This bipedal robot is controlled by an Android smartphone through a game pad, voice commands, or sensor gloves. It uses a custom Android API, which the creators plan to make open source, and two Maestro 24-channel servo controllers connected to the smart phone via USB. One Maestro is used to read 12 digital and 12 analog inputs, and the other is used to control 24 servos.

This robot was designed and made by Seeberger Robotics & Design, a startup company based in Switzerland. You can see more of their designs on their website.

We have released three new step-up regulators that can boost input voltages as low as 0.5 V and have typical efficiencies between 70 and 90%. Unlike most boost regulators, these offer a true shutdown option that turns off power to the load. They also automatically switch to a linear down-regulation mode when the input voltage exceeds the output, making them great for powering electronics projects from 1 – 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell.

These regulators are available with a 3.3 V or 5 V fixed output voltage or an adjustable output voltage (2 V – 5.25 V).
