After more than ten days of crazy Taobao, assembly, debugging, disassembly, recall, then debugging, my WiFi Robot is finally available! ! Tears! The following is simple to write and write the production process, and you will leave your own archive.
The program is the WiFi trolley plan, the driver board and control procedure is ready ... but now I have found that it is convenient for eating ready, but the expansion function is less pitiful. The next step is planning to buy a block Arduino board himself to study the reassemble truck, write the program yourself.
WiFi Robot, as the name refers to the robot controlled by WiFi wireless network, compared to ordinary remote control robots, it is that the remote control signal coverage can be very wide, or it can be remotely remotely controlled by the Internet, so that you can derive it Many new applications such as video surveillance, etc. Because it is a newbie beginner, the shape and function of the robot is also rough, the master saw not joke ~

DuPont line screw nuts, etc.
Total: 673.3 yuan
Since it is the first time the robot is made, the tool is basically no, and the light to buy electric iron hot melt adhesive gun electric drill has spent a lot of money. Plus a mess, a total of 1200+. The living expenses for more than a month are not ...
2. Everyone appreciates my work environment
The bedroom conditions are relatively simple ... Computer screen is the robot control interface
I have been using a carton to make a frame using a carton before buying a jacket and electric diamond. Although the carton is easy to process, it is too soft and the car is often biased. Moreover, due to the unsuitable distance of the route, the turret is too large after the increase in the load, and the trolley is basically turned.
I forgot to take pictures before I was demolished, I had to take it together. It can also be seen that the shadow of the original car.
Acrylic boards are very cheap, easy to process, can be processed from the finished board. However, the disadvantage is that it is not as good as aluminum plates and pulling the wind, and cracks can be easily occurred. If you use aluminum to make a frame, you can consider using aluminum boxes or corner aluminum. It is also a very good frame after simple processing.
3. Formal start!
First install the motor bracket on the chassis. In the appropriate place, punch and install the motor bracket. Note that the aperture should not be too small, otherwise the forcibly screw can cause acrylic cracking. In addition, the positioning of the cone will not be paired with the positioning of the cone.
If it is a homemade frame, take a good wheel. I did four-wheel drive, and the left and right turns should be reached on both sides, and the pulling is too wide to cause too much turning resistance.
The drive plate is fixed on the front. It can be considered to use the copper column to high the plates and easy to pass.
Install the stepper motor and weld the control line. Take the tab in the tin before the soldering, which will be more convenient. In addition, the servo power supply portion of the driver plate is a piece of L7805 ($ 0.1250). It is fever when working, and I use the screw to help heat dissipation on the aluminum motor bracket. The effect of the metal body is of course better.
The 5110 screen is fixed to the board. In order to facilitate view, Take DuPont line.
Secure the battery on the back of the second floor. Originally wanted to make a drawer that was easy to take out, did not find a suitable material material, and finally used tape and rubber bands to fix the power supply of the ship type switch to control the drive plate on the side of the vehicle body.
The head is installing the ultrasonic sensor. Take the hot melt adhesive, the effect is not very good, I plan to change it. Note that it is best not to reach out of the body, which is not damaged when the train is hit.
Install the router board on the second floor. DB120 This route is actually a customized routing of telecommunications, with ADSL function, so the volume is relatively large, and the width is exceeded the board. No way, two holes were drilled on the board without the wiring, and the copper column was fixed on the board. After installation, I found that the original routing indicator is just as a car light, it feels good.
The third layer is installed 2 degrees of freedom camera. The disadvantage of this installation is obvious, the helm, battery, etc., more components, are concentrated in the rear of the vehicle, and it is easy to reach the car. However, the reason for space and wire length is not very good in other places, I have to balance the center of gravity in front of the front of the car.
I used the camera housing too ordered, so I used the circuit board nude, so it must be fixed with hot melt adhesive, avoiding the camera steering timeline.
Secure 5110 screen on the frame to facilitate viewing of running information. The current program enables the function of viewing the distance between the temperature and the front obstacle.
Plug the camera on the USB port of the router, the servo control line is inserted on the drive board, and the route is connected to the drive board. The trolley has been initially set.
Fixed routing antenna. The DB120 comes with the antenna too pocket, and the estimated signal will not go. The next step is planning to buy a radar type orientation antenna to install it, hare, haha. However, it seems that the remote control of the trolley is not suitable for the antenna, so it can only be yy.
4. Finish! !
The car is assembled! ! Still better, haha.
From this perspective, it is quite a little machine "person".
Next, the router brushed into OpenWRT and installed the WiFirobot program, which is set to the Client mode to access the level of routes. There is a detailed tutorial in this part of the IGEE forum, it will not be described.
This is the control interface of the train ~
Because the work of programming and circuit design is not used, this car is still faster, and it has been used for more than a week, including waiting for express delivery.
In fact, the main role of this car is also a funny WiFi Robot, which is a very cool WiFi Robot, which is a true cool thing, isn't it?
