All animals have a variety of senses that help them in everyday life. We’ll talk about interesting non-human senses that some animals possess and the often overlooked human sense of balance which is based on accelerometers and gyroscopes in our vestibular system.

Now let’s talk about the sense of vision, something we use almost all the time and practically take for granted.
We recap the important points from this masterclass.
We will learn the essentials of inertial navigation, about sensors such as accelerometers, gyroscopes and magnetometers and how we can use the information they provide to estimate our motion and orientation in 3D space.
Many technologies have been developed to determine the 3D-structure of the world. RGBD sensors such as the Kinect use structured light, projecting a pattern of light onto the scene and observing how it is distorted. Time of flight sensors measure the time it takes for a pulse of light to travel from the camera to […]
Vision is a ubiquitous sense and is found in almost all animals, but the number and type of eye is very diverse. We will look at examples such as compound eyes of insects, spiders, and sea creatures such as scallops and squids.
A color camera has many similarities to the human eye. Instead of three types of cone cells a uniform silicon sensor uses a pattern of three color filters known as a Bayer filter.
Why do robots need a sense of vision in this modern age when GPS satellites can tell a robot where it is? Let’s talk about GPS, how it works and its strengths and weaknesses such as multipath and urban canyon effects.
Let’s recap what robots are, where they’ve come from and what they can do. Robots use sensors to understand their world and plan an action to achieve their goal.
A robot joint controller is a type of feedback control system which is an old and well understood technique. We will learn how to assemble the various mechatronic components such as motors, gearboxes, sensors, electronics and embedded computing in a feedback configuration to implement a robot joint controller.
