HEBI Kit Router Reconfiguration Basic Info

You are more than welcome to reconfigure the Mikrotik routers that we use in our kits to your needs if you feel comfortable doing so. However, it is hard to remotely support and reconfigure routers for customers so we generally don't set them up in custom configurations - we let our customers set th...

Re: Connet Lidar sensor for Igor

Hi,

Using a USB to Ethernet adapter will work fine in this situation and it should not have any negative effect on the actuators as it will be on a separate network.

Thank you,

Re: IMU Saturation

Hi Hans,

The IMUs in all of the modules are set to saturate at 2G acceleration and 2000 degrees/second rotational speed. I don't believe we expose this in the API.

The IMU in the module is either a TDK ICM-20602 or MPU-6500, which have similar specs.

Thanks,

- Curtis

Re: HEBI I/O Board (Rev C) - I2C and Digital IO Commands

Hi, One other note - the "analog" outputs are actually PWM outputs that run at 20Khz. To get an analog output, use a R-C low pass filter to remove the carrier frequency. Here is some general information about how this works: https://www.allaboutcircuits.com/technical-articles/low-pass-filter-a-pwm-s...

Re: Network topology discovery

Hi, There is not really an easy way to determine the order. The connected group functionality is specific to the snake modules - they have serial connections between each module in addition to the Ethernet connection. I know Dave has messed around with using the IMUs coupled with some amount of move...

Re: Actuator Reverse Polarity Protection

Hi,

Yes, both the actuators and IO boards have reverse protection.

Thanks for the question!

I/O Board GPIO Voltage Configuration

We recently had a question about configuring the GPIO voltage on the I/O Board. The I/O Board supports either a 5V or 3.3V GPIO voltage and it is configurable using a jumper near the power input connector. When the jumper is placed in the "3V3" position, the output voltages are at a 3.3V level and t...

M-Stop Electrical Specifications

There was a question recently about the electrical specifications for the m-stop input to the x-series actuators. The m-stop signal uses the two "extra" pairs of wires in the Ethernet connector. Using the standard wire color convention these wires are blue, white/blue, brown and white/brown. In the ...

Re: Actuator modules not getting IP

Hi, The first thing that I would do is the verify the physical network connections between the actuators. Each actuator has two Ethernet ports and each port has a set of LEDs that indicate that that port is active. Make sure that each port that has a network cable plugged into it has active LEDs whe...

Re: Mobile I/O I2C

Hello, Currently the I/O board does not support I2C, although you are correct that the hardware is there. We have talked about incorporating this functionality in the future but so far it as stayed pretty far down the priority list. What type of I2C device are you trying to interface to? Any feedbac...
