Balancing Hexapod

Forum User jpieper has made a 3DOF quadruped robot of his own design, using Dongbu DRS-0101 servos. It starts off slowly, but is surprisingly speedy and exceedingly steady. This robot has since been upgraded with a turret and a gimbal, making it Mech Warfare Ready. Check out the thread for more updates! jpieper has a new chassis in the works, and intends to use an integrated odroid daughterboard in the next version. Very cool!

cheeky nandos

Turn up your speakers! Customer teethoflions posted this entertaining video of his HR-OS1 being cheeky. What song will your robot dance to?

Want to control your Trossen Robotics PhantomX Hexapod with an iPod/iPad? User reneca has done just that. There seems to be a bit of lag on their camera, but the controls look spot-on. The project files are available on GitHub if you’re looking to try it out for yourself!

Oregon State University’s Bipedal Robot: ATRIAS

Monday, May 11th, 2015

Rhoeby

ATRIAS, built by the Oregon State University’s Dynamic Robotics Laboratory, directed by Dr. Jonathan Hurst, is an awesome bipedal robot. ATRIAS is capable of balancing itself on changing terrain, rolling hills, and even while being pelted by dodgeballs! This robot is clever, and we wish the team lots of luck at the DARPA Robotics Challenge in Pomona, CA on June 5-6, 2015.

ROS enabled PhantomX Hexapod

phantomx hex w kevino ros

User r3n33 has deployed KevinO’s ROS development onto a PhantomX Hexapod with a Raspberry Pi 2! This is an involved process, and it is awesome to see an already solid ROS package get some well deserved attention. It’s awesome seeing what happens when the robotics community comes together to focus on something spectacular.

RTEAM’s new Mech Warfare Robots!

Friday, May 1st, 2015

rteam

RTEAM Robotics Club from Tuscon, Arizona has been expanding their army of Mech Warfare combatants! Currently, they are testing out the use of Piezoelectric Speaker Scoring Panels instead of the FSR panels that have become a standard lately. This came about due to the expansion in number of mechs, and a lack of materials for half of them. User giantflaw offered some insight as to the continued use of Piezoelectric Speaker Scoring Panels:

RTEAM piezoelectric target plates are fully compatible with the existing target plate system and I think offer 6 advantages over the FSR plates. 1.) They are much more sensitive than the FSRs 2.) They register target plate hits reliably every time and never resgister any robot vibration or shock to the robot. The target plates are oblivious to walking gait. 3.) They are much cheaper than FSR target plates and easliy made with analog components. 4.) They can be de-tuned to be less sensitive and mimic an FSR low sensitivity target plate. 5.) There are no dead zones in the target panel like there are on FSR target panels. 6.) The target panel can be any shape or size unlike the FSR target panels. 7.) The target panels are tougher than the FSR plates and are not easily damaged.

If you’d like to see what the buzz is all about, hop in on this thread!

Project Rhoeby is navigation capable.

Rhoeby

Forum user and roboticist madhatter101 has just introduced his newly ROS enabled hexapod, Rhoeby! Built on a Robotis Bioloid kit, it uses a TeraRanger 2D LiDAR (from Rhoeby Dynamics, hence the name) to scan its surroundings. It supports SLAM, Navigation, and Dynamic Obstacle Avoidance. Rhoeby is pretty slick, more details on the forums.

KevinO’s ROS Hexapod Golem

Wednesday, April 22nd, 2015

robot publisher test

Roboticist KevinO has been up to some really amazing stuff with his ROS Hexapod “Golem”. We’ve highlighted this robot before, but it just keeps getting better. The leap he’s made using mathematical odometry via Rviz in ROS is worth noting. Point cloud data (registered as a fake laser scan at robot height), IMU, and visual odometry from the Depth Sensor data are compiled and used by the mapping and navigation stack, then subsequently passed to a Kalman filter (a linear quadratic equation used to observe measurements over time). That’s a pretty comprehensive stack, giving the robot a good sense of its place in the world (as in its position in space, not in the annals of history).

 

Here’s what the point cloud scan looks like in rviz.

And here’s what an odometry plot looks like.

This project has been pretty impressive every step of the way. Golem has many abilities, including a smooth walking gait, body leveling via the IMU, text-to-speech ability, and now a much improved mode of navigation. This project was originally noted to be a ROS learning project, and I can’t wait to see what Kevin learns next!

HR-OS1 Humanoid Endoskeleton Shipping Has Begun!

Monday, April 20th, 2015

HROS-1 Staging

We’re happy to let you know that we’ve shipped out the first 15 HR-OS1 kits! If you’re one of the people who we’ve shipped to you should receive an e-mail with your tracking number shortly. We are on track to have the next 20 kits shipped out by the end of the week. The last 15 kits will be shipped out early / mid next week.

Hexapod Navigation Through Environment

hexapod navigation through environment

Check out roboticist Christopher’s Hexapod navigation through environment with 33% hole coverage (slow)! Though the gait is slow, this looks like a very intelligent terrain mapping addition to the PhantomX AX Hexapod. We suggest watching this at 2x speed, but it’s worthwhile to see what can be done with a bit of ingenuity!
