2.0 Questions

2.1 What will it do?

I think pan and tilt platform is very important for a developement of computer vision where a camera should follow a certain target. I am going to fabricate the machine in the fablab and program the algorith with it.

2.2 Who's done what beforehand?

I have found some people have done this beforehand and I take this as a reference and improve them.

For example. this guy has built a face tracking with a Pan/Tilt Servo Bracket and program it on C.

Face Tracking with a Pan/Tilt Servo Bracket

Furthermore, I like the way of this robotic arm platfrom that he built, the way it design is very elegant and functional.

BCN3D-Moveo

Basically, I am going to try to stand on the giant shoulder like Neil always said.

2.3. What will you design?

I have tried a lot to just 3d print the robotic arm from BCN3D yet 3D print but it does not beneficial regarding the timing process. It takes ages to produce a big part. Therefore I am going to design which has less 3D print part and try to use other subtractive fabrication.

2.4 What materials and components will be used?

18 mm Plywood

3 x Nema 17 stepper motor

3 x Pololu A4988 stepper motor driver

1 x GT2 300 mm pulley

1 x GT2 200 mm pulley

3 x GT2 20 teeth gear

3 x GT2 60T 8mm gear

Modified Satshakit grbl

9 mm thickness POM

ABS for 3d printer

M3 nuts and screws

M5 nuts and screws

M3 Threaded Nuts Insert

a camera

8mm rod with h6 tolerance

etc

2.5 Where will come from?

The local material shop

2.6 How much will they cost?

Less than 100 Euro for the material without the camera.

2.7 What parts and systems will be made?

The structure, mechanical parts and most of the electronics.

2.8 What processes will be used?

CNC machining for milling the PCB and cut the plywood, 3d printer for some difficult parts by machining subtractively.

2.9 What tasks need to be completed?

I need to finish the PCB and write a new algorithm and then I could add a remote to my robot.

2.10 What questions need to be answered?

Is the algorithm sufficient enough to track a certain target?

Does the structure easy to be adjusted with the timing belt?

Is the platform rubost?

2.11 What is the schedule?

I have tried to finish my final project since the begining of fabAcademy and now I would like to make a good board that can easy to connected to another modules and motor driver and upgrade the software algorithm to track a target in a very fast movement.

2.10 How will it be evaluated?

Does it follow the target?
