UGV

Dagu Robot Chassis Steering

Problems with the steering. It's too tight. The motor won't even turn. My model has 3 flat spurrs set up in the steering. 1 for the feedback pot and one for the turning axis, and 1 for the motor. When they are linked together it gets too tight and the motor tries to spin, but it can't.

Do I need to return it and get another one..

Do I need to have replacement parts sent to me....

Should I send it back and get a different car to map with my Micro Magician Motor controller....

Is there anyway to troubleshoot this issue and make it work without sending it back?

AGV

Here is my AGV. It drives to GPS waypoints.  It is currently using a Arduino, GPS, and of course a motor controller. The bot itself is a Hummer RC truck from … Read more

Iphone controlled XMOS powered UGV robot!

Another XMOS robot I have found, made by people at University of Denver.

Demonstration of XMOS real-time ability. This test is running 8 independent tasks: gps task, ultra-sonic task, compass task, wifi receive task, wifi transmit task, pwm output task, behavior task, status led task:

UGV Monster truck platform

I'm planning to build a UGV monster truck, based on a Tamiya Super Clodbuster. I've heard that it's a lot cheaper if you buy it in pieces. However, I ran into a bit of a dilemma. The stock monster truck comes with a speed controller. Do I need that too (I don't need any RC functions) or can a motor controller for Arduino or Basic Stamp do the job too. I already own a BS2 with BoE, but I would like to buy an Arduino because it's cheaper, open-source etc. Note: I'm still a beginner in robotics.
