InMoov Touch Sensor (Full Bridge Strain Gauge)

Gareth's picture

Here I present a "Touch Sensor" for InMoov's finger tip

Its uses a Full Bridge Strain Gauge circuit, this consists of 4 resistive strain elements and an instrumentation operational amplifier.

Basic Full Bridge :-

[1] Two active elements (one placed on top surface , other placed on bottom surface)


CMUcam5 Pixy - first impressions

Gareth's picture

Here is some test data that I am working on to check out the capabilities and speed of a CMUcam5 Pixy camera.

I am using two interfaces to set the system up :-

1. USB plugging into the Pixy allowing the PixyMon Gui to monitor,adjust & capture objects (by colour).

2. A connection between the Pixy<> Arduino on the 6pin ICSP port (aka SPI (Serial Peripheral Interface))

Here is the current working system.

The design 3D STL print files can be found here Chiprobots Thingiverse Channel

Below you see the Nema17 Stepper motor ,Actuator,ESP32,ramps controller birds nest.


ESP-Wroom-32 Web Server meets some Nema17 stepper's

This is a walkthrough on how to control Nema17 Stepper motors using an ESP32 Webserver.

In the example above I am using the local ESP32 webserver to control InMoov's neck screw via a Nema17 stepper motor and 3D printed Gearbox.

Controlling Stepper motors via a Wifi enabled webserver opens up an easy way to control remote devices. The information here shows how this can be done easily and at low cost.

I have been looking for a fitting clock to match with a Mongolian shelving unit,

it needed to be retro so no option...... Nixie Tubes !!!.


The ins and outs of Kinect programming

Great series on how to access Kinects goodies via processing by the guy who wrote the original hacked drivers for it. Well worth subscribing as he perfectly executes the cavets in "Processing" language  , fast paced to the point and fun.


Google Deep Dream - the future of predicting things before they happen !!!

I bumped into this Video below explaining the process, thought it was some food for thought.

 

 

I ran Inmoovs hand through Google's Deep Dream  ( one source http://psychic-vr-lab.com )
