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.

who has done what beforehand?

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

where will they come from?

  • 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)
