DIY 6DOF Robot Arm 4 Axis Rotating Mechanical Robotic Arm for Arduino

The robot arm model is the ABB industrial robot structure proportion model. It can actually control the motion of the robot arm model according to the numerical control idea. It is suitable for teaching experiments, focusing on action demonstration, and has no actual load-bearing ability.

 

The material of the robot arm:
 

The plate of the manipulator model is pvc engineering plastics and is made by CNC machining. The mechanical bottleneck of the robotic arm is the torque of the servo, the plate of the manipulator has not been deformed and the servo has no power. Another advantage of the pvc engineering plastic is that the ductility of the material is very suitable for the inlaid bearing, and the bearing connection is used to increase the accuracy of the structure. All joints of the arm have high quality bearing connections. 

 

Six degrees of freedom of the robot arm:
 

a: waist 0-180 degrees

b: The big and small arms interact with each other, and the rotation angle range is variable.

c: The big and small arms interact with each other. The rotation angle range is variable.

d: arm rotation 0-180 degrees

e: wrist 0-180 degrees

f: claw 0-180 degrees

(0~180 degrees is the theoretical value, the actual angle is between 5~175 degrees)

 

The accuracy of the robot arm:
 

Because the power of the robotic arm model is the steering gear used in the model industry, the internal gear used in the steering gear is an ordinary reduction gear, and the gear clearance is expressed in the wrist with a free stroke of about 4 mm, which is suitable for teaching and control theory verification and is not suitable for industrial use. Production line.

 

A full set of six-axis mechanical arm factory pre-programmed action to do the test, The robot arm can be operated by plugging in the power supply., Need to do different actions can be programmed again.

 

The six axis full set of control:
 

The robotic arm is controlled by an MCU. In the computer ide software, the robotic arm motion is edited in C language. Through the usb line upload to the MCU, the MCU can independently control the robot arm to complete the action from the computer. (Provide tutorials and control example code)
