Hardware Design

Standardized Stacked Base Plates

• Inspired by the open robotic platform, our base plates have 3.5mm diameter holes spaced 20mm apart for standardized mounting

Power

• (12V version) 12v 5A Li-ion battery
• (5V version) 65W Laptop power bank

Tip

If this is the first time you build robots please choose the 5V version as it’s a little bit easier to assemble. If you are more experienced and want to lift heavier objects choose the 12V version.
