SDUCX – Raspberry Pi Robot

_Redstone_c_

This is the assignment for the 2021 Shandong University Future Science Camp (Summer) - Artificial Intelligence and Invention Creation Future Science Camp So just take a look

Basic Information

  • Name: Remote Intelligent Room Patrol Alarm Robot

Solve the problem of long-term unoccupied homes/rooms, but there are equipment operations or other needs that require remote monitoring. It can conveniently remotely monitor the home environment and monitor the operating status of the equipment. It has good mobility and flexibility and can adapt to different room environments.

Innovation

Apparently JD sells it

  1. Combining remote control cars and sensors constitutes a new product with remote monitoring functions.
  2. This project changed the dimensional parameters in the product and improved its performance.
  3. Applying network remote control technology to the field of remote control cars creatively solves the problem of remote control distance limitation.

market expectation

The market prospects are outrageous

As a low-cost solution, it can solve the need for flexible monitoring in the home. The beneficiaries are people who are away from home for a long time but have equipment running 7/24 at home and need unattended and remote monitoring of equipment operation.
As a low-cost solution, mainly for home use, the price is 1999 and the profit is 500.

Profit ratio (percentage) over time (days):
