If you received the pre-assembled Bittle, you need to insert the neck into the body and bend the knees to natural angles. Drag the curly wire from the knee side to the shoulder side to avoid squeezing when the knee joints rotate.
Long press the battery's button for 2~3 seconds to power on/off. Unplug the insulation sheet of the infrared remote's battery, then you can control Bittle to move.
If you ordered the unassembled Bittle kit, you will have to solve a challenging and fun puzzle. You will learn more about robotics after understanding the design logic behind Bittle. Please move to the following chapters for details.
