Here is a robotic platform that you can program and build new skills for it. The Misty I robot allows you to use APIs for autonomous navigation, speech, hearing, and vision. It comes with USB and serial ports, so you can add new features to it. Misty I is programmable via JavaScript and Blockly.
Misty I will be available for $1499. The next generation Misty II is coming later in 2018.
