PIC Serial Port Servo Controller

The PIC Based servo controller is a small project that allow you to control some robotics. The project uses a PIC16F84 microcontroller from Microchip to drive servo motors and digital outputs. It receives commands from a host computer via a standard RS232 serial interface.

CAN-Servo Controller

This dsPIC30F4011-based servo (position) controller receives commands via a CAN. If a DC motor does not have a rotary encoder, you can plug a contactless magnetic rotary encoder (CMRE) module into the board (via two SIL connectors) and provide (in a self-contained unit) rotary encoder and position control.

Mariano Lizarraga Fernandez, the designer, explains that the board in this project also fully configurable via a CAN network and no power-cycle is necessary for any change to take effect. The board has programmed PID controllers with selectable parameter from user. The controller gains, maximum and minimum pwm commands, and device ID are also configurable. All configuration values are stored in the dsPIC's EEPROM so once it is configured at the full contempt of the end-user, no more changes are required.

One Motor Walker Robot Without uC

Robot is interesting electronic project. We often see that robot project need a microcontroller as main processor. But if you don't have any programming skill yet, don't worry, you can build one motor walker robot by Jerome Demers. Yes the it's a walker robot without a microcontroller. The robot is base on the principal of B.E.A.M robotics! Building simple and elegant robot inspired by insect.

Microcontroller Based Motorcycle

A 13192-EVB serves as the basis to test a piezoelectric vibrating gyroscope-based balancing system. Replacing the original radio controller in a toy motorcycle, the board now drives the remote-controlled unit. The steering control mechanism was replaced with a more precise RC servo. The piezoelectric vibrating gyroscope provides fast turn rate indication for use in stabilizing the cycle while the motorcycle is running. This MC9S08GT60 microcontroller-based project designed by Jay Schroff.

Electronic Project : Servo Tester 2

If you want to check your Servo, i think this electronic project is suitable for you. The project use microcontroller AVR AT mega 16 as main processor. The Servo Tester 2 is hardware and software that, basically, makes a pulse width signal between 1 and 2 ms. This is the signal used to control common R/C servos. This one has some advanced features, not usually found on servo testers. This project created by ejberg

Feature list:

• Generates two separate signals for driving two servos.
• Sweep mode for stress testing servos.
• Input for reading a servo signal (from a receiver).
• Receiver signal quality analysis.
• Very high resolution at both input and outputs. 0.1µs (which equals 10,000 steps between 1 and 2 ms).
• Voltage and current readout. How much current does your servos actually consume? How much does your receiver pack drop under load?
• Simple user control. Access all features with just a single rotary knob with integrated push button.
• 2 x 16 character LCD.
• Optical tachometer.
• RS-232 connection. Write your own program (PC or whatever), that can control every feature of the tester.

PIC Robotic Webcam

Main parts to built PIC robotic webcam are two servo motors and microcontroller PIC. This eletronic project not too hard to build it if you have some electronic basic and programming the microcontroller. For the main processor this project utilized PIC 16F84. The total cost of the project is about 40 Euro (40$). All the software/code can be downloaded as free or shareware.
