jwatte replied to a thread Temi in Rovers

What do you mean by "personnel teleportation device" ? With two 50W motors, I don't think a human being is supposed to ride on it? Maybe this is a...

jwatte replied to a thread Question(s) DYNAMIXEL MX-28 Velocity Mode is Not Working Properly in DYNAMIXEL & Robot Actuators

How long does it keep moving slowly? Forever? Which value do you write to the goal velocity register to write a "zero" target? If you bump it up...

jwatte replied to a thread Question about a particular omnidirectional robot design in Robotics General Discussion

I've heard it called "omnidirectional steering" but I don't know if there's a more accepted name in practice. Given that these aren't particularly...

jwatte replied to a thread Question(s) Can't connect to Dynamixel MX-106T servo on dynamanager in Arbotix, Microcontrollers, Arduino

Do you have a USB2Dynamixel or perhaps a U2D2? Then you might be able to use the Dynamixel Wizard to see if you can scan to find the servo. You can...

jwatte replied to a thread <DynamixelWorkbench.h> with <ros.h> problem on Arduino IDE in DYNAMIXEL & Robot Actuators

I think the problem is in ROS code, not Dynamixel code. USBSerial is not (necessarily) a HardwareSerial. They might, for example, want to use Stream...

jwatte replied to a thread <DynamixelWorkbench.h> with <ros.h> problem on Arduino IDE in DYNAMIXEL & Robot Actuators

It looks like the ROS library is hard-coded to expect a "real" serial port, which is reasonable on old-school Arduinos, but not later ones like the...

Twitch - 3 Servo hexapod
- Created by Gertlex
- Synopsis: Twitch is a 3 servo hexapod (for lack of better classification). Twitch is controlled via two Wixel boards and an Arbotix Commander. The mobility of Twitch far greater than any other approach to a 3-servo walker that I have seen, and makes for a cheap bot that I can let anyone try driving.
