Two-degree-of-freedom pan-tilt robot control platform

This work, titled "Two Degrees of Freedom Pan-Tilt Robot Control Platform", implements a complete pan-tilt robot control platform. The system uses motion sensors as control handles to control the movement of the robot, and cooperates with the OLED screen to display the system's Current status. Using the control handle, you can control the movement of the vertical axis servo through forward and backward movements, and control the movement of the horizontal axis servo through rotation operations, thereby realizing two degrees of freedom control of the robot.

Escorna CPU 2.12: An open source hardware project geared towards robotics and programming for kids.

The basic Escornabot can be programmed to perform a series of actions using the robot's buttons. From this point of view, imagination is the only limit on possibility.

NanoClon 0.01: used to assemble mClon type robots

This circuit has everything you need to assemble a mClon-style robot, without the need to find the missing Arduino circuit from RobotDyn used in the ShieldClon version.

Components can be SMD or THT, except the boost circuit/lithium battery charge controller is SMD, the 1206 and 0805 components are larger than the usual 0603 and 0402). You can choose not to solder the boost smd component and just solder the Bat-Vcc selector on the bottom to use the power bank.

posture correction robot

It's common for computer users to bend over in front of a screen, which can eventually lead to back problems. There are various gadgets on the market that solve this problem by constantly reminding users to sit up straight, but most of them are not fun. So I made a fun little tool for this problem.
