Are you talking about robotics for making prostheses, or robotic prostheses? The latter will require considerably more and more specialized knowledge: control systems and signal processing, switching power converters, radio shielding, etc. Programming these days tends to involve a lot of gluing libraries together. Python in general has much more extensive libraries than Lisps and Schemes. (The Python claim to fame is "batteries included".) Python also has excellent support for using libraries written in C and Fortran, which are the dominant languages for numerical modelling and math code.
