Why do we need control?

Last week, we saw that by using Pulse Width Modulation (PWM) we can generate the correct average voltage so that the motor rotates at the correct speed. We also noted …

ERIC negotiates an arena

Watch ERIC (and his friends ERIC and ERIC) navigate around an increasingly complex arena, demonstrating sensors in action.

Anatomy of a Rover

Richard reveals the internal anatomy of Rover – one of the University’s mobile robots What are the key differences between ERIC and Rover? Share your thoughts in the comment section …

Earthquake! Demo simulation with Rover

Watch Rover in action, gathering data during a simulated earthquake using x, y and z sensors, as well as measuring spin. Gathering data in a simulated earthquake is just one …

Define robot movement as it sees light

As we discussed in Step 2.9, some robots can have light sensors to sense if an object is nearby. This video, shows you how to define the speed depending on …

Anatomy of ERIC

Let’s now take a closer look at the different parts which make up our ERIC robot. In this video Richard reveals ERIC’s anatomy and why each component is so important. …

Actuators for robotic arms

There is a lot of work associated with robotic or prosthetic arms, devices which need to bend and move – for which actuators are needed. Most industrial robots are based …

Power supplies

The robots need power to provide the voltage signals that make the motors turn, the sensors operate and the robot brain. The simplest way of doing so is to use …

How to set and measure motor speed

To be able to set the desired speed of a robot, we need to first measure the speed of it. In the video above, Richard explains how we set and …

Robot program

Suppose a robot has a computer. Then that computer will have a series of instructions which it will obey. Ultimately those instructions are a series of electronic signals which computers …

Robot brains

So a robot has sensors and actuators. But what decides whether the robot should find out how far away an object is? Or whether the robot should set its motor …
