Now i can control my robot from the web!
The Android App is just a simple program to change direction of the robot and a slide bar to change speed. But it works!
Here is the complete robot:
I’m thinking that the next step will be to utilize the internal g-sensor of the phone to move the robot.
I’m not going to use the RF link as I mentioned in the previous post. The problem lies in getting a stable link between devices. I just want it to work quickly.
Fortuneally for me I have 2 LM048 modules ready to use. It’s a Bluetooth device capable of paring. That means at startup the 2 devices will connect to each other automatically.
As you can see in my HomeRemote project I have a selection called “Robot”, well it’s time to make it work! With this old thing:
This is an old “robot” I found in my closet as you can see it has been butchered for parts to other project I have made.
To make my Android app control this I have to order some parts. As there is an existing RF transmitter on my HomeRemote I am going to control it by RF commands.
These are already on their way to me as I am writing this.
It’s an RF transceiver and a 2000mAh rechargeable lithium battery running at 3,3volts.
The Android App “Robot” selection looks like this:
It’s going to be a simple command set to control it; Forward, backwards, right and left. The button in the middle is going to be Stop or action button (play some sound?).
The project has started, Stay Tuned!
