Tech Thursday #012: PulsedLight LiDAR-Lite

PulsedLight’s LiDAR-Lite (TS-070-001) is a compact and high performance distance measurement sensor. The small size and light weight makes it an ideal positioning sensor in mobile robotic applications. The sensor also boasts an incredibly wide operating range. It can accurately measure from about 5cm all the way up to 40 meters! This makes the sensor great for both precision and distance mea...

Tech Thursday #011: Motion Detector Servo Control

Home automation is a hot topic these days. In this week’s Tech Thursday I will show you how to deploy a simple motion sensor and use it to set the position of a servo. For motion detection I will be using our Mini PIR motion detector module (TE-232-805) as our detector, and an Arduino Uno and a Pololu Maestro6 for our controls. The Pololu Maestro provides a simple and easy way to control mul...

Tech Thursday #010: Pneumatics

Pneumatics opens up a world of possibilities when it comes to robotics. You could write a book on applications of pneumatics but for now we will start with the basics. Knowing what you need is sometimes harder than knowing how it works. For this example we are going to control an air cylinder extend and return slowly. We will be using a switch to turn on a solenoid valve and exhaust valves to cont...

Tech Thursday #009: PID Control

PID control (Proportional-Integral-Derivative) is a major building block of a robotic system. It provides a straight-forward method to precisely control a motor to perform a pre-determined action without the need for direct human control to adjust the machine. PID control is an algorithm that uses a determined error that can be used calculate the necessary motor response to achieve your task. Open...

Tech Thursday #008: Robotic Arms

We recently listed three arms for sale on the website as stand-alone items. Two of them are heavy-duty arms that we use with our tactical robots. One of these is our HD2 Multi-Axis Arm (TP-702-000), a large 5-axis arm that we use with our HD2-S Mastiff. The other is our LT2 Multi-Axis Arm (TP-701-000), a smaller 4-axis arm that we use on our LT2-F Bulldog. The third arm we listed is the Dagu 6DOF ...

Tech Thursday #007: Spektrum Binding Procedure

With many of our projects, we set them up with simple RC control for initial testing. This lets us verify the robot’s mechanical features and power distribution are functioning properly before implementing more advanced control methods and/or autonomy. We tend use Spektrum brand remotes and receivers for their ease of use and reliability. Depending on the receiver they can bind two different...

Tech Thursday #006: RF Joystick Motor Control

So we wanted to make a simple remote control for a robot. We could have used a Spektrum remote, but they are kinda bid and clumsy and only one way comms. So in this tutorial we show how to hook up the nRF24L01 2.4GHz Wireless Transceiver Modules. The remote will have a simple analog 2-axis joystick. The robot will be attached to a Sabertooth 2×32. When the joystick is moved, the motors will t...

Tech Thurday #005: Arduino to Arduino Serial Communication

Serial communication is a major backbone in embedded electronics and it is exceptionally common to have two embedded devices to talk to one another. For example, you may have one Arduino reading joysticks and sensors and another wired into a robot to command motors, servos, relays, etc. Today’s Tech Thursday will walk you through basic Arduino to Arduino serial communication. Schematic Below...

Tech Thursday #004: 3D Print Molding

Do you have a 3D printer? Try this to make higher quality parts with different materials that probably can’t print with your 3D printer. 3D printers are great for prototyping but when it comes to make a part that needs to be durable they usually struggle. You can, however, use them to print a mold of a part and then use a two-part urethane, epoxy, or any other curable liquid material to cast...
