Design and Material

The robot was designed by Sketch Up 2017 Pro on an actual side scale of 1:1.

then I print it out using a laser cut machine on an acrylic board of 3mm thickness.

Actually, that wasn't easy to maximizing the DOF using four servo motors only, and at the same time, I had to maintain the human form for the robot.

Gripper

I was keen to design the gripper consistent with the rest of the design and to be as humane as possible.

and It consists of Three groups of parts Thumb, palm, and fingers connected together using 5mm plastic spacers as shown.

Tip1:using plastic spacers are very effective to reduce the weight and thus increasing the torque of the motor.

* The gripper design is available to download

Elbow and Arm

The design of the wrist motion is based on the servo motor that connects the forearm to the hand.

Tip2: Use strong acrylic adhesive to glow the motor bracket to the forearm.

Torso

Basically, The torso was designed to contain electronic components such as Arduino Board and the motor shield.

* The design is now available to download.
