As usual I’m not the first one which build is own robot/drone/vehicle, and I’m very enthusiastic guy and I started with out a good project.
So lets to learn from the beginning, and mean while I’ll write the project, for a further use.
Here I’m going to put the main points.
What I want to do ?
This is the main question, and must be solved before to start anything.
I want to build a platform to study and develop a device, which will be able to move, add a computer embedded for computer vision.
Should be like a toy but following the next premise , keep as simple as possible
For the next projects I’ll do more interesting things, but for learn I need the simple model.
.- Which parts would have my robot/drone ??
- Chassis, structure
- Motors / servos
- Embedded computer
- Remote control
All this elements should be affect to the final result, and all of them are interrelated
1º .- Chassis, structure
The chassis is were I’m going to put every thing. Quite simple, no ?
Which is the size of everything ? and the weight ?
.- Batteries :
4 x AA (for arduino, and may be for the cubieboard) 55x60x20mm (100 gr)
2 x 18650 ( for motors and servos) 75x45x25mm (100 gr)
Here it’s necessary to know which sensor will be used, by the moment, 4 Infrared sensor for distance.
I’ll use two small protoboards 2 x (45×35)
Motor shield 70x55x15 (25 gr)
Arduino UNO 75 x 55 x 15mm 27 gr
1.2 Build or buy ??
I’ve already tried to build one, and I spend a lot of time, and money.
Is the time to try something al ready done
Length: 210 mm
Height : 66 mm
Width: 202 mm
Motor :3 v
Torque: 800 g/cm
Weight : 860 gr
Inside this structure I’ll put the batteries, and over may be the arduino and cubieboard,
I think it will be enough for my first project
So the elements by the moment are this
Weight 1370 g
Consuption 2732 mA at max Power
This is a small draft about the design, but I want to maintain as simple as possible.
