Skynet will have Bobcats

There are so many autonomous devices nowadays that can run Skynet Inside™ that it’s hard to keep track. But one was still missing: the versatile Bobcat. When we say “Bobcat”, we mean track loader — it’s just one of those things that the name and the brand stoke together so strongly that it’s hard to actually recall the technical name. A company by the name of Built Robotics is betting on autonomous track loaders as being a big part of the future of construction.

The tractor can navigate, excavate, and carry a 1,000 pound load with 1 cm precision …read more

Soon You’ll Sit Inside a Robot’s Head at Work

MIT’s Computer Science and Artificial Intelligence Lab, CSAIL, has created a process of teleoperating a Baxter humanoid robot with an Oculus Rift VR headset. This project is partially aimed towards making manufacturing jobs a hell of a lot of fun telecommutable. It could even be a way to supervise robot workers from a distance.

In a nutshell, the user controls the robot remotely in a virtual reality environment. The user does this specifically in a VR environment modeled like a control room with multiple sensor displays, making it feel like they are sitting inside the robot’s head. By using hand …read more

Simple Step-Climbing Robot Climbs Like It’s On Mars

[Navin Khambhala] is a master at making simple what most would expect to be a complex build. Now he’s done it again with a remote controlled robot that can easily climb steps and role over rough terrain. The parts count is small and many of them are commonly available.

The suspension that makes it all possible is the rocker-bogie. It’s the same suspension we’ve all seen used by the various rovers ambling around on Mars. The whole frame is made of PVC pipes with some connecting metal bars, and each wheel has its own twelve-volt DC motor. Motor control is …read more

Wooden Domino Laying Machine

[Matthias Wandel]  has come up with another awesome machine, this time a machine that sets up neat rows of dominos. If you’ve followed [Matthias]’s work over the years then you’ll know that this is a wooden version of one he made out of LEGO® back in 2009.

In true [Matthias] fashion he uses just the one motor both for moving the machine along and for pushing the dominos in place. Not satisfied with that efficient use of parts, the rubber band belts that transfer rotation from the motor shaft to the wheels (bearings) double as the rubber surfaces for those …read more

Robot: Do My Bidding!

Remote control robots are nothing new. Using Bluetooth isn’t all that unusual, either. What [SayantanM4] did was make a Bluetooth robot that accepts voice commands via his phone. The robot itself isn’t very remarkable. An Arduino and an HC05 module make up most of the electronics. A standard motor driver runs the two wheels.

The Arduino doesn’t usually do much voice processing, and the trick is–of course–in the phone application. BT Voice Control for Arduino is a free download that simply sends strings to a host computer via Bluetooth. If you say “Hello” into your phone, the robot receives *Hello# …read more

3D-Printed Rover Rolls Light and Looks Right

[Rick Winscott]’s RO-V Remotely Operated Vehicle instructable shows you how to make this cool-looking and capable robot. The rover, a 1/10th scale truggy, sports a chassis printed in silver and black PLA. It’s got a wireless router mounted on the back, and a webcam in a 2-servo gimbal up front. [Rick] made his own steering rack and pinion out of 3D printed parts and brass M3-threaded rods which he tapped himself.

The simplified drive system nixes the front, rear, and center differentials, thereby saving [Rick] on printing time, complexity, and weight — he was able to include a second 4000 …read more

ESP32 Mini Robot Packs Sensors and 4WD

[Stefan]’s Mini WiFi/BLE 4WD robot platform (seen next to a matchbox above) packs an impressive capability into a tiny rover. It’s based on a SparkFun ESP32 Thing, a very compact way to add wireless control to your project. Compare it to some giant old UNO with a WiFi shield, these boards are small but powerful, as well as an easy adoption for Arduino fans.

[Stefan] beefed up the robot with a BNO055 module to determine orientation, an APDS-9930 proximity sensor, as well as four CNY70 IR proximity sensors on the bottom, used for line-following. A pair of 6 V motors …read more
