Developer and maker Sanjeet has been building and
developing the R3-14 personal robot assistant for over two years and has used a
variety of readily available subsystems. For example Sanjeet has used Google
Assistant, 433 MHz RF transmitters, and a Raspberry Pi mini PC as components in
this build.
“Many people started out in electronics building
something simple like a crystal radio or an LED cube. But how far could you get
if your projects had to begin at the most basic level, by drawing out copper
wire, fabricating coils, capacitors, semiconductor devices, and batteries? Even
if you know how to do all those things, it would take a lot of time, so there
is no shame in using off-the-shelf components.”
“The post is interesting because it shows how the
design evolved with an initial metal prototype giving way to a 3D printed body,
and with several iterations of software. We did however wish for more details
on the software and code, and we hope more details are forthcoming. Meanwhile
the project is still a good inspiration. The face tracking drives servos to
move the robot’s head and LED eyes make it expressive.”
