Bot Bench I'd Rather Be Building Robots
Deepak from Mindsensors told me they have a new device coming out soon: a Sensor MUX for the NXT and EV3.
What makes this one different from the MUXes out there? Well for one, it’s very compact, only 42 mm x 48 mm, with mounting holes in a 4 x 5 studs square. Other features include:
- Support for all EV3 sensors (UART + Touch sensor), so this is not made for MUXing NXT I2C sensors
- No need for an external power supply
- 3 channels to access the data from the sensors
- An I2C interface, so that will allow you to use EV3 sensors on the NXT
- Automatically detect which sensor is connected, and begin polling, using the block user can then read the data in the program
That’s pretty cool and if all goes according to plan, I should have one by the end of November for beta testing. There is currently no other technical information available but I’ll keep you posted if I find out more!
Hi Mr Xander.
I use Robotc and an EV3.
I red that actually there is not a driver for that Mux.
I can buy it now, it is available, but … how long I must wait for the driver.
Thanks!
Hi there,
The driver is here: https://github.com/botbench/robotcdriversuite, just browse around, you’ll find it 🙂

Wow, thank you for the quick answer!
I shall try your driver soon.
Best regards, grazie!
Hi Mr Xander!
We are building a new robot for rescue maze junior competition.
My students say that they cannot use 2 EV3 Mux at the same time connected to thier Ev3 brick. Is it possible to use more than 1 Mindsensors EV3 Sensor MUX to let them to use up to 12 Ev3 sensors on the same robot? Thank you in advice! Dank je!
Hi there,
I have not tested it with more than one and all of my sensors are currently in storage, as I just moved to another country. What makes the kids believe you can’t do this? I don’t think I have anything specific in my code that would prevent this.
First of all thanks for your quick replay.
I waited a bit to make some experiments with two mux connected to one EV3 at the same time. No problem, they work fine.
My students misunderstood some part of your driver.
thanks again and merry Xmas!
Dear Mr Xander, a question for you: I am using the EV3 sensor mux with EV3 Gyro attached to it. Is it possible to reset the Gyro sometimes during a rescue maze session? My sudents told me they do not know how to do that because the reset function works only if the gyro is connected directly to one of the EV3 brick port and not through the mux.
Some tips?
Thank you in advice, dank je!
