Title: I'm building a robot
Post by: johnny666 on March 27, 2008, 02:36:13 02:36
Hi, I'm building a robot.  It is modeled loosely after the Johnny5 robot from the movie Short Circuit.
It will be about 3.5 feet tall and will have functional arms (2-degrees of freedom Shoulders, 1-degree elbows, 1-degree wrists, and a 3-finger gripper), a homemade tank-track system of my own design, and will be controlled by PIC and also radio-control.
If anyone is interested, I can post diagrams and photos as I build this.
I'm completely new to PIC microprocessors and will be looking in the forums here for help, so please don't be a stranger if you think you can help me learn this!  Thanks  :)

I am in search of PicBasic Compiler.  I have some experience with BASIC programming and so I think PicBasic would be a good choice for me to begin my quest.

PS-- I just joined Sonsivri today!  I look forward to it!  ;D

That's a lot of movement for the robot, what will be its main purpose?  I'm interested if you've made any progress in the RF department.  That seems to be my hangup.  If you want in the FTP of circuit cellar 199 there is a folder called caruna 199, in there they have how to set up RX and Tx to talk to each other, however, I don't believe 100% right because I haven't had success making it work yet, but its a start.

Here two tutorials by me... about building a robot...
Although I use ATMEL and the BS2, and the second tutorial isn't finished...

Have a look:

And here is something about electronics generally:

I know I must not promote only my work so please have a look here:

are you done with your robot ?
i've already created some robots and robots are not easy to build especially when you have limited resources
how many percent are you in your project ?

Would the radio control system control direct as in a model type system via servo's?
Or are you looking to control and monitor the PIC MCU and then in turn that controls the servo's?

Good work...:) I have already design and building a mobile robot. I use a MCS51 mikrokontroller with DC motor. While my robot run on the track, it isn't run follow the track becouse I'm not use a control system into DC motor.

u should use closeloop control and PI or PID technique it will good

Good idea... i try to use a PI control but I still learn PI control.

I am sure that they can. You can use more PICs connected via USART or I2C. I builded one robot with 3 PIC and it is working well. One PIC is for movement (16F84A), second for communication (16F628) and thirdt for control (16F818). Comunnication is I2C using I2C RAM PCF8570.
