Power Protection Systems for NOOBs

Ray.Edgley's picture
When you think of power protection, you first think of fuses or circuit breakers. While these are the most common devices used in both home and industry, they are far from being the only type of protection device.  Normally the fuse or circuit breaker will only be part of a larger protection system.

The day when we can ask our robot to get us a beer and it walks to the fridge get the beer out and returns it to us out in the shed will be truly a great day.  There are some who say it can't be done, and those people will never achieve this ultimate goal, but as a community this goal is achievable and quite possibly before the end of next year.
 

Setting up Web Kit Speech Recognition With Mary TTS For NOOB's

This set of instructions is based on the Raspberry Pi 3 (RPi3).
To setup the RPi3 please follow the following link: http://myrobotlab.org/content/installing-mrl-raspberry-pi-3-noobs
 
In the tutorial we will be creating Python script which we can execute from within MyRobotLab (MRL)
 

Remote Access to the Raspberry Pi 3 for NOOB'S

If you haven't already I suggest reading the Installing MRL on a Raspberry Pi3 for NOOB's

This tutorial is a continuation of that tutorial and assumes the raspberry Pi 3 is configured 
the same way as described in the above listed tutorial.
 

Setting up I2S Microphones on the Raspberry Pi 3 for NOOB's

If you are using the Raspberry Pi 3, one of the option is to use I2S (Inter-IC Sound) Micropones
 
This is diferent to I2C which  is for the control of devices and will be covered at a later date.

Installing MRL on a Raspberry Pi 3 for NOOB's

New Out Of Box (NOOB) is a term used for very new beginners.
We have all been there, and with the alittle help, we learn all the time.
 
This set of instruction is for the new user with very little or no experience with the Raspberry Pi.
Most seasoned experimenters/developers will find these instruction too simple and goes into detail they do not need.
 

Fred InMoov

Ray.Edgley's picture

Fred InMoov is built using two Raspberry Pi 3 with a planned third one to be installed.

Servo Control is done using a PCA9685 Servo Driver in the form of a raspberry Pi Hat from Adafruit Industries located on the top of top moths RPi named Fred_1, This is then conneted to 3 other PCA9685 Servo Driver as stand alone boards, one located on the back, and one in each bicep.

Located in each forearm is a ADS1115_16B_4CH_I2C_ADC again from adafruit industries. This allows for 4 of the 5 finger pressure sensors to be monitored.
