Robots contain electric circuits that connect the main computation unit with secondary controllers, sensors, and actuators. A part of designing a robot from scratch is to design its circuitry, both the electric characteristics and the physical layout inside the robot body.
Here is a selection of software tools for designing electrical circuits.
- Eagle is a very popular commercial product similar for schematics and PCB
- ngspice is an open-source, SPICE3-based circuit simulator
- Schematics.com is an online circuit schematic design tool
- CircuitLab is an online circuit schematics tool with SPICE simulation capabilities
