You will need the following electronic hardware:

Arduino Uno
5 x Analog Feedback Micro Servo (metal or plastic gears up to you)
2 x Push buttons
2 x 1k Resistors
Breadboard
Jumper wires

The arm parts and gripper are 3D printed so you will need a 3D printer or a 3D printing service. If you'd like to replace the servos in a retail arm you already have that should be no problem.

You will need something to attach the servos to the arm pieces. Screws will do the job, but if the plastic breaks you can use hot glue. A paperclip will be needed for the gripper.

Tools:

Small drill
Blade
Sandpaper
Hot glue gun
Needle nose pliers
