Introduction: Blu Media Robot ( Update)
blu is a robot working with makeblock motherboard and raspberry for the electronic
for the part list you can buy from makeblock like me a the beginning , now I have a 3d printer (wanahoa i3 +)
and you can download the different part to print them on this website
I start the robot one year ago ,when I start robotic on my day off. I improve it as same time as my knowledge. English isn t my mother langage.
my goal: _all my media on it (music,movie,series tv ,picture)
_ server nas and kodi(raspberry media app) to read them with the hdmi output or with your tablet, computer.
_control it with android apps, raspberry, internet
Step 1: Part List
for this robot you need
_ a raspberry pi 3b +
_ a ps3 cam
_battery for the both card
_ wireless keyboard (rii mini8)
_ 2 me RJ 25 adaptator
_ me bluetooth(optional)
_36mm Codeur DC Motor Pack
_ 3 servo motor
_screw different size
I printed some beam from there and baught the rest
Plastic Timing Pulley 62T 4-Pack
8x Bracket 3x3
8x Plastic Timing Pulley 90T For Motor
5x Plate 3 x 6
2x Plate 0324-088
1x Track With Track Axle(40-Pack)
PLA filament for the 3d printer
Step 2: Building the Base
the picture will help you to understand me
base:7x Beam0824-192; 7x Beam0824-080; 7x Plate 3 x 6;
Take 1 Beam0824-192, and 1 Beam0824-080 fix together I use the plate 3x6 ; do that with the 6 other.
fix them to make a strong base
backwheel:36mm Codeur DC Motor Pack timing-pulley-90t-blue-4-pack;
ln the pack you have everthing to fix them and the back and pulley as wheel
frontwheel: 1 servo ;1 custom beam;4x Beam0412-044; 2x Beam0412-060; 2x Bracket 3x3; 2x Plastic Timing Pulley 62T ;
I made a servo bearing for the direction
the pulley 90T are fix to 2x Beam0412-044 and a bracket 3x3
fix the Pulley 62T center to the bracket
fix the Pulley 62T top to the base
fix the Pulley 62T bottom to Beam0412-060
fix the Beam0412-060 to the custom beam
repeat the previous part for the second wheel
after you just a to fix the servo to the base and is arm to the custom beam
to finish I fix my hard drive and the hub usb
Step 3: Building Second Part
10x Beam0824-192; 2x custom beam;
on the picture you can see the 10 vertical beam and the 2 custom horizontal: 1 for the picoprojector and 1 for the cam at the front at the back we have a box to put some mess on the cover it s my keyboard older I found it on internet, on the top of the box there is the powerbox to turn on off the robot and the raspberry the batery level display
Step 4: Building Inside
I made some level between the different card to have something more clear
the second picture represent my sound system old broken beats speaker I baught a 5v amplifer and a filtrer
and the last one is my top back left robot covering with usb hdmi and ethernet port
Step 5: Wiring
so I draw a schema it s more easy to understand
Step 6: Programmation
all the link in this part are tuto to help you
there is my arduino skectch(bluorion) and my python script for the raspberry(blu.py and bluorionnocam.py)
for the rpi
after I create shortcut
I follow a tuto to make a nas with my rpi like that everybody on my wifi have on an access to my video and my music.
I found this one and use the script to control my robot by internet.
Step 7: Modification
so I had few custom pieces
a can holder at the front
I had a tablet holder on the left side (to see my desktop and access to my hard drive),
rii keyboard holder 3d printing (I found it from internet ask me I will give you the link)
a box for the mess behind the keybard holder.
on the right side I put my power supply (for the robot and the video projector)
the power supply:
I buy a laptop power supply like this one I plug it directly on my videoprojector and I plug a dc step down at the battery voltage. after you just have to put a switch battery/power supply.
I change the ultrasonnic sensor and I put 2 other less expensive
I will change my battery 7.4v to 12v and a bigger capacity and I would like to plug it to my raspberry to see the capacity on my desktop
We have a be nice policy.
Please be positive and constructive.
