bluetooth transporter

A Bluetooth transport car based on ESP32. Reproduction of Station B's "Blank Innovation Studio"
premise description: He has made upgrades and transformations in his project. The specific transformations are as follows: he wants to add a camera, design a large body (used to hold various things), and add ultrasound Obstacle avoidance module can realize automatic transportation by slightly modifying the program. Modify the APP that controls the car (the original APP actually has ads. As someone who doesn’t like to watch ads, how could I allow ads to exist, so I made my own one without ads, hahahaha. Don’t worry, the APP will be optimized in the future. ) However, the current version 1.0 of the transport trolley only allows the modification of APP (because it really cannot accept advertisements). The APPs with advertisements and without advertisements are placed in the URL at the bottom. You will know by comparing them. Later, I will slowly learn 3D modeling and Android (Android) and add various modules to achieve more functions.
Price: Because it uses 32, it is not very cheap, but it is not very expensive either
. 1. The main control ESP32 is 11.5 yuan. Link (https://m.tb.cn/h.fErfnpE?sm=50d5ef?tk=7GQm2LRXWav)
2. Universal wheels: 4 wheels for 23 yuan (very cheap, okay) buy No. 3, which is the largest 68mm , very scalable. Link (https://m.tb.cn/h.fwKnf2X?sm=e6c907?tk=nZCg2LRd1pA)
3. Geared motor: 5 for only 11 yuan, keep one extra as a spare, it’s really delicious, some Xixi, link (https ://mobile.yangkeduo.com/goods1.html?goods_id=306345357662&page_from=101&pxq_secret_key=VDQEX PKH4FQFZZASQORG4O3UFHOBYGEXA6HMA6QKQHMMZYPLGCPA&share_uin=3HT3LPSFHMY5BPOIY3EXAOYPUY_GEXDA&re fer_share_id=977b1b1242e741d9b9c4589196b6095c&refer_share_uid=8811505793335&refer_share_uin=3HT3LPSFHMY5BPOIY3EXAOYPUY_GEXDA&refer_share_channel=copy_link&refer_share_form=text) Xixi link is relatively long, no problem.
4. Novices on various components recommend placing orders immediately. Needless to say, veterans, there is a table below: it only costs about more than 30 yuan.
5. 3D printing only costs 5 or 6 yuan. You can choose Taobao (compare three stores) or choose Lichuang 3D Monkey Printing,
 
so the total cost is about 60 yuan.
There is also a coupling (which is used to connect the wheel and the reduction motor). , see my website below for details, (detailed introduction is in the website) Just solve the problem yourself!
