CURI – 4 by George Katz

VW_Touareg_MY2011_02-01The CURI-4 platform was developed to investigate a layered behavioral control scheme for a mobile robot. CURI-4 is a small tethered robot equipped with a camera and a gripper for grasping objects. The tether carries data as well as power. The main robot components are 2 DC motors with gearboxes for the drive mechanism, 4 RC type servo motors, a small CCD camera and custom electronics for the motor control. The drive configuration is a tripod with 2 individually powered wheels and a static caster skid. One servo controls the pitch of the camera, 2 servos are used in the gripper, and the fourth servo is used for a leg that allows the robot to tilt raising and lowering the gripper. The camera can be positioned so that it can image it’s own gripper in order to see what it is picking up. Continue reading

Trilobot Mobile Robot

The Trilobot mobile robot combines the latest in microcontroller and sensor technology with a strong, lightweight frame to create an affordable, rugged platform. Perfect for research in artificial intelligence, artificial life, autonomous navigation, robotics technology, and even maze competition. High-level commands can be sent to the Trilobot’s on-board controller from a PC using a serial (RS-232) interface. The user can place a laptop computer on the upper deck of the robot or communicate via wireless data links. The user can then control the Trilobot using any terminal program or by using popular programming languages such as C, BASIC or Pascal. Controllers can be daisy chained together for unlimited expansion capability. The simple two-letter command structure makes programming quick and efficient. Continue reading

Rear Wheel Trouble Continues

design1Results of diagnostic tests on Spirit’s right-rear wheel on Sol 2109 (Dec. 8, 2009) continue to indicate a troubled wheel, which may leave the rover with only four operable wheels. The Sol 2109 plan included a check of the grind motor of Spirit’s rock abrasion tool (RAT) because it shares the same motor controller as the right-rear wheel. It also included rotor resistance tests on the right-rear motor at three temperatures using opposite voltage polarity from earlier tests, backward and forward commanded motion of the right-rear wheel, and a check of rotor resistance on all other operating wheels. The RAT motor appears okay, although a more exhaustive test will be tried later. Continue reading

WISE Launch Delayed 24 Hours

design1Liftoff of a Delta II rocket and its NASA payload, the Wide-field Infrared Survey Explorer (WISE), has been delayed 24 hours. At the soonest, launch now will be Saturday, Dec. 12, during a launch window that extends from 6:09:33 to 6:23:51 a.m. PST (9:09:33 to 9:23:51 a.m. EST). The delay allows the launch team additional time to troubleshoot a technical issue. During final systems checks of the Delta II rocket Wednesday in preparation for flight, an anomaly in the motion of a booster steering engine was detected. Continue reading

Model Railroad on the Internet

If you want to put your robot on the Web I recommend you take a look at some interactive devices on the Internet. A good first stop is the University of Ulm’s model railroad. When you visit their Web site, you are entered into a queue of people who may issue a command to one of two Schnell Zugs and / or leave a message to the other operators. Second, issue your command (by clicking on a train and a destination) and sit back to wait. Continue reading

RoboSim

Wanna fun robot simulator? I recommend you download a robot simulator from Luiz Felipe Rudge Encarnacao. It includes an untethered mobile gripper with 5 degrees of movement in a 3-D room of objects and a toy airplane flying around in the same room. This is a Windows program that runs well on a Pentium and doesn’t lose its usefulness on a double speed 486. Continue reading

Stable Hopping Leg

Robert Ringrose of MIT demo’ed a very cool design at AAAI97. His Hopper robot leg stands on its own, and, when activated, hops straight up and down, maintaining its balance. It corrects its balance if you shove it to one side. It can be adjusted to hop forward, backward left, right, etc., simply by changing its center of gravity. The hopper will move in the direction of its mass. Continue reading

Mutant Machines

Mutant Machines is a Television series shown on the Granada Men and Motors satellite channel. It is Scrapheap Challenge meets Combat Cars. Two teams of three people were given the task of creating a powerful, useful, motoring related machine from two or more donor machines. One challenge was to make a four wheel drive, four wheel steering car from two front wheel drive cars. Continue reading

The Micromouse Contest

The micromouse competition is to build a small mobile robot that can solve a standardised maze. The competition has been running for over 25 years and is popular in the UK, USA, Singapore, Japan, Taiwan, Hong Kong, Australia and elsewhere. This “maze solving” contest was designed to challenge graduate electronic engineers. Continue reading
