Seventh day

We finally got our motor’s and ESC’s!

Every compenent was measured, to check that everything fits.

ESC’s have 8 wires, 2 for batteries, 3 for the motor, and 3 for the microcontroller. The PWM is generated in the arduino and goes to the ESC, wich lets the energy of the batteries go to the motor. As you vary PWM’s high time, you vary how much power goes to the motor.

We screwed the motors to the “x” part of the structure, it’s starting to look like a quadcopter! but don’t get to excited, there’s still a loooong way to go.

PCB board design has finished, the manufacturing process has started.

Here’s a good vid describing the process of manufacture:

Remember that we’re using Proteus (Ares) software to design our boards. However, you can use the one that suits you best.

Here you can see some pics:

We also started to work with an encoder, the idea is checking how fast motors go at different PWM outputs. For the moment, we are working with a regular DC motor (50 RPM at 12V)

Here are some pics (the arduino UNO and the potentiometer you see there weren’t being used):Image

Some wires and oscilloscope probes.

Another angle…

Well, that’s all for now, stay tuned and have a nice day.
