How to Build a Two Wheeled Robot
Wheels are by far the best choice for your homemade robot projects, as they require the absolute least number of components and required expertise to build. Also, if built and balanced properly, a robot can make successful use of a two-wheel system. The actual building process for a two-wheeled robot is fairly simple, and can be completed in roughly an hour or so.

Things You'll Need
- Two 6-inch diameter rubber wheels
- Two 3-volt DC motors & mounting hardware
- One 6-inch lightweight plastic/metal rectangle
- One 6-volt battery pack with wiring & mounting hardware
- Soldering iron & solder
Instructions

-
1
Insert the turning shafts of the DC motors into their corresponding slots on the wheels. Make sure the connection is solid and that the wheels can turn without wobbling.
-
2
Mount the wheel-attached motors to the furthest-apart ends of the rectangle using their mounting hardware. The motors should sit snugly without wobbling.

-
3
Mount the battery pack to the very center of the rectangle with the mounting hardware included.
-
4
Attach and solder the positive wires from the motors to the positive wire coming from the battery pack.
-
5
Choose a control scheme for your robot, like "RC" (remote control), or automatic function based on light or sound input. The control scheme will be mounted directly onto your robot's main body (wherever you have room) and will connect to the free ends of the motor wires.
If your robot requires another power source for the control scheme, that too can be mounted right to the robot's body for maximum functionality.
