[Mini intelligent obstacle avoidance mobile robot] Unboxing [Copy link]

 

 

Robots are very popular now, and they have been applied in many fields, such as automatic sweeping robots, automatic transport robots, etc. Robot technology is bound to be a major trend in the future. The smallest mobile robot on the market is as big as a notebook, because the laser radar needed for map building is at least as big as a mouse. I am very interested in this aspect, and I wonder if there is a very mini mobile robot that can be equipped with a miniature laser radar to achieve intelligent obstacle avoidance function on the desktop?

I also saw a new ST TOF sensor - vl53l5cx in the material list of Digi-Key Electronics Innovation Design Competition. It can be used to obtain 4*4 or 8*8 depth data, which happens to be able to realize a micro laser radar.

So I ordered 6 vl53l5cx within the budget, and added an ESP32-S3-DEVKITC small development board to achieve reading (cou) access (dan).

I received the express at the company that day and forgot to take photos in time, so I just unpacked it.

So there are only the following unboxing pictures.

First of all, the ESP32-S3-DEVKITC small development board. If I use it later, I will probably buy an ESP32-S3 module on TB, after all, it seems to be only more than 10 yuan.

Here is a detailed photo

The following is the new vl53l5cx from ST. I bought 6 of them at once. I originally wanted to make a 360-degree laser radar, but I'll see how it goes later.

After looking through the data sheet, it seems that the measurement depth and accuracy are average. However, it is enough to make a desktop mini car.

Here is a detailed picture of the front, and there is also a QR code

Back side solder pad

Well, that's all for this unboxing post. I will make a small development board later and run the data to see the effect.

VL53L5CX is still quite fun

Give the landlord a picture

I am also looking at this information, it is indeed a good long-distance measurement

Where is the VL53L5CX installed in the car?

Very good, looking forward to a follow-up detailed post , using it in the actual project

Most likely it is the front end, used to replace ultrasonic ranging

My understanding of the desktop mini cart is to place the VL53L5CX around the cart to prevent it from falling under the table.

The boss came directly with 6

Hexagons are more stable than quadrilaterals.

Have you run already?

The initial idea is to put it in the front, and if possible, you may stack several to increase the amount of data.

Hahaha If I have enough time, I plan to use SLAM, if not, I will just use it for obstacle avoidance

Haha, looking forward to your work!
