Hi there… :smiley:
I’m from india… studying last year Computer Engg.
I’ve made 1 Unmanned Ground Vehicle for my last year project!! :slight_smile:

Right now we have completed with the implementation of actual model & electronics!!

I’ve intended to use wireless Blue Tooth module for wireless transmission.

This model is to be operated by computer keyboard!!
There is 1 wireless transreciever connected to the serial port through 8085 microprocessor based electronic circuit.
The another transreciever is mounted on vehicle which is connected to single/double pole relays.
The relays further operates the geared DC motors in the vehicle.

Also i’ve used micro-switches to limit the excessive movements of vehicle Arm & Gripper.

To control the vehicle by PC keyboard, we are trying to code a program in Visual Basic. The movements of the vehicle are -

  1. Move Vehicle Forward.
  2. Move Vehicle Reverse.
  3. Turn Vehicle Left.
  4. Turn Vehicle Right.
  5. Move Arm Up.
  6. Move Arm Down.
  7. Gripper Open.
  8. Gripper Close.

We are stuck at the programming stage.

The logic of the Visual Basic program is -

**The program only sends the keyboard commands (which are in ASCII code) to the serial port! **

Now the 8085 based micro. processor circuit connected to serial port recieves this ASCII code signals & converts it to BINARY CODE & forwards it to the transreceiver.

We have completed with the 8085 based program which converts ASCII code signals coming from serial port to Binary code signals for transreceiver!

Since i’m not a PRO programmer in VB, [size=150]i’m not able to code the program…[/size] :cry:
If anybody can guide me to code the program it will be very helpfull.

Thanks in advance.

I’m posting few images of it… also posting one 3d model viewer file!

I’m not sure if I can be of much assistance, but I have a basic (no pun intended) knowledge of Visual Basic.
I’m not sure exactly where you’re having trouble, though.
You said that you’ve already completed the program to convert the ASCII code to binary…
Does that mean that you still need to write a program to send your keystrokes as ASCII packets across the Bluetooth?
Let me know exactly where your stumped, and I’ll try to help…

By the way, beware of Bluetooth.
It tends to be a bit on the slow side.
Since you’re only sending ASCII one way, it shouldn’t be a real problem, but if you desire to add sensors later on…
Well, you’ll find out quickly that you’re getting your sensor data way later than it’s actually helpful.
