hello everyone. i recently got started in robotics. my first project was the VEX system and i’m trying to grow out of it. But i have a question. how what motors should i get and how would i connect those to a microcontroller?
i mean really, it cant be as easy as ploping so buttons down. plus when i program a robot how do i get it to understand what its motors are. HELP!!!:eek:
-Me:cool::DI just got done programming a chip that works with the “VEX” transmitter and receiver to run DC motors. You can find the info. at: robotics.scienceontheweb.net
Hi ardenfrichette,
Welcome to the RobotShop Forum. VEX is quite a versatile system - VexRed has a microcontroller and a wide variety of sensors (the Vexplorer kit - VexBlue is only remote control). Did you consider recylcing your Vex mechanical components and using VexRed electromechanical parts?
The only differences between VexRed and custom robotics projects are:
All parts are modular and can be reused
The “microcontroller” includes motor control.
All sensors can be directly connected to the microcontroller without additional electronics
Must choose from Vex selection of parts and products
The similarities are significant:
VexRed projects are custom
VexRed microcontroller needs to be programmed
VexRed sensors are complex and also require programming
If you are looking to proceed with more custom solutions, the majority of motor controllers connect directly to the digital output pin of a microcontroller. There are several different ways a microcontroller can control (communicate with) with a motor controller including PWM, Serial, I2C, Analog and R/C. The RobotShop Learning Center is the ideal place for you to begin learning about custom robots.
We hope this helps,
