Simplified inverse kinematics model for a 5 degree of freedom + gripper robotic arm (2011)

The following describes a simple method (inverse kinematics) of calculating the angles for all joints of a robotic arm to obtain a desired position of the end actuator (gripper). The video bellow shows the algorithm at work. The picture bellows shows the robot arm used for this example. It has 5 degrees of freedom: 1.… Read More Simplified inverse kinematics model for a 5 degree of freedom + gripper robotic arm (2011)

Robotic Arm, Lego gripper + Lynxmotion Servo Erector elbow, shoulder and base version (2010)

Experimental robot arm with 5 DOF (Degrees of Freedom) plus actuator (gripper). The Lego version was to shaky and weak so replaced from the elbow down with Aluminum Servo Erector brackets from┬áLynxmotion. Gripper, wrist and wrist rotate made with Lego Technic and aluminum parts, elbow, shoulder and base made with Lynxmotion parts. Parallax Propeller Proto… Read More Robotic Arm, Lego gripper + Lynxmotion Servo Erector elbow, shoulder and base version (2010)
