Arduino controlled robotic arm2/12/2024 I used the controll board shield that came along with my robotic arm kit. Once the structure is assembled, you'll be ready to wire up the circuits. The gripper has some gears, which will turn the rotation of the servo into a linear movement of the gripper. On it's top, servo #6 is connected using some bolts, nuts and a metal horn. The gripper is then connected to servo #5 axis. ![]() The fifth servo is connected perpendicular to servo #4 using another servo bracket, installed using four M3 bolts and nut.Another servo bracket is connected to the servo. Similarly to the previous step, servo #4 is mounter to the U bracket using four bolts. Another U bracket is connected to the L shaped profile using a set of four M3 bolts and nuts.Notice that another bearing is used oposite to the servo axis, as described before. A servo bracket is connected to the servo motor, and a L shaped profile is linked to the servo bracket using some bolts and nuts. On the other end, servo #3 is installed, using a circular metal horn and four bolts. Another U bracket is mounted using four M3 bolts and nuts.This way the U bracket is tightly attached to servo #2 center axis. A bearing fits on this bolt, and it's locked in position using another M3 nut. Notice that a M3 bolt is used oposite the servo axis. An U bracket is then attached to the horn using four bolts. Servo #2 is installed with four M3 bolts and nuts, and also uses a circular metal horn. It's connected to servo #1 horn using four M3 bolts. Another servo bracket is mounted perpendicular to the previous one.They won't be used for assembling the robot. The kit comes with several plastic horns. A circular metal horn is attached to the servo axis. Servo #1 is place on it's top, and attached using four M3 bolts and nuts. This profile is attached to the base using four M3 bolts and nuts, as it's shown in the pictures. The first servomotor is mounted perpendicular to the base, using a servo bracket.It's made of two U shaped brackets, joined back to back using four M3 bolts and nuts, as shown in the pictures The first part to be assembled is the base of the robot.You can use another robotic arm kit, assemble it and jump directly to the electronics and programming steps. If you doesn't have a similar kit, feel free to jump some steps. In this step I'll show you how to assemble the arm kit (mechanical parts) I've used ( link). In the next step I'll show you how to assemble the arm kit before wiring up the circuits. There are some awesome projects you can 3D print, for instance. You might find other robotic arm kits online ( link), or even design your own. MPU6050 3-axis gyroscope and a 3-axis accelerometer ( link).NRF24L01+ Wireless Transceiver Module ( link).Sain Smart 6-axis mechanical desktop arm already comes with the following components: ![]() If you you're not using on of those kits, you might use other Arduino boards as well Notice that the robotic arm kit I've used also has a board and controller bundle that already comes with this Arduino board. It receives signals from the control interface to be performed by the Arduino This awesome kit already comes with several components as described bellow.
