Smart Phone Controlled Robot – MobBob V2 Remix Upgrade

---

3D Design Tool: SketchUp Pro
Design concept: RAPIRO – The Humanoid Robot and Gundam

This is an upgrade version of my MobBob V2 Remix robot.

MobBob is a smart phone controlled robot. By harnessing the power of your smart phone, MobBob is a walking, talking robot with voice recognition and computer vision that you can build for around $35. I will be continuing to extend his features over time. I want MobBob to be a companion robot that everyone can afford and have fun with.

You can see videos of MobBob V2 Remix upgrade in action here:

Coming soon!!

The main aims of the V2 remix were to:

Support standard 9g servos [previously I was using Tower Pro SG90 servos]
Make everything easier to assemble [no more need for glue]
Make it easier to adapt/modify for other phones. The new bracket system made it easier to exchange a new phone / the battery holder.

Also, in my V2 Remix Upgrade build, I’m also using the Arduino Nano instead of the DIY Nano shield, so the entire build is smaller and tidier. 🙂

MobBob V2 Remix Upgrade uses the same software as the original RAPIRO.

You can find the latest Arduino code here: https://github.com/Ishiwatari/RAPIRO
The modified code is included: http://www.thingiverse.com/thing:1235865

You can download the latest version of the Android from Google Play – it is free, ad-free, and without IAP:

[Note: I got the servos, Arduino Nano, Bluetooth Module and Battery for under $30.]

Arduino Nano:

This is a small, Arduino compatible ATmega328 board with DIY extension board. MobBob V2 app connects to the Bluetooth module using its Bluetooth LE service. The app to support other Bluetooth cards.

Battery Extender:

You can use other batteries that provide 5V with a steady current. If you use other batteries, you may need to adapt the battery rack for your battery’s size.
Use 18650 Lithium Battery Charging Board With Protection Charger Module and Step Up Boost Module 3.7V to 5V for Smart Phone
http://www.thingiverse.com/thing:1235749

Smart Phone:

You can use other Android Smart Phones with This app.
You do not need to adapt the size of the phone holder for your phone. The app has been successfully tested with Nexus and Samsung, LG phones, but should work on other Android phones.

Instructions:

Print all the required parts
Get all the non-3D printed parts
Assemble as per the photos – I’ll be writing some more detailed instructions on my website soon!
Install the Arduino code from the GitHub link in the description – You will need to update the Arduino pins in the code to match yours, and probably update the centering values for the servos.
Install the Android app from the link in the description.

Have fun!

If you hit any problems, please post a question on this website: [http://www.rapiro.com], here, or on YouTube channel. A few people have built RAPIRO now, so there are people around who can help.

Coming soon update!!

The open source Mobbob V2 software and hardware is free and made with love. Please show your level of support with a voluntary donation.

on the command line, enter:
// #M1 – robot will move forward
// #M2 – robot will move backward
// #M3 – robot will turn right
// #M4 – robot will turn left
// #M5 – robot will raise his hand and wave the left hand. LED will become green and flashing
// #M6 – robot will lower his left hand. LED will become Yellow
// #M7 – robot will move both arm and contract his hands. LED will become Blue
// #M8 – robot will wave goodbye with his left arm. LED will become RED.
// #M9 – robot will raise its right arm and move its waist. LED will become BLUE
// #M0 – robot will go to initial position

CAPS LOCK is important when you input a command via the serial monitor..
Reading through the source code.
Each movement of the preset (# M1 ~ # M9), consists of pattern of 8 frames.
Each frame is defined values ​​uint8_t type sixteen (motion).
This can be changed modifying the number of frame per pattern.MAXFN
Lets take #M0 for example:

uint8_t motion[MAXMN][MAXFN][16]={
{ // 0 Stop
{ 90, 90, 0,130, 90,180, 50, 90, 90, 90, 90, 90, 0, 0,255, 10},
{ 90, 90, 0,130, 90,180, 50, 90, 90, 90, 90, 90, 0, 0, 0, 0},
{ 90, 90, 0,130, 90,180, 50, 90, 90, 90, 90, 90, 0, 0, 0, 0},
{ 90, 90, 0,130, 90,180, 50, 90, 90, 90, 90, 90, 0, 0, 0, 0},
{ 90, 90, 0,130, 90,180, 50, 90, 90, 90, 90, 90, 0, 0, 0, 0},
{ 90, 90, 0,130, 90,180, 50, 90, 90, 90, 90, 90, 0, 0, 0, 0},
{ 90, 90, 0,130, 90,180, 50, 90, 90, 90, 90, 90, 0, 0, 0, 0},
{ 90, 90, 0,130, 90,180, 50, 90, 90, 90, 90, 90, 0, 0, 0, 0}
},

I put numbers so you can visualy make sense of what a pattern is, and what a frame contain.
Movements consist of pattern. Pattern are made of frames. Each frame contrain the rotation angle of every servo, the values of the RGB LED and a Time to perform the action.

Head horizontal rotation angle (Head yaw) (left) 180 <—> 0 (right)
Hip horizontal rotation angle (Waist yaw) (left) 180 <—> 0 (right)
Right shoulder up and down angle (R Shoulder yaw) (bottom) 0 <—> 180 (above)
Open right shoulder angle (R Shoulder pitch) (closed) 90 <—> 180 (open)
Right hand opening and closing angle (R Hand grip) (closed) 50 <—> 110 (open)
Left shoulder up and down angle (L Shoulder yaw) (bottom) 180 <—> 0 (top)
Open left shoulder angle (L Shoulder pitch) (closed) 90 <-> 0 (open)
Left hand opening and closing angle (L Hand grip) (closed) 130 <—> 70 (open)
Right foot horizontal rotation angle (R Foot yaw) (left) 0 <—> 180 (right)
Twist angle of the right foot ankle (R Foot pitch) () 0 <—> 180 (outside)
Left foot horizontal rotation angle (L Foot yaw) (left) 0 <—> 180 (right)
Twist angle of the left foot ankle (R Foot pitch) (within) 180 <—> 0 (outside)
Red component of the eye (R) 0 <—> 255
Green component of the eye (G) 0 <—> 255
Blue component of the eye (B) 0 <—> 255

Here are some other helpful commands that can be used to control the LED and each servos individually.

LED CODE sample

// #PR000G255B000T010 – MAX GREEN COLOR
R,G,B values between 0 and 255
T is the time component to get to desired color

LIMBS MOVEMENT
Sxx refers to one of the 12 motors (from S00 to S11),
A000 up to A180 is the angle where to servo incline,
Txxx is the time to perform the movement.
you can combine two commands, i tried more but it didn’t work..

// #PS00A000T010#PS00A180T010 – full head movement from side to side
// #PS01A000T010#PS01A180T010 – Waist
// #PS02A000T010#PS02A180T010 – r Shoulder
// #PS03A050T010#PS03A180T010 – r Arm
// #PS04A030T010#PS04A140T010 – r HAND
// #PS05A000T010#PS05A180T010 – l Shoulder
// #PS06A130T010#PS06A010T010 – l Arm
// #PS07A030T010#PS07A180T010 – l hand
// #PS08A000T010#PS08A180T010 – r Foot yaw
// #PS09A000T010#PS09A180T010 – r Foot pitch
// #PS10A000T010#PS10A180T010 – l Foot yaw
// #PS11A000T010#PS11A180T010 – l Foot pitch

// #PS00A090S01A090S02A000S03A090S04A090S05A180S06A090S07A090S08A090S09A090S10A090S11A090R000G000B000T005
