Introduction: Minion Coin Eating Robot
Minion Coin Eating Robot is a simple and easy yet creative robot to make. You can see the way the robot eats the coin. Maybe you can get saving habits by using the Minion Coin Eating Robot! This project does not require 3D printing but uses a laser cutter. Now let's start making the Minion Robot with step by step instructions.
This page will only explain the hardware setup of the Minion Coin Eating Robot.
Step 1: Check the Part List
Body, Head, Arms (Laser Cutting)
- 1 Plywood Plate (3mm thickness, 300mm x 600mm)
Arm-Head Lifting Mechanism (ROBOTIS DREAM)
SPD-3b5 x 2

Assemble the Body, arm, and head of the Minion Robot using the soft hammer.
The video shows how to assemble the parts using the soft hammer.
For the Body part, make sure you skip assembling the right side of the box as shown in the image. We will assemble this at the very last (right before putting the skins on top of the box).
Step 4: Attach the DYNAMIXEL Supporting Plate to the Body of the Minion Robot
Attach the DYNAMIXEL supporting plate to the body of the Minion Robot using a glue gun.
Mark the position of the plate using the pencil before you attache it.
Position: 41mm below the top of the plate
Step 5: Mark the Position of the DYNAMIXEL on the Supporting Plate
Step 6: Glue the Top and Bottom Parts of the Arms and Body-arm Linkage
Step 7: Arm Lifting Mechanism 1
- Use two SRV-1H/1P to connect SPO-4PR and SPD-2b5.
- Use a glue gun to attach the step 1 (above) to DYNAMIXEL XL330. (Please attach it as the image shows)
Step 8: Arm Lifting Mechanism 2
- Connect SPI-1b9 to SPI-2b5 from Arm Lifting Mechanism 1 (previous step) using the SRV-1H/1P
- Connect another SPI-1b9 to the above step
Step 9: Arm Lifting Mechanism - Connection to Head
- Connect 2 SPD-3b5, 1 SPI-1b6 to previous step using SRV-1H/1P
Step 10: Attach DYNMIXEL XL330 to the Supporting Flat Use a Glue Gun
Step 11: Attach Body-Arm Linkage to the DYNAMIXEL XL330 Using a Glue Gun
Step 12: Attach Arm to the Body-Arm Linkage Using a Glue Gun
Step 13: Attach the "connection to Head" to Inside of the Minion Robot Head
Step 14: Attach Two Joints at the Back of the Head and Body of the Minion Robot
Step 15: Check If the Arm and the Head Is Moving As Intended (When Arm Goes Up the Mouth Opens)
Step 16: Finish Assembling the Body - Assemble the Right Side of the Box Using Soft Hammer
Step 17: Print and Cut Minion Skin
