The film ‘First Man’ celebrates the life of Neil Armstrong, the first man to set foot on the Moon. But what about that unsung hero, the vehicle that took him there: that engineering marvel, the Saturn V rocket?

The UK government has a manifesto commitment for all cars and vans on the roads to have zero emissions by 2050. So, unless ‘wireless power’ can be developed quickly, cars will need electric motors with batteries or fuel cells for energy storage.

Wheeled robots take many forms: 2-, 3-, 4-, 6- or 8-wheels, with and without suspension. The type of terrain the robot will move over largely determines the choice: a nice, smooth warehouse floor or a rough, unpredictable Martian surface?

In November 2015 I suggested in a DesignSpark article that ‘Your Car will soon be Driving You to Work’. After nearly three years of frantic activity by engineers and marketing people, are autonomous cars any nearer becoming a reality?

Part 1 covered the theory behind PID control. Part 2 discussed the practical issues of odometry and using PID for precise mobile robot navigation. Now let’s look at some more code and other features of practical rover design.
An AI-equipped ‘astronaut companion’ called CIMON is on its way to the International Space Station. With fictional androids starring in TV shows Westworld and Humans, just how close are we to creating a socially-acceptable companion robot?
Part 1 covered the theory behind PID control – a widely used method of ensuring that the mechanical output of an actuator (speed, position, etc) matches the value demanded by its controlling program. Now let’s look at practical aspects in detail.

Mobile robots can be divided into two classes: those that navigate around solely by sensing and avoiding obstacles, and those that move along a planned path using an internal electronic map. For the latter, you need mobility control.

What soft robots lack in hard strength and precision, they make up for with their gentle dexterity handling delicate objects, or their ability to go places other robots cannot reach.

Industrial robots are big, expensive, inflexible and dangerous to human workers, right? Wrong, the next generation of Collaborative robots or Cobots can operate alongside humans and don’t need to be caged or fenced off.

A computer security company has just described very serious security weaknesses in AMD microprocessor devices. This follows similar problems discovered with Intel and ARM-based chips. In this age of automation, just how dangerous are the threats?
