In the future, you will be able to build custom robots using intelligent building blocks. HEBI Robotics is already working on such solutions. Its robotic building blocks platform allow you to customize your robots for specific tasks cheaper and faster.
The X-Series Actuator module allows engineers and researchers to create custom robots of any configuration. Their sensors allow controlling of position, velocity, and torque. Each module has brushless motor, geartrain, spring, encoders, and control electronics.
