Tech Thursday #023: Wireless Robot Control with an xBee

When you want to take your robot wireless but want to take it a step past R/C, an xBee is a prime candidate. The system works over 2.4GHz, similar to WiFi but what it provides is a simple wireless serial bridge. Meaning you can send a packet to the module and it’ll appear at the outputs of all xBees on that network. You don’t have to worry about subnets and IP addresses or any other ne...

Tech Thursday #019: A Fun Tracked Robot with a Arduino

We had fun building this robot. He may look familiar… We started with MLT-JR custom length tracks and added a simple shell and head. The motors are driven with a Sabertooth 2×5 Motor Controller. All the parts (other than the drive train) were made with our 3D printers. Then we gave it a quick paint job. We embedded two IR sensors on the front and put a Arduino in the middle cavity to dr...

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...
