Motors

Most mobile robots have actuators that rotate continuously – often these drive wheels. As a motor rotates, so the wheel rotates and the robot moves. Many robots have two wheels, …

ERIC’s light sensors

In this video Richard shows how light sensors work in robots such as ERIC. This demo is followed by a brief clip that shows some ERICs using their light sensors; …

Ultrasonics

In this short video, Richard explains how echo location is used by a robot to measure the distance and location of another object. You will have the chance to get …

Accelerometers

Not only do robots want to measure velocity, they sometimes also need to determine change in velocity – that is acceleration. Accelerometers can be used for measuring acceleration and in …

Sensing and Computing

As humans, we primarily sense our world visually, using our eyes. Our two eyes help for instance to work out how far away an object is and so it seems …

Sensors and Actuators

Sensors are devices which measure quantities which the robot can use to achieve given tasks. Examples of what a robot may need to determine include: How far away and where …

Internal sensors

Internal sensors are used to measure aspects about the robot itself, such as how fast it is going and at what angle it is facing. When we consider how fast …

Bio and non bio-inspired sensors

Bio inspired sensors The ultrasonic sensor system is similar to that used by bats. Dolphins also use ultrasound for sensing and communication. Other biologically inspired sensors are possible. Whiskers – …

Passive and active sensors

A passive sensor is one which just ‘listens’ to what is happening. Examples include: A light sensor which detects if a light is shining on it An infra-red sensor which …

Robot and environment

Whatever type of robot we have: a robot arm, a wheeled robot, a ‘humanoid’ i.e. 2 legged robot, or a multi-legged robot (insect), it: will have a task to do; …

Set movement

In this second simulation, you will find out how to specify the speed in order to determine the movement of the robot. Before you get started, take a look at …

Robot battles

In this step, University of Reading graduate, Rory Mangles, writes about another robot application – Robot battles! You can read all about the events below and also follow the links …
