The second generation of robotics is now upon us, as end of line and bench robotics are becoming economically accessible, robotic integration within industry is no longer only associated with large scale production and automotive assembly lines. Pick and place single arm, multi-axis robots are more popular than ever as users see both their cost and operational benefits. Capable of working along-side humans they perform the repetitive precision work required, faster and without fault.
This hub is the place to find out more about robotics, whether its kits or design ideas you need, or simply to just discuss more about this technology. Check back for latest updates.

@Bill Marshall This is my proposed solution here: https://hackaday.io/project/53896/log/152467-getting-the-machine-to-drive-downhill …. Not sure how to size the resistor Ohms - I've asked Ampflow, the...
@TegwynTwmffat You're right about the generator action, but that's how a PMDC motor works. A Back-EMF (Electromotive Force) develops across the motor as it speeds up. This opposes the input voltage, causing...
@Bill Marshall Thanks for reply - it helps! I'm going t add an optical encoder to the machine and apply PID. I've further researched the problem and seems like it might be because the motor starts to act...
@TegwynTwmffat I'm guessing that the motors speed up as you start to go downhill. From what you say, I think this is what's happening: Those VEX driver modules contain a PID control loop designed to maintain...
I'm still struggling with going downhill - I've even swapped out the drive motors to pair of Ampflow A28-400-F48 with Vex victor BB controllers. I'm thinking it's either the 100:1 wormdrive gearbox or...
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?
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.
Creating a multifunctional robot may seem difficult, but after reading this article you should be able to build one of your own.
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.
I know the children are our future and all that, but sometimes I think they get all the fun. So I am really excited to be going to the UK MakerFaire in Newcastle 28-29 April 2018.
Have you seen Norbert Heinz's WinchBot 2.0? The WinchBot 2.0 is a robot that anyone can replicate, with the plans, assembly instructions, parts lists and RS parts lists openly available.
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.
