![]() This Robotic Arm can be controlled by four Potentiometers attached to it, each one used to control a. Black for GND, Red for POWER and Yellow for SIGNAL. In this tutorial we design an Arduino Uno Robotic Arm. You may use a Short Servo Mounting Screw to secure the horn and improve the precision of the arm. Place the Upperarm at a 90 degree angle to the Base and apply the servo horn. I use standard Hitec and as all servos, they have 3 different color cables. In this step, we will make all the necessary connections, Refer to the pictures above. Connect the Shoulder to the Shoulder Yoke. ![]() Brain: Brain and heart of our robotic arm is an arduino Yun. Gripper: For the gripper i used an Actobotics Aluminum Channel & ActoboticsStandard gripper kit A also with a HitecHS-311 standard servo. It is very important to know the purpose of every cable of your servos. Arm: For the arm i used an Actobotics Aluminum Channel & a couple of round plates from old hard disks. How To Make an Arduino Robotic Arm Controlled by Touch Interface-Link to the article. The cables from the other servos can be extended with the male-to-male jumper cables. Very easy, connect the extension to the servo cable (be sure not to confuse the colors) and take it through the 15" channel way to the end where the hard disk plates are. Next we have to extend the gripper cable. ![]() Take the dual side mount A and from inside the channel with 2 head machine screws, connect them to the dual side mount E from outside the channel. 2 x 12" Standard duty Servo extensions (I had only 2, you can use 4 to extend all 4 servo cables).4 x zinc plated socket head machine screws.even though in the video i posted are 4 monitoring programs. the reason that i used the servo controller is because with it i can controll the speed and the acceleration for the servos. 2 x Actobotics 90 Degree Dual side mount A the robotic arm grabs an object after it detects it using the motion detector and then it moves it at a specific location.2 x Actobotics 90 Degree Dual side mount E. ![]() We will use 4 mounts to make 2 holders for the gripper servo cables. They look better & is safer for your arm. It is very important to have your cables in order. ![]()
