Electric Office Chair DIY

You can build an electric office chair using a six-wheeled robot chassis and a regular office chair, as demonstrated by the 'e - Chair' project. Here are the details:

Hardware Assembly

• Minimalist Assembly Method: The 'e - Chair' project adopts a minimalist hardware assembly approach. Simply use binding wires to fix a regular office chair onto a six-wheeled robot chassis. This assembly method is relatively simple and does not require complex machining or professional welding operations, reducing the difficulty and cost of production. For those with some hands-on skills, following this method allows for relatively easy initial hardware assembly, combining the office chair and the robot chassis to form a basic electric office chair frame.
• Component Compatibility: A six-wheeled robot chassis usually has a certain load-bearing capacity and stability, enabling it to accommodate the weight and structure of a regular office chair. Moreover, the design of its wheels provides good mobility, allowing for smooth movement on both flat indoor surfaces and slightly uneven ground, meeting the mobility needs in daily office scenarios.

Control System

• Programming for Remote Control Driving: Through programming, you can achieve a remote-control driving experience for the electric office chair. With just a laptop and a gamepad, you can control the electric office chair. Programmers can write corresponding control programs based on the motor characteristics of the chassis and control requirements, linking the signals from the gamepad to the rotation of the chassis motors. For example, by operating the gamepad's forward, backward, left, and right buttons, you can control the forward and reverse rotation and speed of the chassis motors, enabling the electric office chair to move forward, backward, and turn, providing users with a convenient control experience.
• Scalability: This programming-based control method offers good scalability. In addition to the basic remote-control driving function, more features can be added as needed, such as automatic obstacle avoidance and speed adjustment modes. By installing appropriate sensors, such as ultrasonic sensors and infrared sensors, and feeding the sensor data back into the control program, the automatic obstacle avoidance function of the electric office chair can be realized, enhancing safety and convenience during use.

Battery Life

• Super Long Battery Life: The electric office chair in the 'e - Chair' project boasts super long battery life. This is attributed to reasonable battery selection and power management system design. When choosing a battery, you can select a high-capacity, stable-performance battery, such as a lithium battery, based on the usage requirements of the electric office chair and the power of the chassis motor. At the same time, by optimizing the power management system, rationally allocating the battery's power, and reducing the motor's energy consumption, the battery's usage time can be extended, reducing the hassle of frequent charging.
