Gabby has five goals to achieve this school year. The first goal sounds like any other young middle schooler: get straight As in her classes. Goal number two: get accepted into her school’s robotics team, followed closely by number three: to own her first VEX IQ Robotics kit. That’s when you may realize, Gabby is an extraordinary middle schooler!
Some people swear all tethers are bad. Some recommend attaching a tether to robots in order to provide power (to save the mass and volume of the batteries), for reliable fast communications, transfer of pressure or fluid, to track a robot’s position, or as a safety harness (in case the robot needs to be dragged out). However, before designing a tether there are several things you need to consider.
In this episode, Ron Vanderkley interviews Jürgen “Juxi” Leitner, a researcher at the ARC Centre of Excellence in Robots Vision in the Queensland University of Technology in Australia. Leitner speaks about a system being developed for the Google Lunar XPrize, called LunaRoo.
Time synchronization affects many robots. Robots have more computers and sensors, so keeping everything in sync is important. Trying to look through log files where all of the times are skewed is not fun and makes processing difficult. Merging sensor data together with GPS can also be disastrous if the times are offset. Further complicating time synchronization is that the robots are often not connected to the internet, so utilizing public time servers will not work.
