The 10 Best Arduino Robot Projects by Reggie Raye Published As the Arduino ecosystem matures, Arduino robot projects continue to improve. However, as the degree needed to control the claw is far less than others, to avoid the servo gets stuck, the range of PWM is narrower compare with other servos, from 900 to 1700. The PWM of servos are ranged from 500 to 2500, or from 0 degree to 180 degree, at which 1500 represents 90 degree. Average (40 - 80) Safety No issues Credits Ben Finio, PhD, Science Buddies Popsicle Stick Robotic Arm with Arduino Objective Design and build your own working robotic arm. Servo Lowest PWM Movement Highest PWM Movement It is dangerous and the servo may burn out.ĭuring the test I've jotted down the maximum and minimum PWM, and the movement of the servos as follow: Robotic arms are widely used in industries for automating a certain task such as assembling a car or designing an Arduino board. Also, don't slide the bar further if the servo gets stuck already. As the servos react to the bar I slided instantly, if sliding the bars quickly, the servos will move quickly and you may get hurt. Now I can test the servos by sliding the bars slowly. Then open the software, choose the COM port and click "Connect". Open Device Manager in Control Panel and you can check the COM port of the controller. It can be controlled by multiple people to try and achieve a common objective. Thus, 'Muscles' the quirky robotic arm came into being. ![]() Next, I install both the driver and the software of this controller to my PC, and connect the controller to PC via USB. The project started with an idea for a series of videos that would help enthusiasts build their first robot, which then developed into, building an interactive robot with the objective of community bonding in mind. The left red LED indicates data transfer. The left green LED is the chip power indicator and the right green LED is the servo power indicator. The servos are powered with VS and GND of the blue terminal block on the servo controller, so red wire of 7.4 Li-Po battery is connected to VS and black wire to GND.įor the chip we can either power it up with the pins 5V and GND next to S1, or via USB, or VSS and GND of the blue terminal block. The servo controller is fixed at the side of the base with standoff. I've also bundled the wires with plastic cable ties. Make sure all the cables are in correct direction. Next place a servo motor in the middle and glue it in place. Use extension wires if the servo cable is not long enough. Take a flat and stable surface, like a table or a hard card board. ![]() To make it simple I connect the servos from the base to the claw to the servo controller with a sequence from S1 to S6 respectively. The brown color of the wire in servos represents GND, red is + and orange is for signal. I wanna do a test with my PC first before connecting to Arduino. ![]()
