Introduction: R/C LEGO 'Velocipede' Droid
More by the author:
About: I am Electronic Visualization Artist. I look at things through the Looking Glasses.
I built this 'Velocipede' Droid by using parts from existing LEGO® set - "Star War 7748, The Clone Wars Corp Alliance Tank Droid" (2009) and some other LEGO Technic Bricks, Plates.
The original 7748 set (See Photo 4) contains 196 pieces. I used only 76 pieces out of 196 (approximately 38% of the set.) And I added 63 pieces using other LEGO Technic Bricks, Plates, etc.
My intension is to transform the Tank Droid into motorized robot by modified the T Pro SG90 servo to only use its motor (See Step 2 for the instructions.) And then use Palm Arduino Plus to control the motor controller (L293D) that is included on Palm Arduino Plus PCB.
And I use the XBee module to receive the commands from the computer wirelessly.
And here is how I built the 'Velocipede' Droid!

Others
3.7V Rechargeable LiPo battery or similar
7.4V 500mAh Rechargeable LiPo battery or similar
L293D (or SN754410) motors driver IC
Arduino or Arduino compatible
NOTE: I used Palm Arduino Plus in this project, since it has Motor Controller (L293D/SN754410) slot added on the PCB.
Wireless Radios
Palm Arduino Plus has three options of wireless radio modules,
- XBee module,
- RN-XV WiFly module,
- Bluetooth module.
In order to use Xbee module or RN-XV WiFly module with Palm Arduino Plus we need extra breakout board, I used XB-Buddy Basic Kit (Jameco's Part no. 2163680) or similar.
Tools
The tools that I used in this project are:
Super Glue
Sand paper
Files
Solder iron and Solder station
Hookup Wire
Diagonal Cutter
Pliers
X-Acto Knife
Wire Stripper
SolderSucker
Step 2: Servo to Motor Conversion
Following are the photos show how to convert servo to be used as the motor and assembling them to the 3D Printed Servo Mounts:
Photo 1 9g Servo.
Photo 2 Remove all four screws from the servo.
Photo 3 The PCB was broken! Not the motor.
Photo 4, 5 Close up look at the servo and it wiring.
Photo 6 I disconnected the wires from the potentiometer.
Photo 7 Then removed the wiring from the motor.
Photo 8 And I removed the three wires with 3-pin female connector at the other end from the Servo PCB9
Photo 9 Removed the cap.
Photo 10, 11 Look for the notch below the topmost gear. I used X-acto knife to slice these two notches out of the top gear to make the top gear 360 degrees rotatable.
Photo 12 Put the cover back into it place.
Photo 13 I soldered the power supply wire (red) and ground (brown) wires to motor.
Photo 14 Close the bottom with four screws.
Photo 15, 16, 17 At the other end of the connector, I used the X-acto knife tip to open the lock, then pull out the orange jumper.
Photo 18 I got all of my three broken servos converted to usable motors and ready to be used in my next project. (I will only used two of them in this project.)

- Test the motor.
Photo 19 Prepare my 3D Printed Servo Mounts (2)
Photo 20 Insert the cable into the top opening (As shown)
Photo 21 Slide the bottom of the servo into the servo mount.
Photo 22 Push the servo to the end.
Photo 23 Now the assembled servos (actually motors!) are ready!

Step 3: Assemble the Motor Axles
Following are the photos show how to modify the servo horns to be used as the motor axles:
Photo 1 We needed two LEGO Cross Axle 3L with Stud (#6587) and two servo horns that came with the 9g servos.
Photo 2 Glue the servo horn and Cross Axle together with SuperGlue.
Photo 3 Wait for the glue to dry (probably 24 hours) before proceed to the next step.
Photo 4, 5, 6 Use the diagonal cutter to clip off servo horn arm.
Photo 7 File or sand to smooth the cut area.
Now we got Motor Axles ready to be used!

Step 11: Summary
That was really fun to make something new out of something that is already exist.
The project could be extended further by adding some sensors to make the Droid to be line following robot, or adding light sensor to detect light, or some other stuffs to make the Droid doing things you want it to do.
Following are the photos of the finished 'Velocipede' Droid, and video shows 'Velocipede' Droid in Action.
Note: I tried the Droid on different surfaces. It seems to me that the smooth hard surface work best. The carpet is the worst the wheels did rotate freely, and the droid could not move on this surface at all. The rough concrete surface didn't work well either.
Also I did not used any of the Radio Controlled module in this video. I did program the Palm Arduino Plus to drive the motors by itself.
Thanks for reading.
And if you are building the Droid, I would love to see picture of your 'Velocipede' Droid.
