Worm gearbox for steering
I'm planning on making a smallish off-road rover (15-25kg net weight) with 4-wheel steering and I was wondering if it'd be a good idea to use (self-locking) worm gearboxes for steering. I've thought ...

Steering using different speeds in DC motors or using a servo?
I am trying to assess the pros and cons of steering a robot car using different speeds of 2 or more DC motors versus using a servo and a steering mechanism? From your experience which is better in ...

How to determine the required CPU speed for a micro-controller with a 2-phase encoder attached to interrupts?
I am building a high-torque steering servo. I am trying to use the Adafruit Feather M0, which has a CPU speed of 48MHz, to monitor a 2-phase encoder that has 2400 pulses per rotation. I have attached ...

Overcoming or managing dead time in vehicle steering controller
I found out there is a dead time in my steering controller after several runs. The transfer function for it in the $s$-domain is:
$$
H(s)=\frac{270 \cdot e^{-0.03s}}{0.015 \cdot s + 1}
$$
To ...

Motorised steering without shock absorber?
I was looking up on the Curiosity Mars Rover and noticed that the steering appears to be driven by a (geared) stepper:
I presume the drive contains a worm gear to reduce power consumption of the ...

Differential steering
I'm hoping to build a 40kg rover for running on soft and loose dirt by using fewer than 4 motors. Does anyone know if differential steering is possible on 3 actuated wheels? That is, two at the front ...

Tuning PID controlling car's steering angle
We built a car model with Ackerman steering type for line following task. The distance between rear and front wheels' axes was about 42 cm. Then we tuned PID controller (really just PD: Kp = 0.9, Ki = ...

Do the distance function and steering function in an RRT have to be related?
I am developing an RRT (rapidly exploring random tree) for car-like robots in SE2 space using Dubins steering function and have a question that has implications on the performance of RRTs.
In order ...

How can I feel feedback with electric power steering (EPS)?
When I am rotating steering wheel and it meets an obstacle, I feel it. I have EPS. How does it work? Is it just explicit sensor and feedback? Can I sniff this feedback on CAN bus?
