.When the gripper is low below and when it holds an object the spdt switch in path no.2 gets connected(say it flows through that part of the ckt,glows the LED1,activates the relay 1 & relay4 representing s1 & s4 of the H-bridge).
Then the motor starts & it pulls the gripper arrangement upwards.
2. when it reaches the top, the carriage motor automatically stops as it pushes the switch2(push to off switch).
3. Now when we open up the gripper current starts flowing through path1 as that part of the spdt switch gets connected.(Now the current starts flowing, glows LED2,activates relays 2 & 3 representing s2 & s3 oh the H-bridge).
Then the carriage motor starts revolving in opposite direction n brings the gripper arrangement down below from where it started.
That’s it folks for now…. Waiting for ur comments.
