The Steam Workerbot is the most expensive workerbot resource-wise and requires logs to charge, but has better carry and inventory capacity compared to the Basic Workerbot. It also has the ability to charge itself if it has logs or other wooden items (see below) in its inventory when it runs out of charge (but cannot refuel itself if it's only carrying the items). Otherwise, you or other workerbots can refuel them by right-clicking them while carrying one of the wooden items.

Recipe

In a  Worker Assembler, you can make a  Steam Workerbot by adding:

• 4 x  Metal Plate
• 4 x  Metal Pole
• 4 x  Metal Gear
• 2 x  Water

Fuel

The following items can refuel steam workerbots:

Item	Energy	Energy per Log*
Stick	10	1440
Pole	20	720
Plank	60	360
Log	120	120

* if you're using a Bench Saw

Since you can only fuel steam workerbots when they have run out of charge and only one item can be consumed at a time, only logs can fully refuel steam workerbots. Thus, if you're using anything except logs, the workerbots will be less productive over time due to having to refuel more frequently in addition to spending more time in a low-energy state (which reduces their movement speed).
