This code: for i in range(8): current = mymarty.get_motor_current(i) print("motor", i, current)
It always seems to return 0.0 for all motors: ('motor', 0, 0.0)
I'm getting a sensible value for get_battery_voltage()
I'm using python 2.7.9, Rick firmware version 1.0 (using get_firmware_version).
Can anyone confirm if they have this working?

This post is mainly to see if others are seeing similr problems - I'm going to be testing more to try to fix the problems below. I'm very familiar with Linux, use the Pi a lot and am programming stm32f4 devices as part of my work, so
I've started with the image at: https://cdn.robotical.io/public/raspberry-pi-img/robotical-pi.17.07.img.gz
I tried this with an older Pi with fill size SD, but it wouldn't fit in Marty - the micro SD ones is fine. For this reason I've not tried the oldest Pi versions,…

There are occasional noises from Marty, who is on and charging at the moment. I suspect this is reaction to the motion sensor - perhaps a note that this is normal would be a good idea.
If I'm wrong, then I'd welcome suggestions.

Marty calibration scan assumes a 192.168.0.0 class C address (192.168.0/24 in CIDR notation), hard coded in the javascript. The scan didn't work for me, nor did entering the IP address directly (the DHCP server allocated 192.168.1.59), but I sent the browser to http://192.168.1.59/service-discovery then retried the calibration page and the ip address worked that time. I may get time to investigate further later, but this may help others.

I've completed my Marty, and he's connected, calibrated and charging.
For the build I have a few suggestions for updated guidance.
Working over a smooth soft surface is a good idea to catch dropping parts. A clean tea towel is a good option, used in the football pitch so the edges would also help.
Put the nuts in the head before adding anything else!
The nuts that go into slots are easier to handle if the piece is held horizontal so they are held in place by gravity. A small blob of b…

I use a portable wifi hotspot (actually a 3G wifi router) which allows me to have Marty and my laptop work where ever I am. However the dir…

Just experimenting with this. Seems a lot better and easier to start with than the older version.
One bug I've found is that adding batt…

I suspect your network doesn't give the same domain info.
You may need to get the IP address of the Pi from your router, so if that was 1…

Very useful demonstration, and picked up Marty first time on a 192.168.13.0/24 network.

I've not got the image set up for the older Pi yet, I'll try to find time to experiment a bit more this weekend.

Another suggestion - test before putting stickers over screw for the right eye, that may need to be undone to adjust.
