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...

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 ...

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...

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...

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...

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...

We’ve uploaded new example code for the Roboteq SDC2130 to our Github account. This example code demonstrates simple motor commands and ramping and was tested on our Programmable MLT-JR Development Robot (TP-220-002). If you have any questions or comments regarding the provided code example, let us know on the forums. Links: SDC2130 Example Code User Manual SDC2130 Datasheet

SuperDroid Robots’ remote control SnowPlow and SnowBlower allow you to remotely remove snow while you stay warm in your home. We are looking for your backing to improve our designs, reduce manufacturing costs, and provide an option as a DIY package so we can offer the robots at a more affordable price. The remotely operated snow blower and snow plow are intended for the home, business, or mu...

We are a little early with this posting, but wanted to get it out before the holiday. So for our third installment of Technical Thursday, we figured we would honor Thanksgiving by provide a cool project idea of making a remote control turkey. If you hunter, this makes a great remote control decoy. Click on the image below to watch a quick movie. So the idea is relatively simple. Take a MLT-JR RC c...
