A few weeks ago I've made this radio controller based on Arduino and the NRF24 radio module. Now we can see how to use it. We start with something easy. Servos are controlled with PWM signal. What we do is receive the radio signal, crewte PWM signals and control the servo turret. We als... view more

I wanted to make this project for a long time. Inspired by a projet of HowToMechatronics from a few years ago. This robot is fully 3D printed and is just the first version and is sensorless. In the future I want to add a lot more controls and sensors. This robot has 18 high torque servo motors, r... view more

Working on a new project requiring (12) ballscrew actuators prompted R&D'ing cost effective solution.This led to many months of developing a 3D printed ball screw with an encoder and hardware cost of 25$/each. Multiple configurations posted for different travel lengths.

In this tutorial we will build this balance. It is controlled with a servo motor and an Arduino with a PID code. The idea is to get the ping pong ball in the middle. To do that we will use a IR distance sensor. By knowing the distance to the ball and using the PID code to move the servo, we could... view more
