Lack of interest is a good question. Back in 2005 A workshop was organised by Geoff Pegmanon of R U RobotsLimited, held on 1st December 05 at SalfordMessage 45 of 45 , Jan 4, 2011View SourceLack of interest is a good question.Back in 2005 A workshop was organised by Geoff Pegmanon of R U RobotsLimited, held on 1st December 05 at Salford University, it was centred on future robotics research and development opportunities and aimed at both industrial and academic participation.Following it I sent a proposal for a biped robot competition.Geoff Pegmanon said he circulated it but never received any interest.At its simplest a radio controlled Bigfoot/Toddler with a gripper could have been entered!I think it was too hard for those attending the workshop.David----- Original Message -----From: Pete MilesSent: Saturday, January 01, 2011 7:23 PMSubject: Re: [SeattleRobotics] robot legs and wheels on challenging terrain
The original intent for the Walking Robot Race for the Robothon was for Humanoid
robots. We opened it up to all walkers so that they would have a contest to
compete in. Unfortunately, my robots were the only bipeds to enter the race.
If you can't get people to bring in a humanoid robot for a simple straight line
race, how do you get them motivated to enter one for something more complext.
I don't know why people don't get them to do more. I know there are a lot of
SRS members that have them. We just don't see them. I tried to get some
interest in a more agressive contest by entering in one into the 3 kg sumo
event. Yes it lost to the other wheeled robots, but I was trying to demonstrate
that it could survive the event without any real damage, and it did. But still,
no further interest.
For the most part, the walking robots that we build, humanoid/quad/hex, are not
going to progress beyond flat smooth surfaces until we are willing to risk
breaking the robot many times going after the rough terrain. Until then, they
make great dust collectors on the shelves. Which is a shame. We build them,
then get worried about breaking them, and move them to the shelves until we get
bored of them. The fate of all robots.

I think they are blended operation. RC but with software and sensors to augment
the control. As I understand it they have automatic routines for things like
standing up, using the 3-axis accelerometer sensor to determine what way they
are laying down.
I think it would be cool to have events like the humanoid obstacle course at
