It's always fun to make a small robot and experiment with the movements and obstacle avoidance, however to make something that can actually walk is even better. One example of this has been documented by Kevin Biagini who created a simple bipedal robot (i.e. it has two legs) that can walk in a fasion. Using two servos for each leg, and some 3D-printer body parts Kevin's "Bob" robot can walk about and detect objects in front of it using an ultrasonic distance sensor. Here's a quick video of Bob in action:
To make your own, Kevin has thoughtfully published the files to print Bob's parts, the sketch and other details on the project page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
if you're looking for a small Arduino-compatible board to embed in a project such as Bob above, consider our LeoStick. It's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:
Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
