One thing holding back advances in mobile robotics is current chemical battery technology. The power-to-weight ratio is not adequate, charging/discharging issues are problematic, they have limited life, and they're expensive. Frankly, this old-school Baghdad battery technology is pathetic. It's time for a revolution, and the folks at MIT's Laboratory for Electromagnetic and Electronic Systems are looking to change things with Nanotube-Enhanced Ultracapacitors. These are not your Granddaddy's electrolytics. These capacitors promise longer lifetimes, temperature stability, high immunity to shock and vibration, and excellent charge/discharge characteristics - Perfect for mobile devices and our Robot friends. Just think what Robots would look like and do if our battery technology was improved by a factor of 100, or even 10,000?
