OBJECTIVE- we have designed manual controlled garbage picking robot which can traverse in any plane and pick and place objects accordingly.. i controlled my robot using 2 different method 1-DPDT Switch based
2- Bluetooth controlled .

COMPONENTS: DPDT CONTROLLING:-
4 DC 12 volt motor--100rpm ;
2 DC 12 volt motor--3.5rpm ;
1 DC 12 volt motor--60rpm.
4 whells.
1 Rack and 1 Pinion.
4 DPDT switches
4 inch long Rack angle
Connecting wire
Some jumper wire.
Hadder pins.
1- 12 volt adaptor. FOR MOBILE CONTROLLING:-
--->Above components and--
1 Aurduino.
4 Motor driver [L293D].
1 Bluetooth module[ ].
9 volt normal battery.
Plastic sheet ;soldering iron& wire hook wire.
HARDWARE DESCRIPTION:-
1-First of all cut a ply board/acrylic sheet in C shape and T shape as which is for dynamic structure.
2-DC MOTOR-A DC motor is any of a class of rotary electrical machines that converts direct mechanism, either electromechanical or electronic, to periodically change the direction of current flow in part of the motor .We required different rpm of 12 volt current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal of 12 volt motor as in fig.

3-WHEELS:-

4-RACK AND PINION:- rack and pinion is a type of linear actuator that comprises a pair of gears which convert rotational motion into linear motion. A circular gear called "the pinion" engages teeth on a linear "gear" bar called "the rack"; rotational motion applied to the pinion causes the rack to move relative to the pinion, thereby translating the rotational motion of the pinion into linear motion.
5- DPDT SWITCH:-A Double Pole Single Throw (DPST) switch is a switch that has 2 inputs and 2 outputs; each input has 1 corresponding output.Each of the terminals of a double pole single switch can either be in the on position (closed) or in the off position (open).A Double Pole Single Switch has a lot of versatility being that it accepts 2 inputs, which makes it then be able to drive 2 different outputs in a circuit. What it drives depends on the circuit design and what the circuit is intended to do. But DPST have enormous applications in circuits.
6-RACK ANGLE:-It helps in the sliding the gripper which is made by the rack and pinion .Seen in the figure.

7-HADDLE PIN:-Center Headers" are the pins that you will solder onto your PCB. Terminal Housings are the connector part that attach to the headers. Last but not least are the crimp pins that make the electrical connection. The metal parts are available in tin or gold plating
8-ADAPTER:-Power supplies allow you to connect your project to the mains and converts AC voltage (used for common household appliances) to DC (used in robotics). You'll find a range of simple fixed voltage wall adapters or variable output power supplies .
9-ARDUINO:-Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical and digital world.
10-MOTOR DRIVER:-From microcontroller we can not connect a motor directly because microcontroller can not give sufficient current to drive the DC motors. Motor driver is a current enhancing device, it can also be act as Switching Device. Thus we insert motor driver in between motor and microcontroller. Motor driver take the input signals from microcontroller and generate corresponding output for motor.
11-BLUETOOTH MODULE:HC‐05 module is an easy to use Bluetooth SPP (Serial Port Protocol) module,designed for transparent wireless serial connection setup.The HC-05 Bluetooth Module can be used in a Master or Slave configuration, making it a great solution for wireless communication.
12-BATTERY:-The nine-volt battery, or 9-volt battery, is a common size of battery that was introduced for the early transistor radios. It has a rectangular prism shape with rounded edges and a polarized snap connector at the top. This type is commonly used in walkie-talkies, clocks and smoke detectors.
