“doctoboggan” has created a project with a Raspberry Pi and Android App working in tandem to drive a remote control car.

Original article here: Show HN: I built a Raspberry Pi/Android driven toy car | Hacker News but reblogging to include the images in-line to make it easier to read!

And I quote…

This is the current iteration of the car.

Details:
I wrote a simple android app that streams the accelerometer data from the phone to the pi over a simple socket. The pi then uses this data to drive the DC motor and the servo motor. Tilting the phone to control the car feels very natural. In this pic you can see the wifi dongle I’ve used.

I am using Adafruit Occidental v0.2 as my OS because it has support for my wifi dongle. It also makes some hardware interaction easier and comes pre-installed with some good python libraries.

Here is a picture of the breadboard.

I am using the L293DNE hbridge chip for DC motor control. The two black wires you see coming off the board connect to the motor.

In this pic is the battery pack I am using to power the pi.

I purchased it from Amazon.

Here is a pic of the battery pack I am using for the DC motor.

Here is a closeup of the steering servo.

It is an HS-55 and I power it directly from the Pi’s 5v rail.

To control it, I use the Servoblaster kernel module.

My next plans are to add some sensors and make it autonomous. Let me know what you think.

I’m going to try to start my own robotics project with the blog posts I’ve accumulated over the past few weeks. Wish me luck!
