8 Input RCX Touch Sensor Mux
The RXMux is designed to facilitate the integration of multiple RCX-style sensors into a single NXT port. By allowing the connection of up to four analog sensors, it effectively expands the sensory capabilities of the NXT robotics platform. The RXMux operates by multiplexing the input signals from the connected sensors, ensuring that the NXT can read the data from each sensor sequentially.
The construction of a custom RCX-TouchMux can be beneficial for projects requiring more than four touch sensors. The design of such a multiplexer would typically involve a microcontroller capable of handling multiple inputs, an analog-to-digital converter (ADC) to process the sensor signals, and a method for communicating with the NXT, such as I2C or UART.
In building the RCX-TouchMux, considerations should include the power supply requirements, signal integrity, and the physical layout of the circuit to minimize noise and interference. Additionally, the software interface must be designed to allow for easy integration with the NXT programming environment, enabling seamless control and monitoring of the connected touch sensors.
Overall, the RXMux and the custom RCX-TouchMux represent significant advancements in expanding the capabilities of the NXT robotics platform, allowing for more complex and interactive robotic systems.Mindsensors do make a very good a RCX Sensor multiplexer for NXT, the RXMux which allows you to connects up to 4 RCX style analogue sensors to your NXT. The RXMux Supports the following Sensors: As I often use more than 4 Touch Sensors in many of my Robots, I needed to construct my own RCX-TouchMux as there is no commercial equivalent to my Knowledge available.
