Driving Mecanum Wheels Omnidirectional Robots

Driving Mecanum Wheels Omnidirectional Robots

See how to build an omnidirectional robot with just two Roboteq dual channel DC motor controllers to independently drive four mecanum wheels. The two controllers operate as a single four channel drive over a CAN network.

Driving Sensorless Brushless Motors


sensorless BLDC thrusters with roboteq motor controller
One can now find an abundance of sensorless BLDC motors, mainly from China. These motor are primarily addressing the Drone and Hobby market but, thanks to their excellent characteristics and low cost, they find their ways in an increasing number of robotics and industrial applications. Roboteq FBL2360 controller with 2 T200 sensorless BLDC thrusters from Bluerobotics Roboteq controllers now suppor...

Field Oriented Control (FOC) Made Ultra Simple

foc idiq
Every modern motor controller for Brushless motors now features Field Oriented Control (aka VectorDrive). But what is it exactly and how does it work? One way to figure this out is to look on Wikipedia, or most other articles on the subject on the internet. There, the explanation are complete and accurate but often filled with too much math formula to actually make practical sense of it. Yet, Fiel...

How Resolvers Work

resolver photos
Resolvers are absolute angle sensors that use entirely passive transformer technology. Resolver offer reliability benefits over other technologies and are perfectly suited in extreme temperature, oily, dusty or even radio active environment. Resovers are now supported in all new and updated version of Roboteq's brushless motor controllers. Resolvers is an analog position sensor that is absolute ov...

How SSI Encoders Work

ssi
When operating brushless DC motors, knowing in real-time, and with precision, the position of the rotor is a prequisite to best performance in sinusoidal commutation. While numerous sensor techniques exist and are supported by Roboteq, Synchronous Serial Interface (SSI) is by far the best at is provides an absolute position with great resolution at very fast update rates. Synchronous Serial Interf...
