How do you calculate robot travel time?

Divide the total TCP travel distance per cycle by the sustained TCP speed to get base time, then multiply by (1 + allowance). With 2400 mm at 800 mm/sec, base time is 3 sec; a 20% allowance yields 3.6 sec of required travel time.

Why is real travel time longer than distance divided by speed?

The arm spends part of every move accelerating and decelerating, blending corners at reduced speed, and reorienting the wrist. The allowance percentage folds all of that in — here 20% adds 0.6 sec on top of the ideal 3 sec.

What is a good accel and blend allowance to use?

For long, smooth transfer moves 10-15% is realistic; for busy paths with many short segments and tight corners, 25-40% is common. When in doubt, 20% is a defensible planning default until you can measure a real teach program.

How is TCP speed different from joint speed?

TCP speed is the linear velocity of the tool tip along the path, which is what determines cycle time. Joint speeds vary constantly to produce it, and near singularities the TCP can slow dramatically even at full joint effort — another reason to keep an allowance.

Does travel time include gripping and dwell?

No. This figure is pure motion. Add gripper actuation, vacuum settle, and I/O dwell separately, then sum all segments to get the full cycle time against your takt.

How do I cut robot travel time?

Shorten the path with better home and via points, raise sustained speed where reach and payload allow, increase corner blending (zone/CNT) to avoid full stops, and minimize wrist reorientation. Each directly attacks distance or the allowance factor.

Robotics & Automation calculator

Robot Travel Time Calculator

Robot travel time is the number of seconds a robot's tool center point (TCP) spends moving through its programmed path in one cycle, adjusted for the reality that the arm never runs at full commanded speed for the whole move. Automation engineers and cell integrators use it to size cycle-time budgets before a single line of RAPID or KRL is written. It matters because motion time is usually the largest, most controllable slice of a pick-place or dispense cycle, and overestimating peak speed is the classic way quoted throughput evaporates on the floor. Getting this number right tells you whether one robot hits takt or whether you need a second arm.

What this calculator does

Estimate seconds of robot travel time per cycle from total TCP distance, the speed the cell can hold, and an accel and orientation allowance.
Use it when tuning a path or comparing two cell layouts so you can see the travel time impact before reprogramming or re-quoting takt.
It computes the seconds of TCP motion needed per cycle by dividing total path length by sustained speed, then inflating for acceleration, blending, and reorientation.

Formula used

Base robot travel time = total TCP travel distance per cycle / sustained TCP speed
Required robot travel time = base robot travel time x allowance factor

Inputs explained

Total TCP travel distance per cycle:
Sustained TCP speed:
Accel, blend, and reorient allowance:

How to use the result

Use it during cell concept and cycle-time budgeting, or when a running cell misses takt and you need to isolate motion time from gripping and dwell.
A single lumped allowance can't capture a path with many short segments where the arm never reaches sustained speed, so long jerky programs need per-segment simulation instead.

Current U.S. benchmarks

Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
