Plan for my recycling robot By: Linda Bouguila

Gather the materials (1) The materials needed to make this product are: 1.Main parts : Body made from resistant material (skeleton), a mechanical filter, an analyzing box, 5 bags and drawers, 6 tubes: 5 tubes to connect the analyzing box to all the bags and 1 tube to connect the filter to the general waste bag. 2.Sensors: Eddy current separator, near infrared sensor.

Gather the materials (2) 3.Actuators: a ‘hand’ that could grab things from the size of a tennis ball to the size of a newspaper, six traps: the first one will be below the analyzing box and the 5 other traps will be for each bag. Each trap will give a way for the analyzed item through its correspondent bag.

Building (1) 1.First, place the filter inside the skeleton, in the upper part. 2.Place the 1 st tube in order to catch all the things that will pass through the filter and connect it to the general waste bag. 3.Place the analyzing box in the center part of the skeleton.

Building (1) 3. Place the analyzing box’s trap (trap AB) below the analyzing box. Place the five remaining traps below the first trap. 4.Place the tubes between the traps and the bags; the upper side of the tube underneath the correspondent trap, and its lower side to its relevant bag. 5.Connect the five traps to the CPU (brain). 6.Place the Eddy current separator in the analyzing box and connect it to the CPU.

Building (2) 7.Place the Near infrared sensor in the analyzing box and connect it to the CPU.

Instructions Add instructions (CPU programming instructions): Step 1: Grab an item from the filter with the ‘hand’, Step 2: Send the item to the analyzing box, Step 3: Activate the Eddy current separator, Step 4: Check the test’s result, Step 4-a): If the test is successful, Open trap M, Then open trap AB, Go to Step 1.

Instructions Step 4-b): If the test is unsuccessful, then go to step 5. Step 5: Activate the Near infrared sensor. Step 6: Check the test’s result. If plastic has been identified, go to step 6-a). If paper has been identified, go to step 6-b). If glass has been identified, go to step 6-c). Otherwise, go to step 6-d). Step 6-a): Open trap P1, Then open trap AB, Go to Step 1.

Instructions Step 6-b): Open trap P2, Then open trap AB, Go to Step 1. Step 6-c): Open trap G, Then open trap AB, Go to Step 1. Step 6-d): Open trap GW, Then open trap AB, Go to Step 1.
