# 11. Applications and Implications¶

### what will it do?¶

• It is an robotic arm that can determine points in three-dimensional space in order to convert these points into a three-dimensional model I will have to take some measurments which will be automatically taken by my robotic arm this is can be done when I have potintiometers in my arm then using forward kinimatics calculation I can determine my 3d position the x position and y position and z position this can be possible if I used four potitiometers.

### What will you design?¶

• I will be designing in Fusion 360 for the arm that form the hands using acrylic with laser machine or cnc machine cutting then I will add a variable resistance in the joints that I will connect them to the circuit that I made in the week (9) then I will decorate it with stickers

### what materials and components will be used?¶

• (4) variable resistance
• Wires
• Microcontroller
• Acyrilc sheet 30x60 cm
• Lap top
• power supply
• Screws
• Servo motor
• Pla filmant
• Swich

• FabLab Store
• Local shops

### how much will they cost?¶

• (4) variable resistance: 8.000 BD
• Wires: 2.000 BD
• Microcontroller: 6.000 BD
• Acyrilc sheet (thickness:10mm) 30x60 cm: 7.000 BD
• power supply: 5.000 BD
• Screws: 4.000 BD
• (4)Servo motor: 14.000 BD
• Pla filmant: 5.000 BD
• Swich: 3.000 BD

### what parts and systems will be made?¶

• Electrical circuit with eagle and easy EDA
• Mechanical hand with fusion360
• Processing unit with grasshopper

### what processes will be used?¶

• Cnc
• 3d printer
• lesr cutter
• milling machine
• Vynil cutter

### what questions need to be answered?¶

• Solve equations
• Programming
• The Programs used
• Design

### how will it be evaluated?¶

• It will be evaluated if the point in space location match “equal” the measured one using the robot potentiometers

### Plan

• Do more research on “forward kinimatics” (Apr 01: applications and implications)
• Try to implement the math behind it “using grasshopper”(Apr 22: interface and application programming)
• make my oun PCB to input and output data (Mar 25: input devices) (Mar 04: electronics design)
• fabricate the arms of the robot(Jun 17- project presentations )
• Put all parts together(Jun 17- project presentations )
• Test the accuracy(Apr 22: interface and application programming)
• Modify and correct any error in the readings(Apr 22: interface and application programming)
• After building the input arm “potintiometer” I will build the output arm “servo motor” (Apr 15: output devices)
