A week ago, we reported on an open source 3D printing project from Endurance, the BB-8 Selfie Robot (SelfieBot). Now the company continues to upgrade this project! Now it doesn't need to use a battery or connect to a power source to be outdoors. How did it do it? solar panel!
Endurance stringed together two small pieces of solar panels (5 volts each). They are available in series with 10 V and 800 mAh output power. This current is not very large, but if it is on a sunny day, the robot can work. In order to get the BB-8 working, you also need a mobile phone or tablet that can be charged with the same solar panel. Endurance decided to add a new feature - the wireless charger. It consists of two units: a charger and a receiver. The receiver can be connected to the smartphone via a micro USB port.
Inside one of the panels is a hidden wire reel that produces an electromagnetic field. The other tablet converts the electromagnetic field into electrical energy, which is connected to the phone and can charge the phone. Obviously, this charger is very inefficient, but it is also sufficient. The maximum current is 800mAh. It is understood that in clear weather, SelfieBot can rely on three solar panels to work. Obviously, the larger the panel, the better the effect.
Because the exterior is more noisy than the interior, and the speakers on the phone and tablet are not powerful enough, Endurance decided to connect another passive speaker to the BB-8 via the mini jack. This can be done because the BB-8 controls motion through WiFi and controls the electronics via Bluetooth.
Stay tuned for more updated project developments, including improved stability, improved sound insulation and coloring the BB-8!
In addition, Endurance is designing a GoPro base, a wireless charger base, and the company's design team has improved its fasteners to make it easier to assemble.
