Predictions are often made of intelligent and independently mobile robots for the disabled, and researchers are continually improving laboratory systems. Reductions in the cost of the technology involved may lead to affordable devices by the end of the decade. Less ambitious goals must be adopted by those projects wishing to distribute robotic aids to the disabled in the next few years. A modest selling price dictates the use of existing components. Even with the advent of more advanced robots, cost considerations may still make simpler devices on attractive alternative. Excessive optimism of future capabilities should be avoided, lest unrealistic expectations of current robotic aids hamper their development. Progress at all levels of rehabilitation robotics is complementary.
