Hi!

I read the description (did not watch video) and wanted to know more about the actual hardware (chip used, GPIO, power consumption, etc).

Project look great, btw. :)

I wrote a bit more detail here https://news.ycombinator.com/item?id=11903939 but

Still very alpha, specs currently are STM32F446RE (ARM M4), ESP8266 (WiFi, for control from a computer, phone...) and an accelerometer on-board. 9 channel servo control with current sensing, JTAG/USB for programming, i2c and serial interface for talking to it from an arduino, raspberry pi or other microcontroller. We're not expecting to have much GPIO free, and as I said, the firmware it's running is kinda complex, so we're not expecting most people to change it.

How much weight does the frame support? Does the weight need to be centrally located? I'm thinking this would be very nice with one of those small touchscreen displays attached to it.

It's fine with a reasonable amount of weight - I'd have to ask Sandy how much weight Marty can take before he physically can't move, but a touchscreen should be fine, and won't disrupt his walking ability much. Of course you could re-plan his walking with the weight taken into account, but that's quite complex. We'll probably have standard mounting holes on top of his head, so should be a nice and easy hack :D
