Google’s Laws of Robotics

Google plays hard to get a big piece of cake from the whole robotics industry with SCHAFT, Redwood Robotics, Meka Robotics, Holomni, Bot & Dolly and Boston Dynamics. With such impressive portfolio of robotics companies, Google has the influence and power to create trends and design technologies for the robotics world. Even better, they have created its laws of robotics.

So, for the moment forget the Isaac Asimov’s laws of robotics and take a moment to read the Google’s laws of robotics. Fastcodesign present them in a concise and easy to understand way.

  1. Robots should not make things worse;
  2. Robots shouldn’t cheat;
  3. Robots should look to humans as mentors;
  4. Robots should only play where it’s safe;
  5. Robots should know they’re stupid;

What Part of The Mindstorms Would You Change/Upgrade If LEGO Build a New Kit?

The LEGO Mindstorms kit ($350 on Amazon) is built to inspire and make you smile from ear to ear for a long time. But we grow up and need to use more and advanced technologies. For example, a development board like Raspberry Pi has been released with a built-in WiFi module. With this new version, it entered in the Internet of Things world as it is, a WiFi compatible single board computer. No accessories and other stuff.

So, if tomorrow LEGO will build a new Mindstorms kit, I want to:

  • be connected to the Internet in minutes without using a USB WiFi dongle that is supported by the firmware. I want to control my robot from the Internet;
  • easily connect my robot to an IoT platform for real-time status of the sensors;
  • prototype outdoor robots (big wheels, large DC motors, etc.);

If a LEGO engineer asks you today what part of the LEGO Mindstorms would you change/upgrade if the company build a new kit, what would be your answer? Please leave your thoughts in the comment section.

DFRrobot Announces Four New Turbo Metal Gear Worm Motors: 6V 40RPM, 6V 160RPM, 12V 40RPM and 12V 160RPM

DFRrobot announces four new turbo metal gear worm motors with 40RPM and 160RPM.

The first two metal gear worm motors have a rated voltage of 6V. The 40RPM version can produce a stall torque of 10 kg/cm while the 160RPM version produces a stall torque of 2.8kg/cm.

The other two metal gear worm motors have a rated voltage of 12V. The 40RPM version produces a stall torque of 8kg. cm while the 160RPM version produces a stall torque of 2.2kg.cm.

All the metal gear worm motors are priced at about $18.90.

A robot that could effectively replace casino croupiers in the future

This is a guest post.

She has a perfect figure, a calm demeanor, and a friendly face. Meet “Min,” the first-ever robot whose purpose is to mimic the job of a master casino croupier in Las Vegas and Macau.

The life-like, lady croupier is a prototype that was created by Hong Kong tech and gaming machine manufacturer Paradise Entertainment. Min, along with other casino croupier robots, were first introduced at a gaming show in Macau late last year. This 2016, they will be introduced in the U.S. where wages of employees in casinos are significantly higher than in South East Asia.

Currently, Min’s function is limited to dealing cards. However, planned enhancements could have Min recognizing customers’ facial features and speaking to them in several languages. This an effort to further humanize the croupier robots. Such responses wouldn’t necessarily have to come from the same robot, either as they will be interconnected via wireless transmissions.

If successful, even online, live casino dealers that offer a realistic casino experience in the comfort of a player’s home would be affected and it would certainly shake up the industry. If we are to follow the trends of Gala Bingo, a UK-based entertainment company that specializes in bingo and slot games, which has been in the news recently because it has begun shut down most of its land-based operations such as its popular bingo halls to focus on its online offerings, the need to introduce cutting-edge technology to casinos has never been more important. And the introduction of robot croupiers was going to happen sooner or later, so that these land-based casinos could wrestle back some of the market share they have lost to their digital counterparts, otherwise more casinos and bingo halls would be forced to close across the globe.

The Autonomous Hexapod Robot Designed To Navigate a Simple Maze

If you’re looking for ideas to build a robot this summer, Spider Pig is an engaging autonomous hexapod robot that uses three microcontrollers and a Raspberry Pi 3 Model B to navigate a simple maze.

The project is the result of a group of seven students that studies physics and electrical engineering at Linköping University, Sweden.

Main hardware:

  • 1x PhantomX AX Metal Hexapod Mark II Kit (including 18x Dynamixel AX-12 servos, excluding the ArbotiX Robocontroller)
  • 3x ATmega1284p microcontrollers
  • 7x IR distance sensors
  • 1x ultrasonic distance sensor
  • 1x MPU-6050 IMU
  • 1x LCD display
  • 1x FireFly Bluetooth modem
  • 1x Raspberry Pi 3 Model B
  • 1x Raspberry Pi Camera Board 5 MP

The robot can navigate autonomously or controlled manually with an Xbox controller connected to a PC. The controller communicates with the PC over Bluetooth.

The robot has attached three microcontrollers. It seems a multitude of microcontrollers, but each of them controls a subsystem of the robot. One microcontroller is for communication, one for sensors and another one for control. Read more →

The Hobbyist’s Guide to 6V 6A/5A/4A Acid Batteries for Every Budget

A good battery will keep running your robot for a long time, but it’s hard to find the best battery for a specific project.

DINO: The Robot Designed to Mow the Weeds From Large Vegetable Farms 10 ha (24 acres) Or More

Naïo Technologies just announced the second version of Oz, an autonomous robotic weeder for large-scale agriculture called Dino. Let’s take a look.

Dino is a 4WD robot platform designed to save time for farmers and increase the productivity of the farm. A well-equipped robot like Dino can maintain soil structure, limit chemical input, respect crops, and work 24/7 to increase farm productivity.

First was Oz, a small autonomous robot, a prototype able to mow the weeds between vegetable rows. Now is Dino, a large autonomous tractor that can be equipped with laboring tools to adapt to soil and crop type.

A massive tractor compact soils affecting the water penetration. Dino claims to be lighter and more energy-efficient than a tractor, so it avoids compact soils and reducing plant growth.

Technical characteristics

  • Speed 4 km/h
  • Size Length 2.20 m / Width 2.10 m / Height 1.30 m (beds from 1.20 to 1.80 m)
  • Weight (w/o tools) 600 kg (depending on battery and tool configuration)
  • Autonomy 8 hours

€150.00 TeraRanger One Distance Sensor For Robotics With Range Between 20cm and 14m

A high precision navigation sensor for autonomous navigation rarely is found among makers and hackers. There are at least two reasons: the price and compatibility with the development boards.

TeraRanger One is new in the range of high-precision sensors for robotics. The sensor is based on infrared Time-of-Flight (ToF) technology and claims to be faster than ultrasound and far smaller and lighter than laser-based systems.
