Turtle_2WD_Mobile_Platform_SKU_ROB0005-DFRobot

Function Introduction

This Kit will teach you how to build a Turtle Robot

STEP 1: Assemble Robot

Refer to Instruction Manual

Precautions:

1. Instruction Manual says nothing about how to deal with motor wire. The next pictrue tells it.

2. Finished the robot chassis.Then following the connection diagram to wire the hardware.

STEP 2: Debug Motor
